2. Frame regulations governing Priority on the Course.
3. Frame regulations governing practice during stroke competitions. (Rules 8-3, 36-4b.)
The complete specifications follow:-
This specification is divided into three sections: Section 1 refers to golf clubs where grooves are used; Section 2 refers to golf clubs scored with punch marks; Section 3 includes a combination of groove and punch markings.
Section 1
1. A series of straight grooves in the form of Vs may be put in the face of the club. The side walls of the grooves shall be essentially flat and the included angle shall be equal to or greater than 90 degrees. The bisector of the angle shall be normal to the face of the club (see Figure 2).
2. The width of a groove shall not exceed .035 inches along its full length. This width shall be measured in the plane of the face of the club and shall be between the two points where the planes of the groove meet the face of the club.
3. At no place on the face of the club shall the distances between grooves be less than three times the width of a groove, i.e. 25% of the area reserved for scoring may be grooved.
In the event that grooves are used with a width less than .025 inch, the minimum distance between the edges of the grooves shall be .075 inch.
The scored area shall be considered as that portion between the outer vertical lines shown in Figure 2. If only two vertical lines are used and these lines intersect the grooves, it shall be permissible to add to the length of the groove the distance between three grooves (2W) in determining the scored area. In no case can the total length be greater than 2W plus the length of the groove. The total length multiplied by the average width shall be the scored area.
The area of metal removed from the vertical lines or grooves shall not be counted in determining the percentage of area scored.
4. The centre of the scored area may be indicated by any design provided it does not exceed the boundary set up by a square whose sides are 3/8 of an inch. (See Figure 1). If manufacturers have no particular design or trade mark, any arrangement of lines or grooves may be used within the square to designate the centre of the scored area provided the the additional removed area, when added to the area removed by grooving, as described in Section 1-1 does not exceed in total 25% of the scoring area. Further, the method of scoring as found in Sections 1-1 and 1-2 must be used.
5. The total length of grooves in any one square inch of surface area cannot exceed fourteen inches. The vertical grooves found to right and left of the scored area and the grooves which mark the centre of the scored area shall not be counted to make the fourteen inches of length.
6. The face of the club shall be smooth and flat over the full surface. No sharp edges or lips due to die impression of any type will be permitted. For decorative purposes only, it is permissible to sandblast with fine sand.
The above conditions for smoothness apply also to Sections 2 and 3.

Section 2
1. If punch markings are used instead of grooves, the removed area cannot exceed 18%; i.e. 82% of the scored area must remain after the depressions have been made. The maximum diameter of circular punch marks cannot exceed .075 inch and must be so adjusted that the total area of all punch marks cannot exceed 18% of the scored area. (See Figure 3). The punch markings shall be spaced uniformly over the scored area. No concentration of punch markings in the scored areas will be permitted.
If punch markings are not circular they shall be acceptable if the maximum width is not greater than 1.25 the maximum allowable diameter for circular punch marks. Further the boundary length of non-circular punch marks cannot exceed 3.75 times the maximum allowable diameter for punch marks.
The scored area shall be considered as that portion between the outer vertical lines shown in Fig 3. If no vertical lines are used, the scored area shall be determined by adding the distance between the centreline of the two holes (X) to the distance between the outer centrelines of the punch mark and multiplying this imaginary distance by the average width of the iron.
2. Punch marks shall be essentially uniform and symmetrical in the plane of the face of the club. The centreline of all punch marks shall be normal to the hitting face.
The punch marking may be conical or circular in cross section. If a conical cross-section is used, the included angle (apex) cannot be less than 90 degrees. If a circular cross-section is used, the depth of penetration cannot be greater than the radius of the circle.
Section 3
If grooves and punch marks are used in combination, the total removed area cannot exceed 25% of the area reserved for scoring; the shortest distance between the centreline of any two adjacent punch marks must be 2.5 the diameter of the punch mark. (See X and R of Figure 3) The minimum distance on the surface of the club between the edges of the groove shall be .075 inch, and further, only fourteen inches of grooves may be used in any one square inch of scored surface.
Rule 2-2f
Following are examples of grips which have been approved and some which have been disapproved:-

Appendix I
a. Existence of mud.Note: The play of a provisional ball will automatically disallow the procedure under Rule 33-2 or 33-3.
b. Accumulation of leaves.
c. Unusual damage to course.
d. Local conditions which could be held to interfere with the proper playing of the Game. If this necessitates modification of a Rule of Golf the approval of the Governing Authority must be obtained.
e. Conditions which make a Local Rule necessary for the preservation of the course; this includes prohibition, where necessary, of playing a ball lying in ground under repair.
f. Obstructions, their limits and the extent of relief if the application of Rule 31 is impracticable or inequitable.
g. Any construction which the Committee considers an integral part of the course (Def. 20d), and defines as not an obstruction.
h. Subject to the approval of the Governing Authority, permitting play of a provisional ball for a ball which may be in a water hazard of such character that it would be impracticable to determine whether the ball is in the hazard or to do so would unduly delay play.
2. Frame regulations governing Priority on the Course.
3. Frame regulations governing practice during stroke competitions. (Rules 8-3, 36-4b.)
Rule 2-2d provides in part:
"Club faces shall not have any lines, dots or other markings with sharp or rough edges, or any type of finish, for the purpose of unduly influencing the movement of the ball. Markings on the face of a club shall conform with the specifications."
Sharp or rough edges of markings may be determined by a finger test. A different problem is presented, however, by the detailed Specifications for Markings on Clubs. These are manufacturing specifications. For the guidance of players and Committees, following are a layman's interpretation of some essential parts of the specifications:
In general it is required that the face of a club shall present a smooth, flat
surface on which a limited percentage of the area may be depressed by markings.
When the depressed area is in the form of grooves, each groove may not be wider than .035 inches (approximately one thirty-second of an inch, 0.889m), the angle between the flat surface of the club face and the side of the groove may not be less than 135 degrees. Except as provided elsewhere, the distance between grooves may not be less than three times the width of the groove.
When the depressed area is in the form of punch marks, the markings must not exceed a slight amount over one-sixteenth of an inch (1.6mm) in diameter.
The complete specifications follow:-
Specifications
In general a definite area of the surface is reserved for scoring. All the sections contained in this specification shall refer to this particular scored area. With regard to an iron club, reasonably-sized areas of the heel and the toe shall not be scored - see illustration of "Golf Head Scorings". This restriction does not apply to wood clubs.
This specification is divided into three sections: Section 1 refers to golf clubs where grooves are used; Section 2 refers to golf clubs scored with punch marks; Section 3 includes a combination of groove and punch markings.
Section 1-a Wood Clubs
On wood clubs scoring designs are unrestricted provided the loft or face angle does not exceed 24 degrees. Where the loft or face angle is greater than 24 degrees, the specifications for iron clubs (Section 1-b) shall apply.
Section 1-b Iron Clubs
1. A series of straight grooves in the form of V's may be put in the face of the club. The side walls of the grooves shall be essentially flat and the included angle shall be equal to or greater than 90 degrees. The bisector of the angle shall be normal to the face of the club (see Figure C).
2. The width of a groove shall be generally consistent and not exceed .035 inches (0.889mm) along its full length. This width shall be measured in the plane of the face of the club between the two points where the planes of the groove meet the face of the club.
3. At no place on the face of the club shall the distances between edges of the grooves be less than three times the width of the grooves, i.e., 25% of the area reserved for scoring may be grooved. In the event that grooves are used with a width less than .025 inch (0.635mm), the minimum distance between the edges of the grooves shall be .075 inches (1.905mm).
The scored area shall be considered as that portion between the outer vertical lines shown in Figure C. If only two vertical lines are used and these lines intersect the grooves, it shall be permissible to add to the length of the groove the distance between three grooves (2W) in determining the scored area. In no case can the total length be greater than 2W plus the length of the groove. The total length multiplied by the average width shall be the scored area.
The area of metal or material removed from the vertical lines or grooves shall not be counted in determining the percentage of area scored.
4. The centre of the scored area may be indicated by any design provided it does not exceed the boundary set up by a square whose sides are 0.375 inch (9.525mm). (See Figure 1). If manufacturers have no particular design or trade mark, any arrangement of lines or grooves may be used within the square to designate the centre of the scored area provided the the additionally removed area, when added to the area removed by grooving, as described in Section 1-1 does not exceed in total 25% of the scoring area. Further, the method of scoring as found in Sections 1-1 and 1-2 must be used.
5. The total length of grooves in any one square inch of surface area cannot exceed fourteen inches (55mm per square cm). The vertical grooves found to right and left of the scored area and the grooves which mark the centre of the scored area shall not be counted to make the fourteen inches (55mm) of length.
6. The face of the club shall be smooth and flat over the full surface. No sharp edges or lips due to die impression of any type will be permitted. For decorative purposes only, it is permissible to sandblast with fine sand.
The above conditions for smoothness apply also to Sections 2 and 3.
Section 2
1. If punch markings are used instead of grooves, the removed area cannot exceed 18%; i.e. 82% of the scored area must remain after the depressions have been made. The maximum diameter of circular punch marks cannot exceed .075 inch (1.905mm) and must be so adjusted that the total area of all punch markings does not exceed 18% of the scored area. (See Figure 3). The punch markings shall be spaced uniformly over the scored area. No concentration of punch markings in the scored areas will be permitted.
If punch markings are not circular they shall be acceptable if the maximum width is not greater than 1.25 the maximum allowable diameter for circular punch marks. Further the boundary length of non-circular punch marks cannot exceed 3.75 times the maximum allowable diameter for punch marks.
The scored area shall be considered as that portion between the outer vertical lines shown in Fig 3. If no vertical lines are used, the scored area shall be determined by adding the distance between the centreline of the two holes (X) to the distance between the outer centrelines of the punch mark and multiplying this imaginary distance by the average width of the iron.
2. Punch marks shall be essentially uniform and symmetrical in the plane of the face of the club. The centreline of all punch marks shall be normal to the hitting face.
The punch marking may be conical or circular in cross section. If a conical cross-section is used, the included angle (apex) cannot be less than 90 degrees. If a circular cross-section is used, the depth of penetration cannot be greater than the radius of the circle.
Section 3
If grooves and punch marks are used in combination, the total removed area cannot exceed 25% of the area reserved for scoring; the shortest distance between the centreline of any two adjacent punch marks must be 2.5 the diameter of the punch mark. (See X and R of Figure 3) The minimum distance on the surface of the club between the edges of the groove shall be .075 inch (1.905mm), and further, only fourteen inches (350mm) in any one square inch (6.45 square cm) of scored surface may be used, i.e., 55mm of grooves may be used in any one square centimetre of surface.
