Entirely reasonable for liveaboards as you are, not so much for a weekender I think.
I don't liveabord, but I sail and anchor out for one or two nights two or three times a month if not more.
When we bought our boat in 1998, I went through the standard "which is better, separate or combined I/C?" analysis and installed a Freedom 15. My PO had put a microwave in but since we aren't dock queens it did no good for us without an inverter. It's a mod sine wave, works the microwave just fine.
I find it amazing that inverter discussions seem to almost immediately migrate to COFFEE discussions. Look, if you have what you like that makes YOUR best coffee, who is ANYONE to complain about YOUR choice?
Your boat, your choice.
Maybe when Maine Sail writes his "How to wire an inverter" article, he'll touch on the coffee issue and provide you all with an answer.
We use a melita filter with stove heated water into a Coleman SS thermos. But I reheat it it in the microwave, all I have to remember is to NOT put the metal coffee cups in the darn microwave.
Also use it for the drill, computer, heat gun...limited time on that sucker!
If your battery system isn't set up for the loads, then fix that end of the equation. People who buy inverters but are afraid to use them??? Get another battery.
The inefficiencies have come down, but with a healthy electrical system, it really shouldn't be an issue at all. I agree, not all 12V equipment is as good as 120V, but I don't have a TV on my boat either. I read a lot and watch nature. I also have a radio to listen to ball games. It's 12V, car stereo, it doesn't make coffee.
