Several thought or, question provoking perspectives.....

Are any of the new-technology boat designs (F18's,etc.) using pinheads or square tops from the get go?

Considering the Tornado, Tiger, F18's, about how often have their respective sail plan designs evolved after considering real-world experiences? And, have they evolved towards pin-heads or square-tops?

Leaves me wondering though, in getting back to one of the original questions; does anyone know of a sailmaker who has perfected a square-top sail design for a Nacra 5.5? Or, is it pretty much a chance deal?
