Been there... done that and going to do it again.
We (just the wife and I) lived aboard for the past 2 years and spent 2/3 of that time working from anchor
as well. When we weren't anchored out (we anchor 3-5 nautical miles out normally), we were docked for the winter in the snow, ice and temps that approach and dip below zero. We also cut, split and hauled our own wood which was our only source of heat.
rides back and forth are brutal, boring and time wasting - I agree and have complained before about it. Even worse... when you have to row 3 miles because your outboard
We also had no hot water (didn't need it), but we did have the pressure water.
You know what? Despite that hardship (which makes you a stronger person in general), we loved the life. We are currently on land now after having sold the boat because we have to save up some money
and switch boats (ours was too expensive and we had a loan).
I do have one comment from experience. You need to devise a better way to charge your batteries. Your charger
is WOEFULLY inadequate if you are running the generator
for that long. You should be able to fully charge up your batts (to a reasonable amount) in no more than 3 hours. I did it in about an hour, but recently (with a battery
monitor) found out I was running the genset way too much. I only have to run it 3 hours twice a week now that I can see the state of the battery charge. Get a bigger charger
that will get those batteries charged faster. With the price
of gas, you are spending more on that genset than a charger would cost. You could save a ton of $$. Also, the genset will last much longer with a better charging
PS: Can't wait to get back to that lifestyle! Land is making me feeble and weak! ha ha ha
