SAIL MEASUREMENT RULES Sails shall be measured in accordance to ISAF ERS (Equipment Rules of Sailing) Section G. (See information included later below) Sail material shall be any Dacron/Polyester woven or composite with Mylar material supplied to sail makers in commercially available roll form to all. (No molded or string sails): Mainsail Size Rules 1. Max Luff (Tack Point to Head Point): 6400mm 2. Max Leech (Head Point to Clew Point): 6750mm 3. Max Foot (Tack Point to Clew Pint): 2260mm 4. Max Top Head width: 160mm 5. Main ¼ Leech Girth: 2200mm 6. Main ½ Leech Girth: 1890mm 7. Main ¾ Leech Girth: 1180mm 8. Top Batten Pocket max length: 900mm 9. Top batten from Head Point shall intersect leech: 1000mm minimum 10. Maximum number of battens 7 battens max. Jib Size Rules 1. Max Luff (Tack Point to Head Point): 4725mm 2. Max Leech (Head Point to Clew Point): 4600mm 3. Max Foot (Tack Point to Clew Point): 1500mm 4. Max Head Width 60mm 5. Max number of leech battens 3 battens 6. Max Batten lengths each 300mm 7.

5 Notes on how to establish measurement points and then to measure sails: Mainsail Measurement Points: 1. Lay sail on flat surface. 2. Remove battens from Mainsail. 3. Fold Mainsail down leech taking Head Point (intersection of top of sail with boltrope) to Clew Point (projected intersection of leech line with foot line). 4. Make mark at the fold on the Leech. This is Mainsail ½ Leech Point. 5. Open sail up again and now take Head Point to Mainsail ½ Leech Point. Make a mark on the fold in the Leech. This is the Mainsail ¾ Leech Point. 6. Fold the Mainsail Clew Point to the Mainsail ½ Leech Point. Make a mark at the fold. This is the Mainsail ¼ Leech Point. Mainsail Measurement (a guide on Halcat Mainsail measurement): 1. Lay Mainsail out on flat surface. 2. Use a steel tape of suitable length (8m). 3. Hold the sail slightly taut, not stretched. 4. Measure Luff, Leech and Foot in straight lines from sail corners being Head Point, Tack Point and Clew Point. (Projected as necessary, see drawing below.) 5. Then measure all girth sizes at the ¼, ½, and ¾ Leech Point marks, by holding the zero of the tape on the leech mark and taking the tape to the outside of the Luff Bolt, arcing the tape up and down the sail until the SHORTEST measurement is found. (This will actually be perpendicular to the luff). This measurement must be checked against the corresponding rule and must not exceed the rule measurement. 6. Top width is measured from outside of Bolt Rope at sail top, along the top of the sail at 90 degrees to luff past the head board to the Aft Head Point where the Leech starts. 7. Top Batten position is measured by holding zero of tape at Head Point and measuring in a straight line to where the top batten intersects the Leech. This measurement must be not less than 1000mm. Jib Measurement (a guide on Halcat Jib Measurement): 1. Lay sail on flat surface. 2. Hold the sail slightly taut, not stretched. 3. Measure Luff, Leech and Foot in straight lines from sails corners being Head Point, Tack Point and Clew Point. (Projected as necessary, see drawing below.) The jib luff wire is NOT part of the sail, so only measure the sail material. Measurements must not exceed the rules.
6 4. Measure top width of jib from Head Point to Aft Head Point. This must not exceed 60mm. 5. Hold the Measuring Tape along the length of the jib Leech between Aft Head Point and Clew Point. The Leech must be straight or hollow. (No Roach) 6. Measure battens lengths in the sail by feeling where they start and end. Battens must not exceed 300mm in length. ISAF EQUIPMENT RULES OF SAILING (ERS) G.7 PRIMARY SAIL DIMENSIONS (See drawings above) See Drawings above from ISAF ERS. G.7.1 Foot Length The distance between the clew point and the tack point.

G.7.5 Half Width (See drawing above) (a) MAINSAIL and HEADSAIL: The shortest distance between the half leech point and the luff.

G.7.8 Top Width (See drawing above). (a) Top Width MAINSAIL and HEADSAIL: The distance between the head point and the aft head point.
8 G.4 SAIL CORNER MEASUREMENT POINTS G.4.1 Clew Point (See drawings below) The intersection of the foot and the leech, each extended as necessary. G.4.2 Head Point (See drawing below) (a) MAINSAIL: The intersection of the luff, extended as necessary, and the line through the highest point of the sail at 90 to the luff. (b) HEADSAIL: The intersection of the luff, extended as necessary, and the line through the highest point of the sail, excluding attachments, at 90 to the luff. G.4.3 Tack Point (See drawing below) The intersection of the foot and the luff, each extended as necessary.
