I used to do the same sort of thing on a previous boat. 1700 watt inverter and a 10 liter heater, almost like a flash water heater. The boat did not have fresh water cooling on the engine, so the engine could not heat the shower water. Its 55 amp alternator drove the inverter when I was motoring. Worked perfectly.
