ABSTRACT:
A recreational vehicle for transporting one or more riders upon a body of water with power supplied by the rider(s) to both a pair of front and a pair of rear wheels which have sufficient buoyancy to support the vehicle and rider(s), preferably with all non-rotating above the surface of the water. One or more gear members, disclosed in several embodiments, are mounted on the vehicle frame for rotation by the rider(s) about an axis parallel to and intermediate of the front and rear axles. A device is provided for transmitting rotation of the gear member(s) to the axles and wheels in one or both directions. In alternate versions, the left and right wheels on one or both axles may be rotated independently for steering.
