A3.01. MAINSAILS
Refers to Class Rule 05.02.08. Replace 05.02.00 by:
A3.01.01 Sail Area of the Mainsail (SMGV) is given by:
SMGV = P*0,25*(0,5*E1+E2+E3+E4+0,5*E5)
A3.01.02 Hoist (P)
P shall be measured between the inner edges of two "one-inch" Limit Marks positioned on the Mast. The lower edge of the upper mark corresponds to the top of the Mainsail headboard.
The upper edge of the lower mark corresponds to a fair extension of the top of the boom in case of Mainsails fully secured at the Foot, or to a fair extension of the straight line joining the Clew Point to the Tack Point in case of loose footed Mainsails.
A3.01.03 Widths
E1 shall be the Maximum fore and aft dimension of the top of the Mainsail.
E2, E3 and E4 shall be the Three-Quarter Width, Half Width and Quarter Width (see figure 3a).
E5 shall be the Foot Length of the Mainsail.
All measurement points shall be at the extreme outside of rope or fabric of the Sail's edge, with the Sail laid flat.
A3.01.04 The points on the Leech from which the cross measurements are taken shall be determined bridging any hollows in the Leech with straight lines joining the aft extremities of the battens or the points at which they emerge from the fabric of the Sail.
A3.01.05 The Foot roach shall not be greater than 0,15 metre. It shall be measured from the straight line joining the Clew Point to the Tack Point.
A3.01.06 Battens
The number of battens in the Mainsail shall be limited to three. The batten length shall not be greater than 0,25* the boom Outer Point Distance (see ERS F.12.1).
A3.02. SPINNAKERS
