Bob,
Thanks for the mention. It's good to hear from someone that remembers our windsurfer sails. That was a great period for me. Designing, and testing sailboard sails, resulted in some real performance breakthroughs. Alot of this has been applied to multihull sail designs. BTW, Tem Berkstresser just arrived at the loft yesterday. He is picking up a new Vectran screacher, and fullbatten jib for his 60' cat that he designed, and built.(with a little design help from Bill Roberts) It seems that most of the top US windsurfer sailors, and industry people are going to multihulls. Tem's ex partner Pat LeMahaute, is about to finish his 38' Kurt Hughes Tri,and Keith Notery's 60' cat is about done, as well. Many others are racing Corsairs, and beach cats.