Rule 2-2f
Following are examples of grips which have been approved and some which have been disapproved:-

Appendix I
Local Rules
Committees in charge of courses shall, when considered necessary,
1. Make Local Rules for such abnormal conditions as:-
a. Existence of mud.1980 only: In such case, if a provisional ball is played and the original ball is in the water hazard, the player may play the original ball as it lies or continue with the provisional ball in play, but he may not proceed under Rule 33-2 or Rule 33-3.
b. Accumulation of leaves.
c. Unusual damage to course.
d. Stones in bunkers.
e. Other local conditions which could be held to interfere with the proper playing of the Game. If this necessitates modification of a Rule of Golf the approval of the Governing Authority must be obtained.
f. Conditions which make a Local Rule necessary for the preservation of the course; this includes prohibition, where necessary, of playing a ball lying in ground under repair.
g. Obstructions, their limits and the extent of relief if the application of Rule 31 is impracticable or inequitable.
h. Any construction which the Committee considers an integral part of the course (Def. 20c), and defines as not an obstruction.
i. Subject to the approval of the Governing Authority, permitting play of a provisional ball for a ball which may be in a water hazard of such character that it would be impracticable to determine whether the ball is in the hazard or to do so would unduly delay play.
2. Frame regulations governing Priority on the Course.
3. Frame regulations governing practice during stroke competitions. (Rules 8-3, 36-4b.)
Design of Clubs (Def. 36)
Rule 2-2a provides in part:
"The golf club shall be composed of a shaft and a head, and all of the various parts shall be fixed so that the club is one unit; the club shall not be designed to be adjustable, except for weight.
Note: Playing characteristics not to be changed during a round - Rule 2-2b.
The club shall not be substantially different from the traditional and customary form and make, and shall conform with the regulations governing the design of clubs."
The following are the regulations governing the design of clubs:-
a. Shape of Head
The length of a clubhead shall be greater than the breadth.
Length shall be determined on a horizontal line, 0.625 inches (16mm) above the sole, from the back of the heel to the end of the toe or a vertical projection thereof.
Breadth shall be determined on a horizontal line between the outermost points of the face and the back of the head or vertical projections thereof.
b. Face of Head
The club shall have only one face designed for striking the ball, except that a putter may have two faces if the loft of both faces is substantially the same and does not exceed ten degrees.
Club faces shall not embody any degree of concavity on the hitting surface.
Club faces shall not have any lines, dots or other markings with sharp or rough edges, or any type of finish, for the purpose of unduly influencing the movement of the ball.
Markings on the face of a club shall conform with the specifications in Appendix III.
The face of an iron club shall not contain an inset or attachment.
c. Shaft
The shaft shall be designed to be straight from the top to a point not more than 5 inches (127mm) above the sole. The shaft, including any inserted plug, shall be generally circular in cross-section and shall extend to the upper end of the grip.

The shaft shall be fixed to the clubhead at the heel (as illustrated in Figure A). The shaft may be attached directly to the clubhead or to a neck or socket of the clubhead; any neck or socket shall not be more than 5 inches (127mm) in length measured from the top of the neck or socket to the sole. The shaft and the neck or socket shall remain in line with the heel, or with a point to right or left of the heel, when the club is soled at address. The distance between the axis of the shaft (or the neck or socket) and the back of the heel shall not exceed 0.625 inches (16mm) in wood clubs and 0.3125 inches (8mm) in iron clubs.
Exception for Putters: The shaft or neck or socket of a putter may be fixed at any point in the head and need not remain in line with the heel. The axis of the shaft from the top to a point not more than 5 inches (127mm) above the sole shall diverge from the vertical by at least ten degrees in relation to the horizontal line determining length of head under Appendix IIa. The shaft in cross-section shall be generally circular or otherwise symmetrical.
d. Grip
The grip consists of that part of the shaft designed to be held by the player and any material added to it for the purpose of obtaining a firm hold. The grip shall be substantially straight and plain in form, may have flat sides, but shall not have a channel or furrow or be moulded for any part of the hands (see Figure B).
Figure B - The following are examples of grips which have been approved and some which have been disapproved

Rule 2-2a provides in part:
"The golf club shall be composed of a shaft and a head, and all of the various parts shall be fixed so that the club is one unit; the club shall not be designed to be adjustable, except for weight.
Note: Playing characteristics not to be changed during a round - Rule
2-2b.
The club shall not be substantially different from the traditional and customary form and make, and shall conform with the regulations governing the design of clubs at Appendix II and the specifications for markings on clubs."
Appendix IIb provides in part:
"Club faces shall not have any lines, dots or other markings with sharp or rough edges, or any type of finish, for the purpose of unduly influencing the movement of the ball. Markings on the face of a club shall conform with the specifications."
Sharp or rough edges of markings may be determined by a finger test. A different problem is presented, however, by the detailed Specifications for Markings on Clubs. These are manufacturing specifications. For the guidance of players and Committees, following are a layman's interpretation of some essential parts of the specifications:
In general it is required that the face of a club shall present a smooth, flat
surface on which a limited percentage of the area may be depressed by markings.
When the depressed area is in the form of grooves, each groove may not be wider than .035 inches (approximately one thirty-second of an inch) (0.9mm), the angle between the flat surface of the club face and the side of the groove may not be less than 135 degrees. Except as provided elsewhere, the distance between grooves may not be less than three times the width of the groove.
When the depressed area is in the form of punch marks, the markings must not exceed .075 inches (a little over one-sixteenth of an inch) (1.9mm) in diameter.
The complete specifications are:-
Specifications
In general a definite area of the surface is reserved for scoring. All the sections contained in this specification shall refer to this particular scored area. With regard to an iron club, reasonably-sized areas of the heel and the toe shall not be scored - see illustration of "Golf Head Scorings" in Figure C. This restriction does not apply to wood clubs.
This specification is divided into three sections: Section 1 refers to golf clubs where grooves are used; Section 2 refers to golf clubs scored with punch marks; Section 3 includes a combination of groove and punch markings.
Section 1-a Wood Clubs
Wood clubs shall not have any markings on the face for the purpose of unduly influencing the movement of the ball. Where the loft or face angle exceeds 24 degrees, grooves shall be generally straight with a maximum width measured in the face plane of .040 inches (1mm). The depth of any groove shall not be greater than 1½ times the width. At no place on the face shall the distance between the edges of the grooves be less than three times the width of the adjacent groove.
Section 1-b Iron Clubs
1. A series of straight grooves in the form of V's may be put in the face of the club. The side walls of the grooves shall be essentially flat and the included angle shall be equal to or greater than 90 degrees. The bisector of the angle shall be normal to the face of the club (see illustration of 'Golf Head Scorings' in Figure C).

2. The width of a groove shall be generally consistent and not exceed .035 inches (0.9mm) along its full length. This width shall be measured in the plane of the face of the club between the two points where the planes of the groove meet the face of the club. The widths of grooves in any club face shall be generally consistent.
3. At no place on the face of the club shall the distances between edges of the grooves be less than three times the width of a groove, with the minimum distance between the edges of any two grooves being .075 inches (1.9mm).
4. Lines may be used to define the toe, heel and top boundaries of the scored area. Such a line must be no wider or deeper than .040 inches (1mm). Designs may be used to indicate the toe and heel boundaries of the scored area. They must be no deeper than .040 inches (1mm). Designs and lines must have smooth edges and shall not be designed in any way to influence unduly the movement of the ball.
5. The scored area shall be considered as that portion of the face within boundary lines or designs. In the case where such lines or designs do not exist, the scored area shall be that portion between the extremities of the grooves.
6. The centre or intended impact centre of the face may be indicated by a design which shall fit within the boundary of a square whose sides are 0.375 inches (9.5mm) in length. Such a marking shall not in anyway be designed to influence unduly the movement of the ball.
7. The face of the club shall be smooth and flat over the full surface. No sharp edges or lips due to die impression of any type will be permitted. For decorative purposes only, it is permissible to sandblast the scored area not to exceed a roughness of 180 micro inches (4.6 microns), with 15% tolerance. The relative roughness shall be determined in accordance with British standards for surface texture. The direction of measurement shall be parallel to the grooves.
The above conditions for smoothness apply also to Sections 2 and 3.
Section 2
Punch marks may be used in the place of grooves. The area of such a mark, in the plane of the face, may not exceed .0044 square inches (2.8 sq mm). A mark may not be closer to an adjacent mark than 0.168 inches (4.3mm) measured from centre to centre. The depth of a mark may not be greater than .038 inches (1mm) with centre line normal to the face. Punch marks must be evenly distributed throughout the scored area.
Section 3
In the event punch marks in combination with grooves are used within the scored area, groove specifications govern as in Section 1 if grooves are adjacent. Punch mark specifications govern if punch marks are adjacent. At no place may a punch mark be closer to a groove measured from centre to centre than 0.168 inches (4.3mm).
Appendix I
LOCAL RULES (RULE 33-8) AND CONDITIONS OF THE COMPETITION (RULE 33-1)
1. The Committee may make and publish Local Rules (for Specimen Local Rules see Part B) for such abnormal conditions as:
a. Obstructions
Stipulating the limits of obstructions and the extent of relief if the application of Rule 24 is impracticable or inequitable.
Clarifying the status of objects which may be obstructions (Rule 24).
Declaring any construction to be an integral part of the course and, accordingly, not an obstruction, e.g. artificial surfaces and sides of roads and paths.
Providing relief from fixed sprinkler heads within two club-lengths of the putting green.
(Tournament Local Rules for Temporary Obstructions are available from the Royal and Ancient golf Club of St Andrews.)
b. Stones in Bunkers
Allowing the removal of stones in bunkers by declaring them to be
movable obstructions.
c. Areas Requiring preservation
Declaring such areas "ground under repair" and prohibiting play thereon.
d. Unusual Damage to the Course or Accumulation of Leaves (or the Like)
Declaring such areas "ground under repair" (Rule 25.)
Note: Relief from an accumulation of leaves, etc. which is seasonal must be temporary and the Local Rule withdrawn as soon as possible.
e. Extreme Wetness, Mud, Poor Conditions and Protection of Course
(i) Lifting an Embedded Ball, Cleaning
Where the ground is unusually soft, the Committee may, by Local Rule, allow the lifting of a ball which is embedded in its own pitch-mark in an area "through the green" which is not "closely mown" (Rule 25-2) if it is satisfied that the proper playing of the game would otherwise be prevented. The Local Rule shall be for that day only or for a short period, and if practicable shall be confined to specified areas. The Committee shall withdraw the Local Rule as soon as conditions warrant and should not print it on the score card.
In similarly adverse conditions, the Committee may, by temporary local Rule, permit the cleaning of a ball "through the green".
