Abstract
Abstract This invention relates to a new manually propelled watercraft with a hull either solid or hollow to act as a pontoon and platform with a paddle wheel, to provide a means for propelling the watercraft, detachably secured to the hull by means of two so spaced arms attached to the hull by means of laterally spaced pivot pins thus allowing horizontal movement of the arms thus providing one means of guidance. Another means of guidance is accomplished with ropes or wires attached to either a rudder at the aft end of the hull or to each arm at the forward part of the hull and running through the hull to the operator.
