  • Patent number: 4263866
    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.
