A structure or framework, referred to as a nacelle secured to the deck of a boat, ship or other water-borne vessel. Within the nacelle a heavy-duty axle or shaft is mounted, supporting a beam that is balanced horizontally on the axle. The beam has further axles equally spaced towards each end of the beam, to which force transfer mechanisms are attached by way of revolving linkages. The force transfer mechanisms are further attached to slide mechanisms positioned above and below the force transfer mechanisms. Power inducers are attached to the horizontal beam to either side of the axle or shaft.
