ABSTRACT:
An elongated, rectangular, open chassis frame preferably carries fore and aft hollow containers fixedly mounted to the frame and within and protected by the frame, beneath the wood decking. Flooding of the aft containers causes inclined submergence of the dock trailer unit to facilitate loading of a boat onto the wood decking fixed to the top of the chassis frame. A demountable wheel assembly includes a pair of elongated sliders which are bolted at selected positions to beams at the sides of the chassis frame to adjust the wheels to the center of gravity of the boat when trailed by the unit. Winch driven anchor bars adjustably vertically mounted to at least the rear corners of the chassis frame allow adjustment to the dock-trailer unit vertical height to jack the rear of the dock-trailer above the water level to fix the unit as a dock subsequent to unloading of the boat.
