Abstract
Presented is an efficient propulsion system for boats that operates, with the boat going forward at high speeds, with its fluid accelerating rotor operating on an air and water mixture. The rotor is disposed, as seen in vertical transverse planes of the boat, at least in its majority to sides of hulls of the boat. The lower periphery of the rotor is proximal a keel of the boat when the boat is moving forward at high speed thereby insuring a shallow draft situation. When the boat is going in reverse, the rotor is supplied only with water so that it can act to pressurize the water in its discharge. The pressurized water from the rotor discharge is then reversed by one or more reversing buckets. An inlet flow adjusting system, inlet flow directing vanes, and air fences are options. This efficient new propulsion system for boats may be applied to all manner of boats including monohulls and multi-hulls.
