G1.3 Positioning

Class insignia, national letters and sail numbers shall be positioned as follows:

(a) Except as provided in rules G1.3(d) and G1.3(e), class insignia, national letters and sail numbers shall when possible be wholly above an arc whose centre is the head point and whose radius is 60% of the leech length. They shall be placed at different heights on the two sides of the sail, those on the starboard side being uppermost.

(b) The class insignia shall be placed above the national letters. If the class insignia is of such a design that two of them coincide when placed back to back on both sides of the sail, they may be so placed.

(c) National letters shall be placed above the sail number.

(d) The national letters and sail number shall be displayed on the front side of a spinnaker but may be placed on both sides. They shall be displayed wholly below an arc whose centre is the head point and whose radius is 40% of the foot median and, when possible, wholly above an arc whose radius is 60% of the foot median.

(e) The national letters and sail number shall be displayed on both sides of a headsail whose clew can extend behind the mast 30% or more of the mainsail foot length. They shall be displayed wholly below an arc whose centre is the head point and whose radius is half the luff length and, if possible, wholly above an arc whose radius is 75% of the luff length.

G2 OTHER BOATS

Other boats shall comply with the rules of their national authority or class association in regard to the allotment, carrying and size of insignia, letters and numbers. Such rules shall, when practicable, conform to the above requirements.

G3 CHARTERED OR LOANED BOATS

When so stated in the notice of race or sailing instructions, a boat chartered or loaned for an event may carry national letters or a sail number in contravention of her class rules.

G4 WARNINGS AND PENALTIES

When a protest committee finds that a boat has broken a rule of this appendix it shall either warn her and give her time to comply or penalize her.

G5 CHANGES BY CLASS RULES

ISAF classes may change the rules of this appendix provided the changes have first been approved by the ISAF.
