Wave resistance for high-speed catamarans

摘要

The object of this study was to investigate the wave resistance component for high-speed catamarans. Two methods were applied: the slender-body theory proposed by Michell [Philos. Mag. 45(5) (1898) 106] and a 3D method used by Shipflow~(TM) (FLOWTECH, Shipflow~(TM) 2.4, User Manual, 1988) software. Results were obtained for different types of twin hulls and attention was given to the effects of catamaran hull spacing. The study also included the effects of shallow water on the wave resistance component. Special attention was given to the height of waves generated by the craft to ascertain effects on river banks.
