During the 1992 America’s Cup event, Bill Koch’s America 3 syndicate introduced a material subsequently called Cuben Fiber. Round yarns, or tows, of fiber (Dyneema, carbon, aramid) are spread out into a flat tape of side-by-side filaments. At the time, Cuben Fiber was used in laminated sails. Then, in 2001, Swiss sailmaker Gérard Gautier imagined such flat tapes put to a different use — one that would get rid of the film in the laminate. In Gautier’s version, the tapes were impregnated with a thermoset resin that, once catalyzed, would hold its shape despite heating or cooling. The Alinghi syndicate tried Gautier’s technology in the run-up to its successful America’s Cup defense in 2007.
