发明名称 Ultralight/compact airboat apparatus
摘要 An ultralight/compact airboat construction weighing less than five hundred (500) pounds yet stable at high speeds of, for example, in excess of forty (40) mph is provided. The hull provides a unique configuration having a parabolic flat portion positioned upon the bottom of the hull and communicating with the transom wherein the widest part of the parabolic flat-shaped portion communicates with the transom. The hull gradually decreases in width and depth beginning at the midpoint of the vessel and proceeding forwardly toward a blunt nose.