(ii) "Preferred Lies" and "Winter Rules"
Adverse conditions, including the poor condition of the course or the existence of mud, are sometimes so general, particularly during winter months, that the Committee may decide to grant relief by Local Rule either to protect the course or to promote fair and pleasant play. Such Local Rule shall be withdrawn as soon as conditions warrant.
f. Other Local Conditions which Interfere with the Proper Playing of the Game
If this necessitates modification of a Rule of Golf the approval of the Governing Authority must be obtained.
g. Dropping Zones
Where it is not feasible or practicable to proceed in conformity with Rule 24-2b (Immovable Obstruction), Rule 26 (Water Hazards including Lateral Water Hazards) or Rule 28 (Ball Unplayable) the Committee may establish special zones in which balls may or shall be dropped when relief is taken.
h. Provisional Ball for Ball in Water Hazard
Subject to the approval of the Governing Authority, the Committee may permit play of a provisional ball for a ball which may be in a water hazard of such character that it would be impracticable to determine whether the ball is in the hazard or to do so would unduly delay play. In such case, if a provisional ball is played, and the original ball is in the water hazard, the player may play the original ball as it lies or continue the provisional ball in play, but he may not proceed under Rule 26-1.
2. Practice
The Committee may make regulations governing Practice under Rules 7 and
33-2c.
3. Priority on the Course
The Committee may make regulations governing Priority on the Course (see Etiquette).
4. Specification of the Ball
See Note 2 to Rule 5-1.
5. Time of Starting
See Note to Rule 6-3a.
6. Advice in Team Competitions
See Note to Rule 8-1.
Within the policy set out in part A of this Appendix the Committee may adopt a Specimen Local Rule by referring, on a score card or notice board, to the examples given below. However, Specimen Local Rules 4 or 5 should not be printed or referred to on a score card as they are both of limited duration.
1. Fixed Sprinkler Heads
All fixed sprinkler heads are immovable obstructions and relief from interference by them may be obtained under Rule 24-2. In addition, if such an obstruction on or within two club-lengths of the putting green of the hole being played intervenes on the line of play between the ball and the hole, the player may obtain relief, without penalty, as follows:
If the ball lies off the putting green but not in a hazard and is within two club-lengths of the intervening obstruction , it may be lifted, cleaned and dropped at the nearest point to where the ball lay which (a) is not nearer the hole, (b) avoids such intervention and (c) is not in a hazard or on a putting green.
PENALTY FOR BREACH OF LOCAL RULE:
Match play - Loss of hole; Stroke play - Two strokes
2. Stones in bunkers
Stones in bunkers are movable obstructions. Rule 24-1 applies.
3. Areas Requiring Preservation
In any area of "ground under repair" from which play is prohibited , the player shall not play his ball from, or take his stance in, such ground. He must take relief under Rule 25-1b.
PENALTY FOR BREACH OF LOCAL RULE:
Match play - Loss of hole; Stroke play - Two strokes.
4. Lifting an Embedded Ball
(Specify the area if practicable)... through the green, a ball embedded in its own pitch-mark in ground other than sand may be lifted, cleaned and dropped, without penalty, as near as possible to the spot where it lay but not nearer the hole.
PENALTY FOR BREACH OF LOCAL RULE:
Match play - Loss of hole; Stroke play - Two strokes.
5. "Preferred Lies" and "Winter Rules"
A ball lying on any "closely mown area" through the green may, without penalty, be moved or may be lifted, cleaned and placed within six inches of where it originally lay, but not nearer the hole. After the ball has been so moved or placed, it is in play, and if it moves after the player has addressed it, the penalty shall be one stroke - See Rule 18-2b.
PENALTY FOR BREACH OF LOCAL RULE:
Match play - Loss of hole; Stroke play - Two strokes.
Any design in a club or ball which is not covered by Rules 4 and 5 and Appendices II and III, or which might significantly change the nature of the game, will be ruled on by the Royal and Ancient Golf Club of St Andrews and the United States Golf Association.
Note: Equipment approved for use or marketed prior to January 1st, 1984 which conforms to the Rules in effect in 1983 but does not conform to the 1984 Rules may be used until December 31st, 1989; thereafter all equipment must conform to the current Rules.
Rule 4-1 prescribes general regulations for the design of clubs. The following paragraphs, which provide some specifications and clarify how Rule 4-1 is interpreted, should be read in conjunction with that Rule.
Editor's Note: In two publications I have seen for this period, there is no part "4-1a" here. Deliberate, or an error?
4-1b. Shaft
Generally Straight. The shaft must be straight from the top of the grip to a point not more than 5 inches (127mm) above the sole, measured along the axis of the shaft and the neck or socket.
Bending and Twisting Properties. The shaft must be so designed and manufactured that at any point along its length:
(i) it bends in such a way that the deflection is the same regardless of how the shaft is rotated about its longitudinal axis; and
(ii) twist the same amount in both directions.
Attachment to Clubhead. The neck or socket must not be more than 5 inches (127mm) in length, measured from the top of the neck or socket to the sole along its axis. The shaft and the neck or socket must remain in line with the heel, or with a point to the right or left of the heel, when the club is viewed in the address position. The distance between the axis of the shaft or the neck or socket and the back of the heel must not exceed 0.625 inches (16mm).
Exception for Putters: The shaft or neck or socket of a putter may be fixed at any point in the head and need not remain in line with the heel. The axis of the shaft from the top to a point not more than 5 inches (127mm) above the sole must diverge from the vertical in the toe-heel plane by at least 10 degrees in relation to the horizontal line determining length of head under Appendix II, Clubhead.
4-1c. Grip (see diagram)
(i) For clubs other than putters the grip must be generally circular in cross-section, except that a continuous, straight,
slightly raised rib may be incorporated along the full length of the grip.
(ii) A putter grip may have a non-circular cross-section, provided the cross-section has no concavity, is symmetrical
and remains generally similar throughout the length of the grip.
(iii) The grip may be tapered but must not have any bulge or waist.
(iv) The axis of the grip must coincide with the axis of the shaft, except for a putter.
4-1d. Clubhead
Dimensions. The length and the breadth of a clubhead are
measured on horizontal lines between vertical projections of the extremities when the clubhead is soled in its normal address position. If the heel extremity is not clearly defined, it is deemed to be 0.625 inches (16mm) above the sole.
Plain in Shape. Features such as fins or holes are not permitted, but certain exceptions may be made for putters. Any furrows or runners shall not extend into the face. Windows, holes or transparencies for the purpose of aiding the player in positioning himself are not permitted.
4-1e. Club Face
Hardness and Rigidity. The club face must not be designed and manufactured to have the effect at impact of a spring which would unduly influence the movement of the ball.
Markings. Except for specified markings, the surface roughness must not exceed that of decorative sandblasting. Markings must not have sharp edges or raised lips, as determined by a finger test. Markings within the area where impact is intended (the "impact area") are governed by the following:
(i) Grooves. A series of straight grooves with diverging sides and a symmetrical cross-section may be used (see diagram). The width of grooves must be generally consistent and not exceed 0.035 inches (0.9mm) along their length. The distance between edges of adjacent grooves must not be less than three times the width of a groove and not less than 0.075 inches (1.9mm). The depth of a groove must not exceed 0.020 inches (0.5mm).
(ii) Punch Marks. Punch marks may be used. The area of any such mark must not exceed 0.0044 square inches (2.8 sq.mm). A mark must not be closer to an adjacent mark than 0.168 inches (4.3mm) measured from centre to centre. The depth of a punch mark must not exceed 0.040 inches (1.0mm). If punch marks are used in combination with grooves, a punch mark must not be closer to a groove than 0.168 inches (4.3mm), measured from centre to centre.
Decorative Markings. The centre of the impact area may be indicated by a design within the boundary of a square whose sides are 0.375 inches (9.5mm) in length. Such a design must not unduly influence the movement of the ball. Markings outside the impact area must not be greater than 0.040 inches (1.00mm) in depth and width.
Non-metallic Club Face Markings. The above specifications for markings do not apply to non-metallic clubs with loft angles less than 24 degrees, but markings which could unduly influence the movement of the ball are prohibited. Non-metallic clubs with a loft or face angle exceeding 24 degrees may have grooves of maximum width 0.040 inches (1.00mm) and maximum depth 1½ times the groove width, but must otherwise conform to the markings specifications above.
a. Weight
The weight of the ball shall not be greater than 1.620 ounces avoirdupois (45.93gm).
b. Size
The diameter of the ball shall be not less than 1.620 inches
(41.15mm). This specification will be satisfied if, under its own
weight, a ball falls through a 1.620 inches diameter ring gauge in
fewer than 25 out of 100 randomly selected positions, the test being
carried out at a temperature of 23 ±1°C.
Note: The Rules of the United States Golf Association specify a minimum diameter of 1.680 inches (42.67mm) and apply an Overall Distance Standard
c. Spherical Symmetry
The ball shall be designed and manufactured to perform in general as if it were spherically
symmetrical.
As outlined in procedures on file at the Royal and Ancient Golf Club of St Andrews and the United States Golf Association, differences in peak angle of trajectory, carry and time of flight will be measured when 40 balls of the same type are launched, spinning 20 about one axis and 20 about another axis.
These tests will be performed using apparatus approved by the Royal and Ancient Golf Club of St Andrews and the United States Golf Association. If in two successive tests differences in the same two or more measurements are statistically significant at the 5% level of significance and exceed the limits set forth below, the ball type will not conform to the symmetry specification.
| Measurement | Maximum Absolute Difference of the Means |
| Peak angle of trajectory Carry distance Flight time |
0.9 grid units (approx 0.4 degrees) 2.5 yards 0.16 seconds |
d. Initial Velocity
The velocity of the ball shall not be greater than 250 feet
(76.2m) per second when measured on apparatus approved by the Royal
and Ancient Golf Club of St. Andrews. A maximum tolerance of 2% will
be allowed. The temperature of the ball when tested shall be 23 ±1°C.
e. Overall Distance Standard
A brand of golf ball, when tested on apparatus approved by the
Royal and Ancient Golf Club of St. Andrews under the conditions set
forth in the Overall Distance Standard for golf balls on file with
the Royal and Ancient Golf Club of St. Andrews, shall not cover an
average distance in carry and roll exceeding 280 yards (256 metres)
plus a tolerance of 6%.
Note: The 6% tolerance will be reduced to a minimum of 4% as test techniques are improved.
Notes to Appendix III
1. The size specified in (b) above will take effect from 1st January 1990. Until that date the previous size specification of a diameter not less than 1.620 inches (41.15mm) will apply.
2. The Overall Distance Standard will apply only to balls which meet the new size specification of a diameter not less than 1.680 inches (42.67mm).
3. In international team competitions, until 31st December, 1989, the previous size specification of a diameter not less than 1.620 inches (41.15mm) will apply.
