THE ROLL STABILITY OF AN S.E.S. IN A SEAWAY

This paper reports on a series of investigations on surface effect ship stability in a seaway. Open sea tests with several radio- controlled models with adjustable center-of-gravity height demonstrated that capsizing in a seaway occurs almost exclusively when the craft is beam-on to wind and sea. Beam-to-sea tests were also carried out to study the causes of capsizing. This extensive series of tests showed that all capsizing incidents follow the same sequence of events, and that, if the center-of-gravity height is below a critical point, capsizing in normal sea states is virtually impossible. The author indicates that the experimental techniques developed in the research can serve as the basis for establishing practical roll stability criteria.
