ABSTRACT:
A pontoon boat having a support framework that includes a number of telescoping cross members that laterally extend and retract to vary the width of the craft. Included tires rotate into and out of ground contact to permit towing without the need for a separate trailer. A motor or hand crank controls a longitudinal lead screw mounted to a reciprocating trailer tongue. Lateral control arms pivot with motion of the tongue member and laterally displace longitudinal side rails and flotation pontoons. A deck and handrails are raised and lowered as the framework reciprocates between travel and flotation positions. One of the sets of telescoping cross members separately rotates the tire support assemblies. A deck control assembly controls the alignment and separation of the deck at a longitudinal seam.
