I am a bit confused as to what I need here to get some electric going onboard my boat. I am looking to run a small wet/dry vac, small refrigerator, portable ac unit (or portable air cooler) basic interior and exterior lights, maybe a small stove, laptop and stereo. It seems a noisey generator is not very practical, not to mention it needs to be outside. So I am wondering if a good deep cycle battery with an inverter with do the trick? If so, I wonder how long a 105 or 120amp hr battery will keep me running before I need to recharge. If anyone here has some suggestions, please let me know, thanks.
