Abstract
The accurate practical evaluation of the high-speed catamaran resistance in still water is a crucial problem in naval architecture. Even if a lot of research was carried out in this field, the accuracy of the speed-power prediction depends on the hull shapes and the typical restrictions of the methods. The present paper examines the results obtained using an in house computer code, developed in order to calculate the round-bilge catamaran resistance. The wave resistance coefficient was calculated on the basis of typical regression coefficients provided in the scientific literature. The computer code may be used in order to estimate the high-speed round bilge catamaran resistance in initial design stages.
