<rant>[For crying out loud! They couldn't have at least straightened up some before taking the listing pictures?!? I mean, come on! the broker's coat and portfolio are just dropped on the chair. That's a little bit of a red flag there just by itself.] </rant>
That's a good price, but you can see subtleties that look like they might need attention. The sundeck teak looks good (finished anyway), but the engines and general engine room condition (of what we can see anyway) looks a bit unloved. Remember, this boat is going to take a lot of regular and new maintenance. Every 40+ y/o boat will, but these older trawlers are especially susceptible to thinks like soft decks, leaky windows, smelly hoses, and sketchy wiring etc. It's all good if you go in with your eyes open and expect it, but don't expect a turn-key experience. Not for this price anyway. It's priced to sell for a reason and not because the owner just feels like helping the world out.
If you can afford it and are seriously considering it, get thru the survey and see where you are, but prep yourself to lose that money. A good survey on these trawlers could have a very long list of "stuff". It will sometimes scare people away... but some can see past that and well have proper expectations set. I have even paid a surveyor (with the owners permission) just do a walk-thru before an offer is even made just to scan the overall condition in a high-level look without digging down into a full-blown survey. Some will do it... some won't.
Anyway, I don't want to be too opinionated about a boat on pictures alone, but I always look at listings with a grain of salt until I get onboard. Still, old boats are old boats. It's not about the yard or the brand... It's about its history and how much love (READ: maintenance) it received.
Good luck!
