Wave resistance of high-length-to-beam surface effects ships

The ACVWAV computer program is used to investigate the wave resistance experienced by a pressure distribution moving at constant speed. Wave resistance coefficients at constant weight and pressure for various length-to-beam ratios are presented. Surface elevations are also computed. Recently there has been an interest in high length-to-beam multipurpose transport surface effects ships. The ACVWAV program can be used to aid in determining the resistance characteristics of such ships. It was used in this study to compute the wave resistance and surface elevations of a pressure distribution moving at constant speed U over calm water for some high length-to-beam ratios. This study is an example of how numerical techniques can aid in predicting the hydrodynamic performance characteristics of proposed ships.
