The underwater cable burial machine uses a single cable for both towing and lifting. The machine includes a retractable cable, which is connected between a retraction mechanism and the towing cable. There is a cable guide through which the retractable cable passes. The cable guide is located over the center of gravity of the machine. In order to use the towing cable to lift to the machine, the retraction mechanism pulls the retractable cable and the towing cable until the point where the retractable cable and the towing cable meet is at the cable guide. At that point the towing cable will be over the center of gravity of the machine, and the machine can be lifted onto the surface vessel to which the towing cable is attached.
