Abstract : A computerized routine for synthesizing a Small Waterplane Area Twin Hull (SWATH) ship has been developed. From simple design parameters a hull can be represented geometrically and resistance and propulsion estimates can be made. The results of a sample exercise of this routine and comparison of model experimental results for SWATH III and SWATH IV are presented. The synthesis routine successfully ranks these two hulls on the basis of propulsive performance. (Author)
