ABSTRACT:
A floatation device system for travelling across a body of water. The floatation device system includes a spaced apart pair of pontoons with spaced apart elongate front and back crossbeams extending therebetween. A forwards end of an elongate center beam is coupled to front crossbeam, the center beam is coupled to the back crossbeam. A rearwards end of the center beam is rearwardly extended from the back crossbeam. A rear rudder is pivotally coupled to the rearwards end of the center beam. A rotatable propeller is mounted to the rear rudder. A rotatable driven wheel is connected to the propeller by a flexible sheathed cable so that driven wheel rotates the cable which in turn rotates the propeller.
