ABSTRACT:
A boat is disclosed having a hull with improved operating characteristics. The hull includes a central sponson and outer sponsons on each side of the keel. The sponsons include chines which extend from the transom to the peak of the bow. The chines have ski-like flat portions for providing lift. Between the chines and the keel are a pair of arched tunnels. The chines, the bottom edge of the keel and the gunwales all meet at the peak of the bow. The chines, the keel and the tunnels are all linear and parallel between a mid-section of the hull and the transom.
