- Mainship 34 Pilot
I have a 34' 2002 pilot. The hot water heater is located under the forward Dinette seat. Mainship did not utilize the tank het exchanger. The only resource for hot water is 120V power. We like to anchor more than stay at marinas. I'm not a fan of cold showers. We did the Loop last year with this configuration. I do have solar (600W) and I do have a 3000W inverter. Twin engines that can help with battery charging while under way. Our resource last year for hot water was while running with engines and solar with good output. Turn the water heater on. This uses about 70amps. A lot of 12V dc power. Between the 50 amp alternator that puts out about 35amps and the solar controller which averages 35 amps when in bulk charge we could maintain battery Voltage but barely. We have a refrigerator \, freezer, electronics ...... all using amps too. This method worked but it is not efficient. We do not have a generator installed. We do carry a 2200 watt Honda that will power the hot water heater but I'm not a fan of using it when we are underway or if the anchorage has a number of boats anchored. I'm do not like running it because of noise. The efficient way to have hot water is to use the engine closed cooling and the the hot water tank heat exchanger. The issue I am having is finding a path to run the hoses. Mainship build has solid bulkheads glassed to the hull so passage forward is limited and the areas of access seemed to be used. This is a twin engine model so the 250 gallon fuel tank spans the full beam of the boat forward of the engines. If you have this model twin engine and have closed cool water hoses going to the water heater can you advise me as to where the hose runs are? Thank you.
