The response characteristics of a systematic series of seventy-nine 30,000-ton appended SWATH configurations with lower hulls having elliptical cross sections have been investigated analytically. Three values each of waterplane area, strut length, longitudinal center of buoyancy, and longitudinal center of flotation are used to define the hullforms. For each configuration, root mean squared values of heave, pitch, relative bow motion, and absolute stern motion are presented for a unit significant wave height and a range of modal periods for head and following seas at four speeds. Performance assessments in which the highest significant wave height for which several seakeeping criteria are not exceeded are given . Trends among the performance assessments for the various configurations are noted and provide a seakeeping reference for the designer for potential 30,000-ton SWATH ships. Author
