ABSTRACT:
An amphibious pedal powered sailboat apparatus is provided by the present invention. In one embodied form, the inventive boating apparatus comprises in combination a relatively lightweight boat hull having an upper deck portion, a bow portion, and a stern portion; a front pair of wheels mounted on the hull for steering and to provide mobility of the apparatus on land and a rear pair of wheels mounted on the hull to provide traction and mobility of the apparatus on land; a first pedalling stand fixedly mounted in the bow portion of the hull and a second pedalling stand fixedly mounted in the stern portion of the hull; the first and second pedalling stands each comprising a pair of foot pedals mounted for rotational movement about a horizontal axis transverse to the longitudinal axis of the hull; and drive mechanism for coordinating operation of the pair of foot pedals on the first and second pedalling stands. A unique transmission system is provided wherein rotational movement of the foot pedals by one or more occupants of the apparatus is transmitted to a gearing system and the drive mechanism which synchronously powers a screw propeller and powers the rear pair of wheels to provide amphibious operation of the apparatus. Accordingly, the unique pedal powered sailboat apparatus of the present invention is capable of cruising on water with pedal power of the occupants and capable of land transportation without the use of fossil fueled combustion entines or electricity.
