Fewer crosscut seams to stretch and need restitching in a few years. The outer sailcloth is heavier and can be UV treated, so it's made for the stronger winds and sun when reefed. Made from two weights of Dacron, tested and matched to offer a perfect shape. Includes foam luff pad, telltales, leechcord, area reduction marks, and sail bag. The most durable sail on the market today.
Durability means more strength, more strength offers superior speed.
Durability Triangles are the weakness in conventional sails, since they cut across the strong yarns in the fabric. Instead, the Kappa Cut uses parallelograms which maintain the fabric's integrity. Sails made from parallelograms last twice as long as their triangular gored counterparts. Overlapping parallelograms increase the strength factor. More overlaps in higher load areas eliminate heavy corner reinforcements.
