Methods and tools for structural design and optimization Structural design of a medium size passenger vessel with low wake wash

Catamaran has comparable hydrodynamic performances with very large platform area. Nevertheless it shows unsatisfactory wake wash performances and seakeeping features in rough sea.

SWATH has very good manoeuvrability and seakeeping characteristics together with a high payload vs waterline area ratio. Otherwise SWATH configuration is subject to deck slamming and green water phenomena and requires very high installed power for high speed.
