A new performance prediction method for multihull yachts is described. The methods described here, and performance predictions based on these methods were used in the design and modifications of the 1988 America's Cup Defender Stars & Stripes. The method incorporates the type of solution procedures used in state-of-the-art monohull velocity prediction programs. The various models used for hydrodynamic and aerodynamic forces are briefly discussed. The predictive method is validated using full-scale data from C-Class catamarans, a Formula 40 catamaran, a 75-foot “maxicat”, and Stars & Stripes with a soft-sail rig. Several examples of design studies are presented.
