Re: [PSUBS-MAILIST] enquiry - Surface Propulsion
Hi, I think if you're going to be operating a small sub you would most likely need to have a surface tender boat near by, that boat could supply the sub with a battery charge. Another option would to moor the sub over night and have a generator in a small boat charging all night; large capacity gas tank. Or another option that would be logistically unrealistic, would be to have a second battery pod that could be changed out. Or have a second sub that was all charged up, just trade subs and charge the one not being used.