1. Obstructions
a. General
b. Stones in Bunkers
Allowing the removal of stones in bunkers by declaring them to be
"movable obstruction" (Rule 24).
c. Roads and Paths
(i) Declaring artificial surfaces and sides of roads and paths to
be integral parts of the course, or
(ii) Providing relief of the type afforded under
Rule 24-2b from roads and paths not
having artificial surfaces and sides if they could unfairly affect
play.
d. Fixed Sprinkler Heads
Providing relief from intervention by fixed sprinkler heads within
two club-lengths of the putting green when the ball lies within two
club-lengths of the sprinkler head.
e. Temporary Obstructions
Specimen Local Rules for application in Tournament
Play are available from the Royal and Ancient Golf Club of St.
Andrews.
Assisting preservation of the course by defining areas, including turf nurseries, young plantations and other parts of the course under cultivation, as "ground under repair" from which play is prohibited.
3. Unusual Damage to the Course or Accumulation of Leaves (or the like)Declaring such areas to be "ground under repair" (Rule 25). The Committee may, by Local Rule, deny relief from interference with a player's stance by such areas - see Note to Rule 25-1a.
Note: For relief from aeration holes see Specimen Local Rule 7 in Part B of this Appendix.
4. Extreme Wetness, Mud, Poor Conditions and Protection of Course
a. Lifting an Embedded Ball, Cleaning
Where the ground is unusually soft, the Committee may, by
temporary Local Rule, allow the lifting of a ball which is embedded
in its own pitch-mark in the ground in an area "through the green"
which is not "closely mown" (Rule 25-2)
if it is satisfied that the proper playing of the game would
otherwise be prevented. The Local Rule shall be for that day only or
for a short period, and if practicable shall be confined to specified
areas. The Committee shall withdraw the Local Rule as soon as
conditions warrant and should not print it on the score card.
In similarly adverse conditions, the Committee may, by temporary
Local Rule, permit the cleaning of a ball "through the green".
b. "Preferred Lies" and "Winter Rules"
Adverse conditions, including the poor condition of the course or
the existence of mud, are sometimes so general, particularly during
winter months, that the Committee may decide to grant relief by
temporary Local Rule either to protect the course or to promote fair
and pleasant play. Such Local Rule shall be withdrawn as soon as
conditions warrant.
If this necessitates modification of a Rule of Golf the approval of the Governing Authority must be obtained.
Other matters which the Committee could cover by Local Rule
include:
a. Lateral Water Hazards
Clarifying the status of sections of water hazards which may be
lateral water hazards (Rule 26)
b. Provisional Ball
Permitting play of a provisional ball for a ball which may be in a
water hazard of such character that it would be impracticable to
determine whether the ball is in the hazard or to do so would unduly
delay play. In such a case, if a provisional ball is played and the
original ball is in a water hazard, the player may play the original
ball as it lies or continue the provisional ball in play, but he may
not proceed under Rule 26-1.
Specifying means used to define out of bounds, hazards, water hazards, lateral water hazards and ground under repair.
8. Dropping ZonesEstablishing special areas in which balls may or shall be dropped when it is not feasible or practicable to proceed exactly in conformity with Rule 24-2b (Immovable Obstruction), Rule 25-1b or Rule 25-1c (Ground Under Repair), Rule 26-1 (Water Hazards and Lateral Water Hazards) or Rule 28 (Ball Unplayable)
9. Priority on the CourseThe Committee may make regulations governing Priority on the Course (see Etiquette)
SPECIMEN LOCAL RULES
Within the policy set out in Part A of this Appendix, the Committee may adopt a Specimen Local Rule by referring, on a score card or notice board, to the examples given below. However, Specimen Local Rules 4, 5 or 6 should not be printed or referred to on a score card as they are all of limited duration.
1. Fixed Sprinkler Heads
All fixed sprinkler heads are immovable obstructions and relief
from interference by them may be obtained under Rule 24-2. In
addition, if such an obstruction on or within two club-lengths of the
putting green of the hole being played intervenes on the line of play
between the ball and the hole, the player may obtain relief, without
penalty, as follows:
If the ball lies off the putting green but not in a hazard and is
within two club-lengths of the intervening obstruction, it may be
lifted, cleaned and dropped at the nearest point to where the ball
lay which (a) is not nearer the hole, (b) avoids such intervention
and (c) is not in a hazard or on a putting green.
PENALTY FOR BREACH OF LOCAL RULE:
Match play - Loss of Hole;
Stroke play - Two strokes.
2. Stones in Bunkers
Stones in bunkers are movable obstructions (Rule 24-1 applies).
3. Ground Under Repair: Play Prohibited
If a player's ball lies in an area of "ground under repair" from
which play is prohibited, or if such an area of "ground under repair"
interferes with the player's stance or the area of his intended swing
the player must take relief under Rule 25-1.
PENALTY FOR BREACH OF LOCAL RULE:
Match play - Loss of hole;
Stroke play - Two strokes.
4. Lifting an Embedded Ball
(Specify the area if practicable) . . . through the green, a ball
embedded in its own pitch-mark in ground other than sand may be
lifted, cleaned and dropped, without penalty, as near as possible to
the spot where it lay but not nearer the hole.
PENALTY FOR BREACH OF LOCAL RULE:
Match play - Loss of hole;
Stroke play - Two strokes.
5. Cleaning Ball
(Specify the area if practicable) ... through the green a ball may
be lifted, cleaned and replaced without penalty.
Note: The position of the ball shall be marked before it is lifted under this Local Rule - see Rule 20-1.
6. "Preferred Lies" and "Winter Rules"
A ball lying on any "closely mown area" through the green may,
without penalty, be moved or may be lifted, cleaned and placed within
six inches of where it originally lay, but not nearer the hole. After
the ball has been so moved or placed, it is in play.
PENALTY FOR BREACH OF LOCAL RULE:
Match play - Loss of hole;
Stroke play - Two strokes.
7. Aeration Holes
If a ball comes to rest in an aeration hole, the player may,
without penalty, lift the ball and clean it. Through the green, the
player shall drop the ball as near as possible to where it lay, but
not nearer the hole. On the putting green, the player shall place the
ball at the nearest spot not nearer the hole which avoids such
situation.
PENALTY FOR BREACH OF LOCAL RULE:
Match play - Loss of hole;
Stroke play - Two strokes.
CONDITIONS OF THE COMPETITION
Rule 33-1 provides, "The Committee shall lay down the conditions
under which a competition is to be played". Such conditions should
include many matters such as method of entry, eligibility, number of
rounds to be played, settling ties, etc. which it is not appropriate
to deal with in the Rules of Golf or this Appendix.
However, there are four matters which might be covered in the
Conditions of the Competition to which the Committee's attention is
specifically drawn by way of a Note to the appropriate Rule. These
are:
Arising from the regulations for ball-testing under Rule 5-1, Lists of Conforming Golf Balls will be issued from time to time.
It is recommended that the Lists should be applied to all National and
County (or equivalent) Championships and to all top-class events when
restricted to low handicap players. In order to apply the Lists to a
particular competition the Committee must lay this down in the
Conditions of the Competition. This should be referred to in the
Entry Form, and also a notice should be displayed on the Club notice
board and at the 1st Tee along the following lines:
...........................(Name of Event)...............................
............................(Date and Club)................................
The ball the player uses shall be named on the current List of Conforming Golf Balls issued by the Royal and Ancient Golf Club of St. Andrews.
Note 1: A penalty statement will be required and must be either:
(a) "PENALTY FOR BREACH OF CONDITION:
Disqualification."
or
(b) "PENALTY FOR BREACH OF CONDITION:
Match play - Loss of each hole at which a breach occurred.
Stroke play - Two strokes for each hole at which a breach
occurred."
If option (b) is adopted this only applies to use of a ball which, whilst not on the List of Conforming Golf Balls, does conform to the specifications set forth in Rule 5 and Appendix III. The penalty for use of a ball which does not so conform is disqualification.
Note 2: In Club events it is recommended that no such condition be applied.
2. Time of Starting (Note to Rule 6-3a)If the Committee wishes to act in accordance with the Note, the
following wording is recommended:
"If, in the absence of circumstances which warrant waiving the penalty of disqualification as provided in Rule 33-7, the player arrives at his starting point, ready to play, within
five minutes after his starting time, the penalty for failure to start on time is loss of the
first hole to be played in match play or two strokes in stroke play."
The Committee may make regulations governing practice in accordance with the Note to Rule 7-1, Exception (c) to Rule 7-2, Note 2 to Rule 7 and Rule 33-2c.
4. Advice in Team CompetitionsIf the Committee wishes to act in accordance with the Note, the following wording is recommended:
"In accordance with the Note to Rule 8-1 of the Rules of Golf each team may appoint one person (in addition to the persons from whom advice may be asked under that Rule) who may give advice to members of that team. Such person [if it is desired to insert any restriction on who may be nominated insert such restriction here] shall be identified to the Committee prior to the start of the Competition."
Any design in a club or ball which is not covered by Rules 4 and 5 and Appendices II and III, or which might significantly change the nature of the game, will be ruled on by the Royal and Ancient Golf Club of St Andrews and the United States Golf Association.
Note: Equipment approved for use or marketed prior to January 1st, 1984 which conforms to the Rules in effect in 1983 but does not conform to the 1984 Rules may be used until December 31st, 1989; thereafter all equipment must conform to the current Rules.
Rule 4-1 prescribes general regulations for the design of clubs. The following paragraphs, which provide some specifications and clarify how Rule 4-1 is interpreted, should be read in conjunction with that Rule.
4-1a. General
Adjustability - Exception for Putters.
Clubs other than
putters shall not be designed to be adjustable except for weight.
Some other forms of adjustability are permitted in the design of a
putter, provided that:
(i) the adjustment cannot be readily made;
(ii) all adjustable parts are firmly fixed and there is no reasonable
likelihood of them working loose during a round; and
(iii) all configurations of adjustment conform with the Rules.
The disqualification penalty for purposely changing the playing
characteristics of a club during a
stipulated round
(Rule 4-2) applies to all clubs
including a putter.
Note: It is recommended that all putters with adjustable parts be submitted to the Royal and Ancient Golf Club of St. Andrews for a ruling.
4-1b. ShaftGenerally Straight. The shaft shall be at least 18 inches (457mm) in length. it shall be straight from the top of the grip to a point not more than 5 inches (127mm) above the sole, measured along the axis of the shaft and the neck or socket.
Bending and Twisting Properties. The shaft must be so designed and manufactured that at any point along its length:
(i) it bends in such a way that the deflection is the same regardless of how the shaft is rotated about its longitudinal axis; and
(ii) twist the same amount in both directions.
