With the lightest catamaran hulls relative to their volume of any boat available, Performance Catamarans' Nacra 20 is a recent, high-tech design, relying on computer generation for some of its design elements. Its asymmetric spinnaker, carbon fiber mast, and canted hulls are part of the boat's standard set-up. Other features include a double trapeze, carbon daggerboards and rudders, and a main and roller-furling jib that are both made of mylar. Tom Roland designed the first Nacra catamaran in California in 1975, a creation that would spawn a series of different-sized boats all bearing the same name. Nacra-series boats win worldwide multihull races, and four members of the series, including the 20, have been lauded as "Boats of the Year."
