  • Using the LPB pump as an air compressor.

    Can you use the LPB pump to recharge the gas bottle then use it to blow the ballast tank? I know you wouldn't get as many "blow" compared to using Propel but you can refill the tanks everytime you surface.

    You'd need a huge air bottle. You can't use the standard gas backup canister. You'd also need a solenoid or other valve to seal the tube after the pump shuts off. I bet you'd get 1/8 of a ballast tank's worth of air.

    Not feasible with onboard components, I'm afraid, but I like how you think!

      Ha-In Groton (Johan) traveled with a 3000PSI scuba tank to refill the accumulator in his 7ft Beast!

        Wow! You could easily put an onboard compressor on that thing.

          Was hoping to have a system that fits inside a 2" SD.
          Definitely for bigger boats.

          Maybe (a modified version of) this can be used onboard subs.

            Did some rough calculation (Boyle's Law P1V1=P2V2) with the 2" SD. To fit the volume air inside ballast tank into the gas canister would require approximately 60-70 PSI. Way beyond the capacity of the snort pumps ( rated to only 15-17 psi).

            You could use a lower pressure but you would need a bigger storage tank. A smaller tank would entail using a more powerful pump.

            Definitely for those with big boat.

              If nothing else, this is a fine thought exercise.
