You are making things too complicated. Exchange or sell the underpowered DC charger you have now and replace it with one that is not underpowered...one that will allow for charging your batteries at a good rate while you are using most of your house DC loads. For a twenty something foot boat I would be looking at something no less than around 50 amps DC. That would be a typical minimal size for your sized boat.
