<p>The present invention provides a new and unique enhancement device for marine propulsion of marine craft and displacement vessels advancing in seawater to facilitate operation at higher speeds with lower-powered engines, resulting in lower initial cost, higher cargo capacities, lower fuel consumption and much higher profitability. The device comprises a conduit having a first end and a second end, an opening provided in the first end, at least one discharge vent provided in the second end and a gate provided in the second side, wherein the gate is adapted to repeatedly move between a first position in which the second side is fluidically open and a second position in which the second side is closed. The device can be incorporated in a new vessel during construction or retrofitted as a stand alone unit in older vessels.</p> |
