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.

[ What is claimed is:] [1.] A retractable suspension and wheel apparatus for a watercraft, comprising:a selectively retractable nose wheel mounted within a nose wheel cavity of a hull, towards a forward end of said hull,a laterally spaced apart pair of rear wheels mounted, within aft wheels wells in side walls of said hull, on first ends of elongate members, said elongate members pivotally mounted at second ends thereof to said hull within said aft wheel wells, said elongate members selectively pivotable by actuation of selective actuators so as to rotate said rear wheels between an elevated storage position within said aft wheel wells and a lower extended and locked position,wherein said elongate members are selectively pivotable by means of suspension struts pivotally mounted at lower ends thereof to said elongate members and pivotally mounted at upper ends thereof to said selective actuators, said selective actuators actuable so as to selectively drive said upper ends of said suspension struts from a position forward in said aft wheel wells, wherein said elongate members are rotated up so as to retract said rear wheels into said elevated storage position, to a position aft of said second ends of said elongate members wherein said elongate members are rotated down so as to extend said rear wheels into said extended and locked position and said suspension struts are releasably locked in an over-center position in said aft wheel wells.
