Claim:
A vessel comprising: a hull designed to be propelled through a primary fluid, the hull having a surface that is at least partially submerged in the primary fluid; and at least one entrainment device attached to the surface, each of the at least one entrainment device including: an inlet through which a first portion of the primary fluid flows, the first portion of the primary fluid entering the inlet through a first opening and exiting the inlet through at least one nozzle; a flow diverting member located downstream from the first opening of the inlet, a second portion of the primary fluid flowing over the flow diverting member; a second opening that enables the secondary fluid to flow into a first region, the second opening being located at or downstream from the flow diverting member and between the surface of the object and the second portion of the primary fluid; and a free surface located where the second portion of the primary fluid abuts the first region; and wherein the at least one nozzle directs the first portion of the primary fluid through the free surface, so that at least a portion of the secondary fluid is entrained into a portion of the primary fluid wherein the flow diverting member comprises a trailing edge and the at least one nozzle comprises a lowermost portion, and the trailing edge of the flow diverting member and the lowermost portion of the at least one nozzle are spaced apart.
