This is a Wing Sail Catamaran project that I started over 4 years ago after seeing the new AC 45s introduced to the America's Cup races. The model uses PVC sheet, Carbon Fiber tubing and 377 Dupont Mylar to "skin" the wings. The "Cookie Cutter" construction technique allows me to make quick inexspensive changes to the design without having to scrap a model and start over, everything is tweekable. Two Catamaran models are shown here, but I have created a total of four boats during design development, one of which only sailed once,and poorly. But that one sailing taught me alot, and I started another boat the next day. It's not all about finishing one boat, it's about developing a Platform that can evolve as you learn.
