Re: I am 26, and seriously considering moving aboard with my girlfriend. Any advice?
I'd double check the finances, considering that the boat will lose value over time. Unless you have a short (equals high payment) mortgage, what you owe will match what the boat is worth. You may not have any value when you sell the boat to get a down payment on a house.
Coupled with this is the timing. Your money doesn't come out of the boat until you sell it, which will get in the way when you find a house you love for a good price. The house seller isn't going to wait 3 to 9 months while you sell the boat.
Other than that, I love the idea.
People sense change the most. (A hand in warm water will start to not notice the temperature.) Start with a smaller boat and quickly move up to bigger. It will seem like quite a treat, and be a happy time.

The best minds discuss buckets. I don't know why. It's a mystery!
