ABSTRACT:
A self-propelled water craft includes a hydrofoil-bladed wheel assembly which allows an individual to propel the water craft through the water at a relatively high speed. The assembly comprises an open frame with attachment means for securing to a stern of the water craft's boat hull, a drive shaft rotatably mounted on the open frame, at least one bladed wheel permanently secured to the shaft to rotate with the shaft, and a hydrofoil mounted on the open frame directly below the bladed wheel. The blades are mounted on the periphery of each wheel and are angled backwardly. The blades are also curved. As the blades move through water they force water flow over the hydrofoil in a manner which propels the water craft forwardly and provides the proper lift to the water craft so as to lessen water resistance against the boat hull.
