ABSTRACT:
A marine vessel is constructed with a submerged front rotor/turbine that shields the vessel hull from water motion induced resistance force to a degree without significantly increasing the vessels water resistance while abstracting hydrodynamic energy from the vessel motion displaced water that would otherwise be dissipated/lost and couples or connects the resulting rotorary energy through mechanical or electrical means to assist in driving the vessel.
