I'm not getting a good vibe from this boat. Have you looked at a lot of them? Here in the Chesapeake Bay area prices are still softening, and there's no way any reasonable person would put this 9.2C on the market at 20K. There's one in the water locally that's been used but not abused as a live aboard on the market at 15, and they've admitted to being flexible at that point. If this had anything major going for it, like all new sails and rigging, or a new engine, or Scarlett Johannson was servicing the brightwork, I could see it. Of course, if it tugs at the heart strings, you may not have any choice. But it does surely scream "survey me!" Have you run the engine? Looked at its fluids? Tested the electricals? Water system? Bilge pump(s)? Head? Will the yard let you keep it there while you work on it? How's it smell below decks? If there's a major mildew issue, getting it and its smell out of all that fuzz, without replacing everything, ain't easy. Anyone else you have to make happy with this purchase? How's that person feel about it?
In case you haven't guessed, I'm a professional-grade newbie. My 9.2A is my first boat and, if my wife has anything to say about it, my last. It was in decent shape when I bought it, at a pretty decent price. I've sailed it nearly the length of the Chesapeake, have it in the water 3/4ths of a mile from the house, and I'm spending my available free time replacing and repairing bits on it, most of it long overdue. I'm having great fun doing that, but then I've been able to sleep aboard it without my eyes swelling shut or my having nightmares about imminent hull failure.
Do you know how long the boat's been on the market? Any paperwork you can rummage through to see what sort of care it had or when it was last used?
Tell us exactly where you're located. Maybe there's a list member who's in the area and could look at the boat with you, or at least help you find a good surveyor. I know it's tough to spend that money, when it could go for a shiny new chartplotter or some mold-free cushions, but, in addition to all the info you'd glean, it'd help in the bargaining process. Is this, perchance, yard owned?
