I agree with John. From everything I've read so far the general concensus is that refitting a boat can cost much more than you think, even more than the purchase price, depending on what's wrong to begin with.
I asked about your travels because I use to do a great deal of hiking in the mountains and deserts of southern California. I absolutely loved it! The only cure for a roving foot is more of the same! Good luck in your search for your boat as well as pursuing your adventures!
