This paper refers to an unconventional passenger vessel which matches hydrofoil and SWATH principles in order to achieve high transfer speeds, low environmental impact and reduced wave washing phenomena. This new, hybrid vessel, called ENVIROALISWATH, should be able to provide high performances, manoeuvrability and controllability typical of hydrofoils and, at the same time, good sea keeping qualities and low installed power, typical of SWATH solution. The design has been developed through a joint research program between Rodriquez Cantieri Navali S.p.A of Messina and the University of Genova. In this paper the final verifications of the structural design are described. After a preliminary scantling of the main cross section, carried out by applying existing HSC Rules, the structure has been refined by separate numerical models of the hull and of the submerged body. The gathered information have been collected in order to setup a finite element model suitable to simulate the behavior of the structure as a whole. Starting from this model subsequent implementations have been carried out improving the investigation of stress and strain distributions. Local and global effects have been considered. For the numerical detailed investigation the two FEM codes Maestro and Ansys have been used and the results compared, so verifying their reliability.
