  • Patent number: 5387140
    Abstract: The floatation apparatus for use with any standard bicycle (either single or tandem unit) a catamaran or pontoon hull with a tubular structure to support a standard bicycle. The front wheel of the bicycle will be removed and the front fork will be attached to a support that is connected to the directional control system in order to provide a steering mechanism. The novel steering mechanism has the fork connected to a steering control pulley. An adjustable line is connected to the steering control pulley on one end and wraps around a steering pulley that is attached to the rudder at the rear of the apparatus. By reversing the direction of the steering control lines and passing them around a number of idler pulleys, the operator will turn the apparatus in the direction he or she turns the bicycle's handle bars. The rear wheel of the bicycle will rest on a rotating drum that will provide power to a drive propeller.