Attachment to Clubhead. The neck or socket must not be more than 5 inches (127mm) in length, measured from the top of the neck or socket to the sole along its axis. The shaft and the neck or socket must remain in line with the heel, or with a point to the right or left of the heel, when the club is viewed in the address position. The distance between the axis of the shaft or the neck or socket and the back of the heel must not exceed 0.625 inches (16mm).
Exception for Putters: The shaft or neck or socket of a putter may be fixed at any point in the head and need not remain in line with the heel. The axis of the shaft from the top to a point not more than 5 inches (127mm) above the sole must diverge from the vertical in the toe-heel plane by at least 10 degrees when the club is in its normal address position.
4-1c. Grip
(i) For clubs other than putters the grip must be generally circular
in cross-section, except that a continuous, straight,
slightly raised rib may be incorporated along the full
length of the grip.
(ii) A putter grip may have a non-circular cross-section,
provided the cross-section has no concavity, is symmetrical
and remains generally similar throughout the length of the
grip.
(iii) The grip may be tapered but must not have any bulge or
waist.
(iv) For clubs other than putters the axis of the grip must
coincide with the axis of the shaft.
Dimensions. The dimensions of a clubhead (see diagram) are measured, with the clubhead in its normal address position, on horizontal lines between vertical projections of the outermost points of (i) the heel and the toe and (ii) the face and the back. If the outermost point of the heel is not clearly defined, it is deemed to be 0.625 inches (16mm) above the horizontal plane on which the club is resting in its normal address position.
Plain in Shape. The clubhead shall be generally plain in
shape. All parts shall be rigid, structural in nature and functional.
Features such as holes through the head, windows or transparencies, or appendages to the main body of the head such as plates, rods or fins for the purpose of meeting dimensional specifications, for aiming or for any purpose are not permitted. Exceptions may be made for putters.
Any furrows in or runners on the sole shall not extend into the face.
Hardness and Rigidity. The club face must not be designed and manufactured to have the effect at impact of a spring which would unduly influence the movement of the ball.
Markings. Except for specified markings, the surface roughness must not exceed that of decorative sandblasting. Markings must not have sharp edges or raised lips, as determined by a finger test. Markings within the area where impact is intended (the "impact area") are governed by the following:
(i) Grooves. A series of straight grooves with diverging sides and a symmetrical cross-section may be used (see diagram). The width and cross-section must be consistent across the face of the club and along the length of the grooves. Any rounding of groove edges shall be in the form of a radius which does not exceed 0.020 inches (0.5mm). The width of the grooves shall not exceed 0.035 inches (0.9mm), using the 30 degree method of measurement on file with the Royal and Ancient Golf Club of St. Andrews. The distance between edges of adjacent grooves must not be less than three times the width of a groove, and not less than 0.075 inches (1.9mm). The depth of a groove must not exceed 0.020 inches (0.5mm).
(ii) Punch Marks. Punch marks may be used. The area of any such mark must not exceed 0.0044 square inches (2.8 sq.mm). A mark must not be closer to an adjacent mark than 0.168 inches (4.3mm) measured from centre to centre. The depth of a punch mark must not exceed 0.040 inches (1.0mm). If punch marks are used in combination with grooves, a punch mark must not be closer to a groove than 0.168 inches (4.3mm), measured from centre to centre.
Decorative Markings. The centre of the impact area may be indicated by a design within the boundary of a square whose sides are 0.375 inches (9.5mm) in length. Such a design must not unduly influence the movement of the ball. Markings outside the impact area must not be greater than 0.040 inches (1.00mm) in depth and width.
Non-metallic Club Face Markings. The above specifications for markings do not apply to non-metallic clubs with loft angles less than 24 degrees, but markings which could unduly influence the movement of the ball are prohibited. Non-metallic clubs with a loft or face angle exceeding 24 degrees may have grooves of maximum width 0.040 inches (1.00mm) and maximum depth 1½ times the groove width, but must otherwise conform to the markings specifications above.
[go back ]
b. Size
The diameter of the ball shall be not less than 1.680 inches
(42.67mm). This specification will be satisfied if, under its own
weight, a ball falls through a 1.680 inches diameter ring gauge in
fewer than 25 out of 100 randomly selected positions, the test being
carried out at a temperature of 23 ±1°C.
c. Spherical Symmetry
The ball shall be designed and manufactured to perform in general as if it were spherically
symmetrical.
As outlined in procedures on file at the Royal and Ancient Golf Club of St Andrews, differences in peak angle of trajectory, carry and time of flight will be measured when 40 balls of the same type are launched, spinning 20 about one axis and 20 about another axis.
These tests will be performed using apparatus approved by the Royal and Ancient Golf Club of St Andrews. If in two successive tests differences in the same two or more measurements are statistically significant at the 5% level of significance and exceed the limits set forth below, the ball type will not conform to the symmetry specification.
| Measurement | Maximum Absolute Difference of the Means |
| Peak angle of trajectory Carry distance Flight time |
0.9 grid units (approx 0.4 degrees) 2.5 yards 0.16 seconds |
d. Initial Velocity
The velocity of the ball shall not be greater than 250 feet
(76.2m) per second when measured on apparatus approved by the Royal
and Ancient Golf Club of St. Andrews. A maximum tolerance of 2% will
be allowed. The temperature of the ball when tested shall be 23
±1°C.
e. Overall Distance Standard
A brand of golf ball, when tested on apparatus approved by the
Royal and Ancient Golf Club of St. Andrews under the conditions set
forth in the Overall Distance Standard for golf balls on file with
the Royal and Ancient Golf Club of St. Andrews, shall not cover an
average distance in carry and roll exceeding 280 yards (256 metres)
plus a tolerance of 6%.
Note: The 6% tolerance will be reduced to a minimum of 4% as test techniques are improved.
Notes to Appendix III
1. The size specified in (b) above will take effect from 1st January 1990. Until that date the previous size specification of a diameter not less than 1.620 inches (41.15mm) will apply.
2. The Overall Distance Standard will apply only to balls which meet the new size specification of a diameter not less than 1.680 inches (42.67mm).
3. In international team competitions, until 31st December, 1989, the previous size specification of a diameter not less than 1.620 inches (41.15mm) will apply.
Appendix I
LOCAL RULES (RULE 33-8) AND CONDITIONS OF THE COMPETITION (RULE 33-1)
1. Obstructions
a. General
Clarifying the status of objects which may be obstructions
(Rule 24).
Declaring any construction to be an integral part of the course and,
accordingly, not an obstruction, e.g. built-up sides of teeing
grounds, putting greens and bunkers (Rule 24
and Rule 33-2a).
b. Stones in Bunkers
Allowing the removal of stones in bunkers by declaring them to be
"movable obstruction" (Rule 24).
c. Roads and Paths
(i) Declaring artificial surfaces and sides of roads and paths to
be integral parts of the course, or
(ii) Providing relief of the type afforded under
Rule 24-2b from roads and paths not
having artificial surfaces and sides if they could unfairly affect
play.
d. Fixed Sprinkler Heads
Providing relief from intervention by fixed sprinkler heads within
two club-lengths of the putting green when the ball lies within two
club-lengths of the sprinkler head.
e. Protection of Young Trees
Providing relief for the protection of young trees.
f. Temporary Obstructions
Specimen Local Rules for application in Tournament
Play are available from the Royal and Ancient Golf Club of St.
Andrews.
2. Areas of the Course Requiring Preservation
Assisting preservation of the course by defining areas, including turf nurseries, young plantations and other parts of the course under cultivation, as "ground under repair" from which play is prohibited.
3. Unusual Damage to the Course or Accumulation of Leaves (or the like)
Declaring such areas to be "ground under repair" (Rule 25).
Note: For relief from aeration holes see Specimen Local
Rule 8 in Part B of this Appendix.
4. Extreme Wetness, Mud, Poor Conditions and Protection of Course
a. Lifting an Embedded Ball, Cleaning
Where the ground is unusually soft, the Committee may, by
temporary Local Rule, allow the lifting of a ball which is embedded
in its own pitch-mark in the ground in an area "through the green"
which is not "closely mown" (Rule 25-2)
if it is satisfied that the proper playing of the game would
otherwise be prevented. The Local Rule shall be for that day only or
for a short period, and if practicable shall be confined to specified
areas. The Committee shall withdraw the Local Rule as soon as
conditions warrant and should not print it on the score card.
In similarly adverse conditions, the Committee may, by temporary
Local Rule, permit the cleaning of a ball "through the green".
b. "Preferred Lies" and "Winter Rules"
Adverse conditions, including the poor condition of the course or
the existence of mud, are sometimes so general, particularly during
winter months, that the Committee may decide to grant relief by
temporary Local Rule either to protect the course or to promote fair
and pleasant play. Such Local Rule shall be withdrawn as soon as
conditions warrant.
If this necessitates modification of a Rule of Golf the approval of the Governing Authority must be obtained.
Other matters which the Committee could cover by Local Rule
include:
6. Water Hazards
a. Lateral Water Hazards7. Defining Bounds and Margins
Specifying means used to define out of bounds, hazards, water hazards, lateral water hazards and ground under repair.
8. Dropping ZonesEstablishing special areas in which balls may or shall be dropped when it is not feasible or practicable to proceed exactly in conformity with Rule 24-2b (Immovable Obstruction), Rule 25-1b or Rule 25-1c (Ground Under Repair), Rule 26-1 (Water Hazards and Lateral Water Hazards) or Rule 28 (Ball Unplayable)
9. Priority on the CourseThe Committee may make regulations governing Priority on the Course (see Etiquette)
SPECIMEN LOCAL RULES
Within the policy set out in Part A of this Appendix, the Committee may adopt a Specimen Local Rule by referring, on a score card or notice board, to the examples given below. However, Specimen Local Rules 5, 6 or 7 should not be printed or referred to on a score card as they are all of limited duration.
1. Fixed Sprinkler Heads
All fixed sprinkler heads are immovable obstructions and relief
from interference by them may be obtained under Rule 24-2. In
addition, if such an obstruction on or within two club-lengths of the
putting green of the hole being played intervenes on the line of play
between the ball and the hole, the player may obtain relief, without
penalty, as follows:
If the ball lies off the putting green but not in a hazard and is
within two club-lengths of the intervening obstruction, it may be
lifted, cleaned and dropped at the nearest point to where the ball
lay which (a) is not nearer the hole, (b) avoids such intervention
and (c) is not in a hazard or on a putting green.
PENALTY FOR BREACH OF LOCAL RULE:
Match play - Loss of Hole;
Stroke play - Two strokes.
2. Stones in Bunkers
Stones in bunkers are movable obstructions (Rule 24-1 applies).
