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
A sail from one rig shall not be used with another sized rig.
H.2 Construction
Construction shall be a soft sail of a single ply.
The Jib and Mainsail of any given rig size shall be constructed
from the same ply.
All sails shall be constructed of a single panel with no seams
and the maker shall not try to introduce camber (shape) into the
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
positioned within 5mm of points H, I, J & K . The top batten shall
have a maximum length of 100mm and the lower three battens a maximum
length of 50mm. Maximum width 12mm.
C Mainsail - Shall have three battens with their outer ends positioned
within 5mm of points I, J & K. Maximum length of 50mm. Maximum width 12mm.
Jibs - May have two battens of maximum length 50mm and maximum width 12mm
with their outer ends positioned anywhere along the Jib leech (back edge).
H.4 Reinforcement Patches.
Reinforcement patches may be used at the sail corners, batten ends and
mainsail luff attachment points. These shall be of self-adhesive material
of not more than four layers.
Sail corner reinforcement must fit within an 80mm radius of the sail corner point.
Mainsail luff attachment point patches and batten end patches, at either
end of the batten, shall fit within a circle of 20mm diameter
Mainsail luff tabling is not permitted.
H.5 Jib Luff
The Jib Luff shall form a straight line between points A & C.
Tabling at the luff (front edge) shall form a pocket for the Forestay. Maximum
width of tabling shall be 12mm. Tabling forms part of the sail area and must
fit within the sail dimensions. Tabling shall be one, continuous pocket finishing
within 10mm of points A & C.
H.6 Leech Profile
Jib - The Jib leech shall form a straight line between points D & E.
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.
Mainsail - The Mainsail foot shall form a fair curve between points A & L with the
point of maximum curvature M as described in Diagram 2.
