The hydrodynamic analysis of a new semi-small waterplane area twin hull(SWATH) suitable for various applicationssuch as small and medium size passenger ferries is presented. This may be an attractive crossover configuration resulting from the merging of two classical shapes:a conventional SWATH and a fast catamaran. The final hull design exhibits a wedge-like waterline shapewith the maximum beam at the stern;the hullends with a very narrow entrance angle, has a prominent bulbous bow typical of SWATH vessels, and features full stern to arrange waterjet propellers. Our analysis aims to perform a preliminary assessment of the hydrodynamic performance of a hull with such a complex shapeboth in terms of resistanceof the hull in calm water and seakeeping capability in regular head waves and compare the performancewith that of a conventional SWATH. The analysis is performed usinga boundary element method that waspreliminarily validated on a conventional SWATH vessel.
