Stability and roll motion of fast multihull vessels in beam waves

In this article, the results of a numerical and experimental study of the stability and roll motion of different advanced multihull vessels are presented. The study concerns the effect of the lines, transverse and longitudinal spacing for two catamarans – one with rounded bilge and one with a hard chine, an innovative bulbcat hull in comparison to the basic catamaran and two trimarans. The experimental results in beam waves are analysed by the means of different mathematical models.
