CLARIFICATION OF HOLLOW LEECH REQUIREMENT IN CR 6.5.5 (2011-06-07)
Q1: Does a jib that has a leech shape that has segments that are straight or convex meet the requirements of CR 6.5.5?
6.5.5. The jib shall have a hollow leech and while racing, shall be attached to and operated on the standard roller furling system using #6 luff tape. UV protective tape may be applied to the leech and foot to cover the sail when roller furled.
A1: No. The term hollow refers to a concave shape. The interpretation of 'hollow leech' is that the leech should have a smooth arc such that when a straight line is drawn between any two batten pockets or an end point and any batten pocket, the leech edge will be concave relative to that line. See the Equipment Rules of Sailing, Section B.4.2, for the measurement method.
