Abstract: A watercraft comprising a compressed air propulsion system is shown and described. The watercraft includes at least one propeller operatively connected to an air motor. Storage tanks supply compressed air having a pressure of at least 2000 psi to a pressure regulator that reduces the pressure and supplies air to an air control valve. User controls adjust the air control valve to adjust the flow rate of air to the air motor which in turn adjusts the direction and/or speed of rotation of the propeller. An on-board air compressor energized by a plurality of lithium iron phosphate batteries provides air to the air storage tanks when the pressure falls below a specified value. In certain examples, the electric and air propulsion system is used to replace a fossil fuel engine in an existing watercraft and can remain at sea longer than the existing watercraft.

Abstract: In a jet-powered boat wherein water is drawn through an inlet opening in the bottom of the hull, accelerated by an impeller pump and discharged through a jet nozzle to propel the boat forwardly, the improvement wherein an afterplane is secured to the boat rearwardly of the inlet opening, the afterplane being positioned so that the water flowing past the hull just below the layer of water taken into the inlet opening flows past and in contact with the underplane to exert upward forces thereon.
