ABSTRACT:
A retractive suspension for a boat is provided whereby retractable wheels and associated struts and suspension may be retractably mounted within compartments which are open, or may be opened, outwardly of a hull of a boat. A front wheel assembly is housed retractably within the bow of the boat. An opposed pair of rear wheels are mounted within corresponding compartments on either side of the aft end of the hull. The wheels struts and suspension, both fore and aft, are selectively pivotable from a stowed position within the compartments or wheel wells to an extended and locked position extending outwardly of the boat hull from the wheel wells so as to support the boat on the wheels when on land. The struts and suspension are pivoted by means of threaded rod or spindle or elongate screw which is rotated to slide one end of an arm snugly mated within a corresponding slide such as a box beam.
