I have no idea if the boat is ok or not, but the question that keeps coming to my mind is "why?".
Seriously, why start from a doubtful position when a bit of patience is bound to turn up something less uncertain. No matter what you buy there are going to be some undesirable surprises, why start off with the probability of increasing those risks?
I doubt there is a great risk of regret in not buying
We took three years to find our boat and not a day goes by that I am not glad we did not rush the process. When I think what we looked at and might have bought I get cold shivers.
