Changing subject, I agree with some other posts that a good battery/inverter setup, adequately sized and with appropriate charging capability, can be much better than a genset in many applications.
I've believed that for quite a few years but then I live where I have no need for A/C & heat. I also have a propane stove, so with my refrigerator being 110V (small) as is my ice maker, the only 110V requirements left are the batt charger (turned off when I'm away from shore power) two lamps (40 watt bulbs) 4 X 110v receptacles. (1 in the head, 1 in the state room and 2 in the galley. After cruising for at least an hour, the hot water is really hot and lasts 24 hours at anchor. (Hot shower in the AM, no genny or inverter needed.)
Having a 3000 watt inverter, and 3-8D AGMs for the house, my only requirement for a genny is to charge the batts. Since we never go off shore power for over 3 days,but if we ever do
, enter the Honda EU2000 for charging the batts. And with just a hot water heater needed after 24 hours, the EU 2000 will handle that.
A long time ago, I was cruising in the Sea of Cortez and was anchored at Juanita Cove. I met a guy, his wife and their Golden Lab. (Bear) They were running a 38' Down East style boat and were on a 1 month extended tour of the Gulf of California. I marveled at the beauty of their boat and they finally offered to give my brother and I a tour. Although the boat was impressive on the interior, the thing that stood out the most was that
it was totally a 12V boat! There was not one 110V requirement on the boat and no genny to charge the batts. They had solar collectors on the roof and a cruise generator to keep the batts topped off.
Now, I know that in many climates, this system will not work as people do require a/c and heat at times. The point (after this long winded post) is that you don't have to set your boat up with similar power systems that your home has. After all, we go boating for a little release from the day to day and maybe for some "soft adventure."
