Abstract

An elongated ski boat is provided for producing a relatively small, well-defined wake and a relatively smooth working table. The boat comprises an elongated hull which includes a bow, a stern, a port side, a starboard side and a transom. The hull comprises a starboard keel panel and a port keel panel, each of which extends from a location above the water line near the bow to the stern of the hull. The keel panels join one another at a center keel line to form a V-shaped keel section having a starboard edge and a port edge. The V-shaped keel section defines an obtuse angle at the bow which progressively increases to an angle of slightly less than 180.degree. at the stern. A starboard chine panel and a port chine panel are each joined to the respective edge of the keel section, extending forwardly from the stern to a location above the water line near the bow. Each of the chine panels extends downwardly from the line of connection with the associated keel panel at an acute angle with the horizontal which angle progressively decreases to about 0.degree. at the stern. A starboard side panel and a port side panel connect to the associated chine panels and extend upwardly and outwardly. The transom attaches to the starboard and port keel panels, chine panels and side panels at the stern of the hull.