3. Protection of Young Trees
Protection of young trees identified by ____________________ . If
such a tree interferes with a player's stance or the area of his
intended swing, the ball must be lifted, without penalty, and dropped
in accordance with the procedure prescribed in Rule 24-2b(i)
(Immovable Obstruction). The ball may be cleaned when so lifted.
PENALTY FOR BREACH OF LOCAL RULE:

ball at the nearest spot not nearer the hole which avoids such
situation.
PENALTY FOR BREACH OF LOCAL RULE:
Match play - Loss of hole;
Stroke play - Two strokes.
CONDITIONS OF THE COMPETITION
Rule 33-1 provides, "The Committee shall lay down the conditions
under which a competition is to be played". Such conditions should
include many matters such as method of entry, eligibility, number of
rounds to be played, settling ties, etc. which it is not appropriate
to deal with in the Rules of Golf or this Appendix.
However, there are four matters which might be covered in the
Conditions of the Competition to which the Committee's attention is
specifically drawn by way of a Note to the appropriate Rule. These
are:
1. Specification of the Ball (Note to Rule 5-1)
Arising from the regulations for ball-testing under Rule 5-1, Lists of Conforming Golf Balls will be issued from time to time.
It is recommended that the Lists should be applied to all National and
County (or equivalent) Championships and to all top-class events when
restricted to low handicap players. In order to apply the Lists to a
particular competition the Committee must lay this down in the
Conditions of the Competition. This should be referred to in the
Entry Form, and also a notice should be displayed on the Club notice
board and at the 1st Tee along the following lines:
...........................(Name of Event)...............................
............................(Date and Club)................................
The ball the player uses shall be named on the current List of Conforming Golf Balls issued by the Royal and Ancient Golf Club of St. Andrews.
Note 1: A penalty statement will be required and must be either:
(a) "PENALTY FOR BREACH OF CONDITION:
Disqualification."
or
(b) "PENALTY FOR BREACH OF CONDITION:
Match play - Loss of each hole at which a breach occurred.
Stroke play - Two strokes for each hole at which a breach
occurred."
If option (b) is adopted this only applies to use of a ball which, whilst not on the List of Conforming Golf Balls, does conform to the specifications set forth in Rule 5 and Appendix III. The penalty for use of a ball which does not so conform is disqualification.
Note 2: In Club events it is recommended that no such condition be applied.
2. Time of Starting (Note to Rule 6-3a)
If the Committee wishes to act in accordance with the Note, the
following wording is recommended:
"If, in the absence of circumstances which warrant waiving the penalty of disqualification as provided in Rule 33-7, the player arrives at his starting point, ready to play, within
five minutes after his starting time, the penalty for failure to start on time is loss of the
first hole to be played in match play or two strokes in stroke play."
3. Practice
The Committee may make regulations governing practice in
accordance with the Note to Rule 7-1, Exception (c) to Rule 7-2, Note
2 to Rule 7 and Rule 33-2c.
4. Advice in Team Competitions
If the Committee wishes to act in accordance with the Note, the
following wording is recommended:
"In accordance with the Note to Rule 8-1 of the Rules of Golf each team may appoint one person (in addition to the persons from whom advice may be asked under that Rule) who may give advice to members of that team. Such person [if it is desired to insert any restriction on who may be nominated insert such restriction here] shall be identified to the Committee prior to the start of the Competition."
Any design in a club or ball which is not covered by Rules 4 and 5 and Appendices II and III, or which might significantly change the nature of the game, will be ruled on by the Royal and Ancient Golf Club of St Andrews and the United States Golf Association.
Note: Equipment approved for use or marketed prior to January 1st, 1988 which conforms to the Rules in effect in 1987 but does not conform to the 1988 and subsequent Rules may be used until December 31st, 1995; thereafter all equipment must conform to the current Rules.
Rule 4-1 prescribes general regulations for the design of clubs. The following paragraphs, which provide some specifications and clarify how Rule 4-1 is interpreted, should be read in conjunction with that Rule.
4-1a. GeneralAdjustability - Exception for Putters.
Clubs other than
putters shall not be designed to be adjustable except for weight.
Some other forms of adjustability are permitted in the design of a
putter, provided that:
(i) the adjustment cannot be readily made;
(ii) all adjustable parts are firmly fixed and there is no reasonable
likelihood of them working loose during a round; and
(iii) all configurations of adjustment conform with the Rules.
The disqualification penalty for purposely changing the playing
characteristics of a club during a
stipulated round
(Rule 4-2) applies to all clubs
including a putter.
Note: It is recommended that all putters with adjustable parts be submitted to the Royal and Ancient Golf Club of St. Andrews for a ruling.
4-1b. ShaftGenerally Straight. The shaft shall be at least 18 inches (457mm) in length. it shall be straight from the top of the grip to a point not more than 5 inches (127mm) above the sole, measured along the axis of the shaft and the neck or socket.
Bending and Twisting Properties. The shaft must be so designed and manufactured that at any point along its length:
(i) it bends in such a way that the deflection is the same regardless of how the shaft is rotated about its longitudinal axis; and
(ii) twist the same amount in both directions.
Attachment to Clubhead. The neck or socket must not be more than 5 inches (127mm) in length, measured from the top of the neck or socket to the sole along its axis. The shaft and the neck or socket must remain in line with the heel, or with a point to the right or left of the heel, when the club is viewed in the address position. The distance between the axis of the shaft or the neck or socket and the back of the heel must not exceed 0.625 inches (16mm).
Exception for Putters: The shaft or neck or socket of a putter may be fixed at any point in the head and need not remain in line with the heel. The axis of the shaft from the top to a point not more than 5 inches (127mm) above the sole must diverge from the vertical in the toe-heel plane by at least 10 degrees when the club is in its normal address position.
4-1c. Grip
(i) For clubs other than putters the grip must be generally circular
in cross-section, except that a continuous, straight,
slightly raised rib may be incorporated along the full
length of the grip.
(ii) A putter grip may have a non-circular cross-section,
provided the cross-section has no concavity, is symmetrical
and remains generally similar throughout the length of the
grip.
(iii) The grip may be tapered but must not have any bulge or
waist.
(iv) For clubs other than putters the axis of the grip must
coincide with the axis of the shaft.
(v) The cross-sectional dimension of a grip measured in any direction shall not exceed 1.75 inches (45mm).
(vi) A putter may have more than one grip, provided each is circular in cross-section and the axis of each coincides with the axis of the shaft.
Note: Putters approved for use or marketed prior to 1st January 1992 which are in breach of clause (vi), but otherwise conform, may be used until 31st December 1992.
4-1d. ClubheadDimensions. The dimensions of a clubhead (see diagram) are measured, with the clubhead in its normal address position, on horizontal lines between vertical projections of the outermost points of (i) the heel and the toe and (ii) the face and the back. If the outermost point of the heel is not clearly defined, it is deemed to be 0.625 inches (16mm) above the horizontal plane on which the club is resting in its normal address position.
Plain in Shape. The clubhead shall be generally plain in
shape. All parts shall be rigid, structural in nature and functional.
Features such as holes through the head, windows or transparencies, or appendages to the main body of the head such as plates, rods or fins for the purpose of meeting dimensional specifications, for aiming or for any purpose are not permitted. Exceptions may be made for putters.
Any furrows in or runners on the sole shall not extend into the face.
General. Except for specified markings, the surface roughness must not exceed that of decorative sandblasting. Markings must not have sharp edges or raised lips, as determined by a finger test. The material and construction of the face shall not be designed or manufactured to have the effect at impact of a spring, or to impart significantly more spin to the ball than a standard steel face, or to have any other effect which would unduly influence the movement of the ball.
"Impact Area" Markings. Markings within the area where impact is intended (the "impact area") are governed by the following:
(i) Grooves. A series of straight grooves with diverging sides and a symmetrical cross-section may be used (see diagram). The width and cross-section must be consistent across the face of the club and along the length of the grooves. Any rounding of groove edges shall be in the form of a radius which does not exceed 0.020 inches (0.5mm). The width of the grooves shall not exceed 0.035 inches (0.9mm), using the 30 degree method of measurement on file with the Royal and Ancient Golf Club of St. Andrews. The distance between edges of adjacent grooves must not be less than three times the width of a groove, and not less than 0.075 inches (1.9mm). The depth of a groove must not exceed 0.020 inches (0.5mm).
Note: Until 31st December 1995, a Committee is authorised to waive the above requirements for width and separation of grooves for clubs manufactured before 31st March 1990, provided the width of the grooves does not exceed 0.040 inches (1.00mm) and the distance between edges of adjacent grooves is not less than 2.3 times the width.
It is recommended that the granting of this waiver be the normal practice for amateur competition and, in that case, the Committee need not give written intimation that the waiver is being applied.
Where a Committee opts not to grant the waiver and to apply the Rule strictly (as it is entitled to do), this should be clearly stated in the Conditions of the Competition and the Entry Form.
From 1st January 1996, the Rule may no longer be waived and markings on clubs must meet all the specifications of the Rule.
(ii) Punch Marks. Punch marks may be used. The area of any such mark must not exceed 0.0044 square inches (2.8 sq.mm). A mark must not be closer to an adjacent mark than 0.168 inches (4.3mm) measured from centre to centre. The depth of a punch mark must not exceed 0.040 inches (1.0mm). If punch marks are used in combination with grooves, a punch mark must not be closer to a groove than 0.168 inches (4.3mm), measured from centre to centre.
Decorative Markings. The centre of the impact area may be indicated by a design within the boundary of a square whose sides are 0.375 inches (9.5mm) in length. Such a design must not unduly influence the movement of the ball. Decorative markings are permitted outside the impact area.
Non-metallic Club Face Markings. The above specifications for markings do not apply to clubs on which the impact area of the face is non-metallic and whose loft angle is 24 degrees or less, but markings which could unduly influence the movement of the ball are prohibited. Clubs with this type of face and a loft angle exceeding 24 degrees may have grooves of maximum width 0.040 inches (1.00mm) and maximum depth 1½ times the groove width, but must otherwise conform to the markings specifications above.
Putter Face Markings. The specifications above with regard to club face markings do not apply to putters.
THE BALL
a. Weight
The weight of the ball shall not be greater than 1.620 ounces
avoirdupois (45.93gm).
b. Size
The diameter of the ball shall be not less than 1.680 inches
(42.67mm). This specification will be satisfied if, under its own
weight, a ball falls through a 1.680 inches diameter ring gauge in
fewer than 25 out of 100 randomly selected positions, the test being
carried out at a temperature of 23 ±1°C.
c. Spherical Symmetry
The ball must not be designed, manufactured or intentionally modified to have flight properties which differ from those of a spherically symmetrical ball.
