That sounds wonderful, but the line I'd always heard was "A boat is a hole in the water you throw money into" - that is, they are expensive to maintain. How do you avoid that?
That's no different than working and paying someone else to do it, economically, but I imagine you enjoy it. More power to you. :-)
Actually, my family owns a country home (far from anywhere; land tax is ~zero) that's also next a fjord. As in, a meter and a half from the water. We've got a floating dock.
I've been wondering about how to maintain it, now that our patriarch is getting too old to do so. The main issue, really, is how to get back and forth - I'd love to live there semi-full-time, but realistically can't do so in the winter, and the roads are getting worse every year now that all the farmers are gone. Using a suitably large boat seems like an interesting option, and would give me the choice of living closer to some town if I need to work closely with people on some project.
If you have some figures - how much it actually costs, etc. - that'd be great. I certainly wouldn't mind doing maintenance myself, but I expect it still won't be free. Also, what model boat do you have?
Sounds like a great project!
Now if you live on the boat you are using it which would make it more economical however I'm sure the upkeep and fuel costs more than a house would.
