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. The direction and the power for the apparatus is provided by a unique combined propeller/rudder unit whose thrust and steering direction is controlled by the bicycle handle bars. The bike will be kept in an upright position by a support yoke which will allow the rear wheel of the bicycle to rotate. The hull or hulls of the apparatus will be of sufficient length and width to provide stability for the apparatus in rough water conditions.
