Regular Wave Responses and Stability Characteristics of a Systematic Series of Unappended Swath Designs,

Abstract

The effect of several hydrostatic parameters on the stability characteristics and regular wave responses of Small Waterplane Area Twin Hull (SWATH) ships is investigated. Only one parameter is varied to produce each configuration. For head and following waves the effects of longitudinal center of buoyancy, separation between the longitudinal centers of buoyancy and flotation, longitudinal metacentric height, waterplane area and variation in lower hull diameter are investigated. For beam waves the effect of transverse metacentric height is studied. For the values studied all hydrostatic quantities except longitudinal center of buoyancy are shown to have a significant effect on the motions. (Author)
