ABSTRACT:
A boat in accordance with the present invention includes boat hull and a pair of elongated members or skis or a modification to a standard boat hull to add on a dual ski attachment to make it a dual ski boat. The hull has a port side, a starboard side, an aft and a bow. One of the elongated members is adjustably mounted to and extends along the port side of the hull and the other of the elongated members is adjustably mounted to and extends along the starboard side of the hull. Each of the elongated members is adjustable between a first, retracted position wherein the member is retracted into a first recess in and is substantially flush with the hull and a second, extended position wherein each of the members extends down below and at least one foot behind the aft of the hull. The elongated members each have a forward section and a rearward section. The forward section tapers to a forward point located above the rearward section and has a triangular, hull-like shape which is larger than a piece of the rearward section of comparable length. The elongated members also may have a wedge extending away from the bottom surface of each elongated member and located adjacent an inner edge. The wedge extends along at least a portion of the bottom surface.
