Charging 24 volt system with 12 volt charger. As far as charging boat batteries on the water test your system on land and always use the correct size fuse and proper gauge wires safety. You can use a 24 volt charger or a 12 volt two bank charger. The 24v systems that employ 12v batteries can be recharged with a 12v alternator by simply being plugged in like any other 12v battery.
