Patent ID: 8449340

Claim:
A personal propulsion apparatus for controllably gliding a rider over a water surface, comprising: a buoyant body unit, a power unit and a thrust assembly with at least two independently pivotable thrust nozzles, the power unit is capable of generating and delivering pressurized water to the thrust assembly; a substantially hollow intake unit having a receiving portion positioned at an angle to a directing portion, a height adjusting arrangement is formed within the directing portion; a delivery conduit providing communication between the intake unit, the power unit and the thrust assembly; the height adjusting arrangement comprises a plurality of air relief openings formed in the directing portion, so that upon elevation of the air relief openings above the water surface air enters the intake unit and power unit causing decrease of the thrust; wherein during the motion of the rider over the surface of water the intake unit with the height adjusting arrangement remain submerged in to the water, so the rider is being self-propelled and glides over the water surface, upon a further lifting force being produced the intake unit with the height adjusting arrangement is elevated above the water surface causing entry of air into the intake unit and power unit, resulting in decrease of the thrust and lowering the height adjusting arrangement below the water surface into the submerged position, so that the rider assumes the longitudinal motion over the water surface.
