Hey Don,

Stupid question: What precisely is S-curve? Is it when the leach makes an 's' with the very edge, as seen from behind the sail, or do your battens actually bend off near the leach in an 's' shape, as viewed from the top down?



Maybe I need to look more carefully, but I've not noticed either condition. (Except for the squaretop opening up the top leach under heavy heavy DH; but that's a design goal, right?)
