ABSTRACT:
A multipurpose boat has a central cavity formed therein; a lid for closing the cavity; transverse grooves formed in the top surface and aligned grooves formed in the lid, the grooves functioning to strengthen the boat and being curved to discharge water; and elastic cord mechanism associated with the grooves for securing the lid closed. The boat top surface further is strengthened by longitudinal supports secured to its underside. A mast for the boat has a goose neck fitting associated therewith for rotatably mounting a sail carrying boom thereon. A combination of a tiller carrying a cleat device is provided for steering and maneuvering the boat when rigged with a sail. The cleat device defines an outwardly opening V-shaped slot with rope gripping walls for holding a rope set therein. The cleat rearward portion adjacent the slot exit slopes or curves forwardly and downwardly to provide a surface around which a rope inserted in the cleat slot may be pulled to set the rope therein. The cleat may be made of a rigid, yet resilient material to permit the setting of a rope deeply and tightly in the cleat slot.
