Abstract: A high speed hybrid marine vessel with integrated hydrodynamic lift-generating, roll stabilizing and pitch controlling wings, or hydrofoils, operable in two distinctly different modes, namely a hydrostatic stable low speed mode, featuring a positive GM-value with at least three submerged hull elements; and a hydrostatic unstable high speed mode, featuring a negative GM-value with only one submerged hull element, the hull elements being integrated to the vessel via an integrated deck construction connecting the side hulls to the main hull.
