On proportions of catamarans and regulation of their stability
Abstract
Catamarans have obtained good reputation as recreational and passenger craft, and are perspective type of craft for the Russian market. Safety of catamarans is proven by the experience on foreign countries including trans-ocean passages. But for catamarans problems exist with their stability regulation; this forces shipbuilders and operators to look for other solutions. Application of criteria for monohull ships dictates proportions of catamarans with which they are losing efficiency and decreasing their safety. The paper touches importance of justified proportions of catamarans from viewpoints of their hydrodynamics and habitability. Analyzed are problems of regulation and existing approaches of specialized rules. In the paper recommendations on stability regulation are presented based on practical experience of the author.
