I think CaptForce is most when it comes to using a generator. I know trawler
friends that use household appliances
and so the generator helps reduce the use of the inverter
since those use AC power. When they anchor
out a lot they need the generator to charge up the batteries. Some trawlers like to anchor
out often too. If you run a generator during high energy loads you'll find your batteries are easier to fully charge. If you stay anchored in one spot you can just run the smaller generator engine
instead of the main engine and often get better fuel
efficiency since both burn fuel to make electricity. They both make noise
but perhaps a generator would be less noise
and less heat.
The most energy demand on most cruising boats is the fridge! They consume more power than anything else on most boats. More than everything else on our boat. Our A/C needs shore power
. We have solar
too and it stretches how long we can go before running the engine. I had a wind
gen on the last boat but I find I choose not to anchor where the wind
is blowing strong. They can make a lot of power under way but most have a noise factor. These days solar panels
add a pretty good boost and are silent with costs coming down. Eliminating the use of power is the first step and maximizing solar
should be the second step. More power use just adds more work for the crew (me). You need to understand how much power you need and how you use it and when you use it to get a grip on making all your energy production balance out every couple days.
Solar and wind cost a lot but the trade
off is you get more peace and quiet. If that isn't a goal they are a waste of money
as a generator is cheaper. At night we all want peace and quiet and a generator is neither.