Furthermore the ball will not conform to the Rules of Golf if it fails to satisfy the performance specifications outlined below:
As described in procedures on file at the Royal and Ancient Golf Club of St Andrews, each ball type will be tested using 40 balls of that type, in 20 pairs. One ball of each pair will be launched spinning about one specified axis; the other ball of each pair will be launched spinning about a different, but also specified axis.
Differences in carry and time of flight between the two balls of each pair will be recorded. If the mean of the differences in carry is greater than 3.0 yards, and that value is significant at the 5% level, OR if the mean of the differences in time of flight is greater than 0.20 seconds, and that value is significant at the 5% level, the ball type will not conform to the Rules of Golf.
Note: Methods of determining whether a ball performs as if it were generally spherically symmetrical may be subject to change as instrumentation becomes available to measure other properties accurately, such as the aerodynamic coefficient of lift, coefficient of drag and moments of inertia.
d. Initial Velocity
The velocity of the ball shall not be greater than 250 feet
(76.2m) per second when measured on apparatus approved by the Royal
and Ancient Golf Club of St. Andrews and the United States Golf Association. A maximum tolerance of 2% will
be allowed. The temperature of the ball when tested shall be 23 ±1°C.
Appendix I: Part A
LOCAL RULES
Rule 33-8 provides, "The Committee
may make and publish Local Rules for abnormal conditions if they are
consistent with the policy of the Governing Authority for the country
concerned as set forth in Appendix I to these Rules. A penalty
imposed by a Rule of Golf shall not be waived by a Local Rule."
Such abnormal conditions may include those listed below. Otherwise,
detailed information regarding acceptable and prohibited Local Rules
is provided in "Decisions on the Rules of Golf" under Rule 33-8.
If local conditions interfere with the proper playing of the game and
it is considered necessary to modify a Rule of Golf, the approval of
the Governing Authority must be obtained.
1. Obstructions
a. General
Clarifying the status of objects which may be obstructions
(Rule 24).
Declaring any construction to be an integral part of the course and,
accordingly, not an obstruction, e.g. built-up sides of teeing
grounds, putting greens and bunkers Rule 24
and Rule 33-2a).
b. Stones in Bunkers
Allowing the removal of stones in bunkers by declaring them to be
"movable obstructions" (Rule 24).
c. Roads and Paths
(i) Declaring artificial surfaces and sides of roads and paths to
be integral parts of the course, or
(ii) Providing relief of the type afforded under
Rule 24-2b from roads and paths not
having artificial surfaces and sides if they could unfairly affect
play.
d. Fixed Sprinkler Heads
Providing relief from intervention by fixed sprinkler heads within
two club-lengths of the putting green when the ball lies within two
club-lengths of the sprinkler head.
e. Protection of Young Trees
Providing relief for the protection of young trees.
f. Temporary Obstructions
Specimen Local Rules for temporary obstructions (e.g. grandstands,
television cables and equipment, etc). for application in Tournament
Play are available from the Royal and Ancient Golf Club of St.
Andrews.
2. Areas of the Course Requiring Preservation
Assisting preservation of the course by defining areas, including turf nurseries, young plantations and other parts of the course under cultivation, as "ground under repair" from which play is prohibited.
3. Unusual Damage to the Course or Accumulation of Leaves (or the like)
Declaring such areas to be "ground under repair" (Rule 25). The Committee may, by Local Rule, deny relief from interference with a player's stance by such areas - see Note to Rule 25-1a.
Note: For relief from aeration holes see Specimen Local Rule 8 in Part B of this Appendix.
4. Extreme Wetness, Mud, Poor Conditions and Protection of Course
a. Lifting an Embedded Ball, Cleaning
Where the ground is unusually soft, the Committee may, by
temporary Local Rule, allow the lifting of a ball which is embedded
in its own pitch-mark in the ground in an area "through the green"
which is not "closely mown" (Rule 25-2)
if it is satisfied that the proper playing of the game would
otherwise be prevented. The Local Rule shall be for that day only or
for a short period, and if practicable shall be confined to specified
areas. The Committee shall withdraw the Local Rule as soon as
conditions warrant and should not print it on the score card.
In similarly adverse conditions, the Committee may, by temporary
Local Rule, permit the cleaning of a ball "through the green".
b. "Preferred Lies" and "Winter Rules"
Adverse conditions, including the poor condition of the course or
the existence of mud, are sometimes so general, particularly during
winter months, that the Committee may decide to grant relief by
temporary Local Rule either to protect the course or to promote fair
and pleasant play. Such Local Rule shall be withdrawn as soon as
conditions warrant.
When the Committee is required to prohibit play from
environmentally-sensitive areas which are on or adjoin the course, it
should make a Local Rule clarifying the relief procedure.
An environmentally-sensitive area is an area so declared by an
appropriate authority, entry into and/or play from which is
prohibited for environmental reasons. Such an area may be defined as
ground under repair, a water hazard, a lateral water hazard or out of
bounds at the discretion of the Committee provided that, in the case
of an environmentally-sensitive area which has been defined as a
water hazard or a lateral water hazard, the area is, by Definition, a
water hazard.
Note: The Committee may not declare an area to be environmentally-sensitive.
A specimen Local Rule is detailed in "Decisions on the Rules of Golf".
Other matters which the Committee could cover by Local Rule include:
6. Water Hazards
a. Lateral Water Hazards
Clarifying the status of sections of water hazards which may be
lateral water hazards (Rule 26)
b. Provisional Ball
Permitting play of a provisional ball for a ball which may be in a
water hazard of such character that it would be impracticable to
determine whether the ball is in the hazard or to do so would unduly
delay play. In such a case, if a provisional ball is played and the
original ball is in a water hazard, the player may play the original
ball as it lies or continue the provisional ball in play, but he may
not proceed under Rule 26-1.
Specifying means used to define out of bounds, hazards, water hazards, lateral water hazards and ground under repair.
8. Dropping ZonesEstablishing special areas in which balls may or shall be dropped when it is not feasible or practicable to proceed exactly in conformity with Rule 24-2b (Immovable Obstruction), Rule 25-1b or Rule 25-1c (Ground Under Repair), Rule 25-3 (Wrong Putting Green), Rule 26-1 (Water Hazards and Lateral Water Hazards) or Rule 28 (Ball Unplayable)
9. Priority on the CourseThe Committee may make regulations governing Priority on the Course (see Etiquette)
SPECIMEN LOCAL RULES
Within the policy set out in Part A of this Appendix, the Committee may adopt a Specimen Local Rule by referring, on a score card or notice board, to the examples given below. However, Specimen Local Rules 5, 6 or 7 should not be printed or referred to on a score card as they are all of limited duration.
1. Fixed Sprinkler Heads
All fixed sprinkler heads are immovable obstructions and relief
from interference by them may be obtained under Rule 24-2. In
addition, if such an obstruction on or within two club-lengths of the
putting green of the hole being played intervenes on the line of play
between the ball and the hole, the player may obtain relief, without
penalty, as follows:
If the ball lies off the putting green but not in a hazard and is
within two club-lengths of the intervening obstruction, it may be
lifted, cleaned and dropped at the nearest point to where the ball
lay which (a) is not nearer the hole, (b) avoids such intervention
and (c) is not in a hazard or on a putting green.
PENALTY FOR BREACH OF LOCAL RULE:
Match play - Loss of Hole;
Stroke play - Two strokes.
2. Stones in Bunkers
Stones in bunkers are movable obstructions (Rule 24-1 applies).
3. Protection of Young Trees
Protection of young trees identified by ____________________ . If
such a tree interferes with a player's stance or the area of his
intended swing, the ball must be lifted, without penalty, and dropped
in accordance with the procedure prescribed in Rule 24-2b(i)
(Immovable Obstruction). The ball may be cleaned when so lifted.
PENALTY FOR BREACH OF LOCAL RULE:
Match play - Loss of hole;
Stroke play - Two strokes.
4. Ground Under Repair: Play Prohibited
If a player's ball lies in an area of "ground under repair" from
which play is prohibited, or if such an area of "ground under repair"
interferes with the player's stance or the area of his intended swing
the player must take relief under Rule 25-1.
PENALTY FOR BREACH OF LOCAL RULE:
Match play - Loss of hole;
Stroke play - Two strokes.
5. Lifting an Embedded Ball
(Specify the area if practicable) . . . through the green, a ball
embedded in its own pitch-mark in ground other than sand may be
lifted, cleaned and dropped, without penalty, as near as possible to
the spot where it lay but not nearer the hole.
PENALTY FOR BREACH OF LOCAL RULE:
Match play - Loss of hole;
Stroke play - Two strokes.
6. Cleaning Ball
(Specify the area if practicable) ... through the green a ball may
be lifted, cleaned and replaced without penalty.
Note: The position of the ball shall be marked before it is lifted under this Local Rule - see Rule 20-1.
7. "Preferred Lies" and "Winter Rules"
A ball lying on any "closely mown area" through the green may,
without penalty, be moved or may be lifted, cleaned and placed within
six inches of where it originally lay, but not nearer the hole. After
the ball has been so moved or placed, it is in play.
PENALTY FOR BREACH OF LOCAL RULE:
Match play - Loss of hole;
Stroke play - Two strokes.
8. Aeration Holes
If a ball comes to rest in an aeration hole, the player may,
without penalty, lift the ball and clean it. Through the green, the
player shall drop the ball as near as possible to where it lay, but
not nearer the hole. On the putting green, the player shall place the
ball at the nearest spot not nearer the hole which avoids such
situation.
PENALTY FOR BREACH OF LOCAL RULE:
Match play - Loss of hole;
Stroke play - Two strokes.
CONDITIONS OF THE COMPETITION
Rule 33-1 provides, "The Committee shall lay down the conditions
under which a competition is to be played". Such conditions should
include many matters such as method of entry, eligibility, number of
rounds to be played, settling ties, etc. which it is not appropriate
to deal with in the Rules of Golf or this Appendix. Detailed
information regarding such conditions is provided in "Decisions on
the Rules of Golf" under Rule 33-1.
However, there are seven matters which might be covered in the
Conditions of the Competition to which the Committee's attention is
specifically drawn by way of a Note to the appropriate Rule. These
are:
1. Specification of the Ball (Note to Rule 5-1)
a. List of Conforming Golf Balls
Arising from the regulations for ball-testing under Rule 5-1, a
List of Conforming Golf Balls will be issued from time to time.
It is recommended that the List should be applied to all National and
County (or equivalent) Championships and to all top-class events when
restricted to low handicap players. In order to apply the List to a
particular competition the Committee must lay this down in the
Conditions of the Competition. This should be referred to in the
Entry Form, and also a notice should be displayed on the Club notice
board and at the 1st Tee along the following lines:
...........................(Name of Event)...............................
............................(Date and Club)................................
"The Ball (Note to Rule 5-1).
