ABSTRACT:
A circular boat comprising a pair of generally dish-shaped members connected together in opposed relationship. A cockpit region is provided abeam of the boat and an outboard motor is operationally but fixedly mounted in a motor well behind the cockpit region and within the perimeter of the boat. A pair of flat skis is rigidly mounted to the bottom of the boat hull. The hull bottom is also provided with a planar section which defines a forward planing surface substantially coplanar with the skis. When sufficient forward speed is reached, the boat rises and planes on the skis. Steering is achieved by shifting of weight by the boat operator over one or the other of the skis, the boat being rudderless. The boat is also equipped with fins projecting laterally from the hull bottom whereby the operator may step onto the hull deck while the boat is underway to dip a fin into the water and thereby cause the boat to make a turn.
