Abstract
A boat hull is provided with a series of steps which are angled toward the center of the hull from the front to the rear of the hull. In order to permit easy riding up of the hull on the steps progressively, as the speed of the hull is increased, the steps are carried over the side of the hull above the normal water line of the hull when the boat is stationary. As the power is increased, the wetted area of the hull is progressively decreased and the friction of the hull and its resistance to forward motion is progressively decreased as the hull rides further out of the water. The principles as described above are applicable to airplane hulls, the wheels of amphibious vehicles, and other variations of normal type boat hulls.
