There's Food and Drink and Fuel in the Tank

���The submanne is about to return to its tender to take on needed stores. The crew simply lassoes the floating buoy, connects an electric cable, and by means of a control mechanism inside the submarme, causes motors within the tender to unwind the anchor cables and allow them to come to the surface. A member of the crew then scrambles over to the tender opens a hatch and takes out any package stores desired. Oil and fuel are transferred by pumping them through a hose. The oxygen is also piped across. If desired, a man may be left on the trailer permanently, to raise or lower it by means of hand winches when necessary
