DF對於帆的建造制訂得很嚴格,連帆骨的位置與尺寸都有明確規定,
不過就是因為制訂得很明確,比較有規則可依循及競賽的公平性.
Section H - Sails
H.1 Usage

sail by means of heat or force.
The sails shall be attached to the rigging and spars by means of
a single hole positioned within 10mm of each sail corner point
(points A, C & E Jib, A, G & L Mainsail) and three other suitable
positions along the mainsail luff. Metal eyelets may be used to
reinforce these holes.
H.3 Battens
A & B Mainsails - Shall have four battens with their outer ends

fit within the sail dimensions. Tabling shall be one, continuous pocket finishing
within 10mm of points A & C.
H.6 Leech Profile

Mainsail - The Mainsail leech shall be formed by a series of straight lines beween
the leech points G, H, I, J, K & L.
H.7 Foot Profile
Jib - The Jib foot shall form a straight line between points A & E.
