What is the working pressure of Saturn boats in terms of PSI? Do I need a special pressure Gauge?
Maximum air pressure is 3.6 PSI. It is not necessary to have an air pressure gauge to inflate Saturn boats. The boat tubes are equipped with Safety valves that will prevent over-inflation. In general, when you feel that boat tubes/floor are hard to the touch, and it becomes difficult to pump any more air in, that means the boat is ready.
