TWO CONVENTIONAL TRAILER WHEELS ARE CONNECTED BY COLLAPSIBLE LINKAGES TO TWO DRIVE BLOCKS MOUNTED TO RECIPROCATE IN OPPOSITE DIRECTIONS ON THE DRIVE SCREWS TO SHIFT THE WHEELS INTO AND OUT OF THE WHEEL WELL THROUGH OPENINGS IN THE BOTTOM THEREOF. A CONVENTIONAL TRAILER HITCH IS MOUNTED ON THE FORWARD END OF A RETRACTABLE BEAM THAT RECIPROCATES IN AND OUT OF A HOUSING ON THE BOTTOM OF THE BOAT. THE BEAM IS CONNECTED TO THE DRIVE SHAFT BY A THRID DRIVE SCREW WHICH ADVANCES OR RETRACTS THE BEAM IN UNISON WITH THE TRAILER WHEELS. SLIDABLE COVERS ARE PROVIDED FOR CLOSING THE WHEEL OPENINGS IN THE WHEEL WELL, WHEN THE WHEELS ARE RETRACTED.
