I had a friend who, tried to, do something similar. Unfortunately he knew almost nothing about boats and bought a boat that ended up costing him almost as much as he paid for it in repairs, sank once, and that he eventually sold for a tiny fraction of what he paid for it a couple of years later having only been able to spent a few hours at sea.

So I guess my point is, if you're going to do something like that, make sure you buy a really good boat.
