It's hard to imagine but there's a community of about 500 boaters in the area who are year-round liveaboards, many winter on the water year after year. I wouldn't even try this if I wasn't living aboard myself, which I'm doing now. You are correct that you need to constantly monitor everything.I can't imagine doing this in Toronto. I have no experience in this, but what happens if there is a power failure, or any of a million other possibilities to knock out the system? How much time do you have before that lake crushes your hull like an egg shell? How often do you visit your boat in the dead of winter? If you can't detect and correct a problem in a lot less time than it takes to freeze up, I think I'd get a very good insurance policy.
Great suggestion. I've been waiting a few days for them to accept my registration. Are you on the forum and, if so, could you give them a nudge for me? Thanks!
