We have even used sun showers (solar) in all sizes from a quart (squeeze type of hand held) up to the 10 gallon one with a foot pump. Agree that one can get a good shower with 1 gallon if well organized.
We also keep a 3 gallon insectide pressurized spray container in the cockpit for washing off feet and legs (plus the dogs) as we board.
Another rig we have, is a Jabsco diaphragm pump, with about 6 feet of pickup and outlet hose. This has alligator clamps for any 12 volt power source. Many times in freshwater rivers, we just pump the water from the river up directly and wrinse off with it (the soaping phase when swimming). This same pump can act as an emergency bilge or suction pump to get the last amount of liquid out of the cabin, since it is self priming, and will put out a good head of pressure, or pick up 6 feet above the water level.
