ABSTRACT:
A water borne craft includes a smooth rounded elongate sailboard type hull of little depth. The hull tapers down in width and in depth from its middle towards its ends and has smooth upper and lower surfaces. A cockpit extends downwardly into the hull from its upper surface to provide a craft usable in canoe mode. The craft also includes at least one removable reversible insert which fits snugly in two modes into the cockpit. The upper surface of the insert in one mode, being a paddle-ski mode, has recesses to accommodate the buttocks and feet of a paddle skier when the craft is used in the paddle ski mode. The opposite surface of the insert is uppermost in the other mode, being the sailboard mode. The opposite surface has structure for mounting a mast so that the craft can be used as a sailboard in this mode.