The ball the player uses shall be named on the current List of Conforming Golf Balls issued by the Royal and Ancient Golf Club of St. Andrews."
A penalty statement will be required and must be either:
(a) "PENALTY FOR BREACH OF CONDITION:
Disqualification."
or
(b) "PENALTY FOR BREACH OF CONDITION:
Match play - Loss of each hole at which a breach occurred.
Stroke play - Two strokes for each hole at which a breach
occurred."
If option (b) is adopted this only applies to use of a ball which, whilst not on the List of Conforming Golf Balls, does conform to the specifications set forth in Rule 5 and Appendix III. The penalty for use of a ball which does not so conform is disqualification.
b. One Ball Condition
If it is desired to prohibit changing brands and types of golf
balls during a stipulated round, the following condition is
recommended:
"Limitation on Balls Used During Round: (Note to Rule 5-1).
(i) "One Ball" Condition
During a stipulated round, the ball the player uses must be of the
same brand and type as detailed by a single entry on the current List
of Conforming Golf Balls.
PENALTY FOR BREACH OF CONDITION:
Match Play - At the conclusion of the hole at which the breach is
discovered, the state of the match shall be adjusted by deducting one
hole for each hole at which a breach occurred; maximum deduction per
round: Two holes.
Stroke Play - Two strokes for each hole at which any breach occurred;
maximum penalty per round; Four strokes.
(ii) Procedure When Breach Discovered
When a player discovers that he has used a ball in breach of this
condition, he shall abandon that ball before playing from the next
teeing ground and complete the round using a proper ball; otherwise,
the player shall be disqualified. If discovery is made during play of
a hole and the player elects to substitute a proper ball before
completing that hole, the player shall place a proper ball on the
spot where the ball used in breach of the condition lay."
Note: In Club events it is recommended that no such condition be applied.
2. Time of Starting (Note to Rule 6-3a)If the Committee wishes to act in accordance with the Note, the
following wording is recommended:
"If the player arrives at his starting point, ready to play, within
five minutes after his starting time, in the absence of circumstances
which warrant waiving the penalty of disqualification as provided in
Rule 33-7, the penalty for failure to start on time is loss of the
first hole to be played in match play or two strokes in stroke play.
Penalty for lateness beyond five minutes is disqualification."
The Committee may lay down pace of play guidelines, to help prevent slow play, in accordance with Note 2 to Rule 6-7.
4. Suspension of Play Due to a Dangerous Situation (Note to Rule 6-8b)If the Committee wishes to act in accordance with the Note, the
following wording is recommended:
"When play is suspended by the Committee for a dangerous situation
(e.g. lightning, tornadoes, etc.) if the players in a match or group
are between the play of two holes, they shall not resume play until
the Committee has ordered a resumption of play. If they are in the
process of playing a hole, they shall discontinue play immediately
and shall not thereafter resume play until the Committee has ordered
a resumption of play.
The signal for suspending play due to a dangerous situation will be
........................................
PENALTY FOR BREACH OF CONDITION:
Disqualification "
The Committee may make regulations governing practice in accordance with the Note to Rule 7-1, Exception (c) to Rule 7-2, Note 2 to Rule 7 and Rule 33-2c.
6. Advice in Team CompetitionsIf the Committee wishes to act in accordance with the Note, the following wording is recommended:
"In accordance with the Note to Rule 8 of the Rules of Golf each team may appoint one person (in addition to the persons from whom advice may be asked under that Rule) who may give advice to members of that team. Such person (if it is desired to insert any restriction on who may be nominated insert such restriction here) shall be identified to the Committee before giving advice."
7. New HolesThe Committee may provide, in accordance with the Note to Rule 33-2b, that the holes and teeing grounds for a single round competition, being held on more than one day, may be differently situated on each day.
DESIGN OF CLUBS
Any design in a club or ball which is not covered by Rules 4 and 5 and Appendices II and III, or which might significantly change the nature of the game, will be ruled on by the Royal and Ancient Golf Club of St. Andrews and the United States Golf Association.
Clubs must not be substantially different from the traditional and customary form and make.
Rule 4-1 prescribes general
regulations for their design. The following paragraphs, which provide
some specifications and clarify how Rule 4-1 is interpreted, should
be read in conjunction with that Rule.
Where a club, or part of a club, is required to have some specific
property, this means that it must be designed and manufactured with
the intention of having that property. The finished club or part must
have that property within manufacturing tolerances appropriate to the
material used.
Adjustability - Exception for Putters.
Clubs other than
putters shall not be designed to be adjustable except for weight.
Some other forms of adjustability are permitted in the design of a
putter, provided that:
(i) the adjustment cannot be readily made;
(ii) all adjustable parts are firmly fixed and there is no reasonable
likelihood of them working loose during a round; and
(iii) all configurations of adjustment conform with the Rules.
The disqualification penalty for purposely changing the playing
characteristics of a club during a
stipulated round
(Rule 4-2) applies to all clubs
including a putter.
Note: It is recommended that all putters with adjustable parts be submitted to the Royal and Ancient Golf Club of St. Andrews for a ruling.

(i) For clubs other than putters the grip must be circular in cross-section, except that a continuous, straight, slightly raised rib may be incorporated along the full length of the grip, and a slightly indented spiral is permitted on a wrapped grip or a replica of one. (ii) A putter grip may have a non-circular cross-section, provided the cross-section has no concavity, is symmetrical and remains generally similar throughout the length of the grip. (iii) The grip may be tapered but must not have any bulge or waist. Its cross-sectional dimension measured in any direction must not exceed 1.75 inches (45mm). (iv) For clubs other than putters the axis of the grip must coincide with the axis of the shaft. (v) A putter may have more than one grip, provided each is circular in cross-section and the axis of each coincides with the axis of the shaft. |

Dimensions. The dimensions of a clubhead are measured, with the clubhead in its normal address position, on horizontal lines between vertical projections of the outermost points of (i) the heel and the toe and (ii) the face and the back (See Figure VII, dimension A). If the outermost point of the heel is not clearly defined, it is deemed to be 0.625 inches (16mm) above the horizontal plane on which the club is resting in its normal address position (See Figure VII, dimension B). |

|---|---|---|
Plain in Shape.
The clubhead shall be generally plain in
shape. All parts shall be rigid, structural in nature and
functional.
It is not practicable to define plain in shape precisely and
comprehensively but features which are deemed to be in breach of this
requirement and are therefore not permitted include:
(a) holes through the head,
(b) transparent material added for other than decorative or
structural purposes,
(c) appendages to the main body of the head such as knobs, plates,
rods or fins,
for the purpose of meeting dimensional specifications, for aiming or
for any other purpose. Exceptions may be made for putters.
Any furrows in or runners on the sole shall not extend into the face.
General.
The material and construction of the face shall
not have the effect at impact of a spring, or impart significantly
more spin to the ball than a standard steel face, or have any other
effect which would unduly influence the movement of the ball.
![]() Figure VIII |
Impact Area Roughness and Material. Except for markings specified in the following paragraphs, the surface roughness within the area where impact is intended (the "impact area") must not exceed that of decorative sandblasting, or of fine milling. The impact area must be of a single material. Exceptions may be made for wooden clubs (see Figure VIII). |
|---|
"Impact Area" Markings.
Markings in the impact area must
not have sharp edges or raised lips as determined by a finger rest.
Grooves or punch marks in the impact area must meet the following
specifications:
(i) Grooves.
A series of straight grooves with diverging
sides and a symmetrical cross-section may be used (see Figure IX).
The width and cross-section must be consistent across the face of the
club and along the length of the grooves. Any rounding of groove
edges shall be in the form of a radius which does not exceed 0.020
inches (0.5mm). The width of the grooves shall not exceed 0.035
inches (0.9mm), using the 30 degree method of measurement on file
with the Royal and Ancient Golf Club of St. Andrews. The distance
between edges of adjacent grooves must not be less than three times
the width of a groove, and not less than 0.075 inches (1.9mm). The
depth of a groove must not exceed 0.020 inches (0.5mm).

(ii) Punch Marks.
Punch marks may be used. The area of any
such mark must not exceed 0.0044 square inches (2.8 sq.mm). A mark
must not be closer to an adjacent mark than 0.168 inches (4.3mm)
measured from centre to centre. The depth of a punch mark must not
exceed 0.040 inches (1.0mm). If punch marks are used in combination
with grooves, a punch mark must not be closer to a groove than 0.168
inches (4.3mm), measured from centre to centre.
Decorative Markings.
The centre of the impact area may be
indicated by a design within the boundary of a square whose sides are
0.375 inches (9.5mm) in length. Such a design must not unduly
influence the movement of the ball. Decorative markings are permitted
outside the impact area.
Non-metallic Club Face Markings.
The above specifications
apply to clubs on which the impact area of the face is of metal or a
material of similar hardness. They do not apply to clubs with faces
made of other materials and whose loft angle is 24 degrees or less,
but markings which could unduly influence the movement of the ball
are prohibited. Clubs with this type of face and a loft angle
exceeding 24 degrees may have grooves of maximum width 0.040 inches
(1.00mm) and maximum depth 1½ times the groove width, but must
otherwise conform to the markings specifications above.
Putter Face Markings.
The specifications above with regard
to club face markings and surface roughness do not apply to putters.
THE BALL
Any design in a club or ball which is not covered by Rules 4 and 5 and Appendices II and III, or which might significantly change the nature of the game, will be ruled on by the Royal and Ancient Golf Club of St. Andrews and the United States Golf Association.
a. Weight
The weight of the ball shall not be greater than 1.620 ounces
avoirdupois (45.93gm).
b. Size
The diameter of the ball shall be not less than 1.680 inches
(42.67mm). This specification will be satisfied if, under its own
weight, a ball falls through a 1.680 inches diameter ring gauge in
fewer than 25 out of 100 randomly selected positions, the test being
carried out at a temperature of 23 ±1°C.
c. Spherical Symmetry
The ball must not be designed, manufactured or intentionally
modified to have properties which differ from those of a spherically
symmetrical ball.
d. Initial Velocity
The velocity of the ball shall not be greater than 250 feet
(76.2m) per second when measured on apparatus approved by the Royal
and Ancient Golf Club of St. Andrews. A maximum tolerance of 2% will
be allowed. The temperature of the ball when tested shall be 23
±1°C.
e. Overall Distance Standard
A brand of golf ball, when tested on apparatus approved by the
Royal and Ancient Golf Club of St. Andrews under the conditions set
forth in the Overall Distance Standard for golf balls on file with
the Royal and Ancient Golf Club of St. Andrews, shall not cover an
average distance in carry and roll exceeding 280 yards (256 metres)
plus a tolerance of 6%.
Note: The 6% tolerance will be reduced to a minimum of 4% as test techniques are improved.
