Analysis of the sea keeping behavior I: waves of small amplitude

This work deals with dynamic behavior of the ultimate design configuration of the Sea-Bus: the sea surface is characterized by waves of small amplitude. Considering the shape of the bodies involved, i.e. thin profile section of the airfoils, and the high speed (elevate Froude and Reynolds number), it ha been used a three-dimensional inviscid rotational model in the frequency domain.§at the air-water interface, suitable boundary conditions are defined, which link the velocity potential functions of both domains. Starting from these conditions and adopting a boundary integral formulation, the equation systems in the two fluid domains are solved using a proper iterative algorithm.
