That’s the issue, the owner had commissioned a hull inspection report only two years ago which reported the issue in black and white. That was the basis for the owner going back to the boatyard for remediation. OK he may have genuinely thought it was now resolved and therefore decided not to disclose; personally I would have disclosed.Dont really think its encumbent on the owner to know about all his boats issues, especially under the waterline, and these things are always degrees of etc.
I always ask for docs at first contact and then ask the pertinent Q's. I think it'd be impossible to prove the owners behaviour unless a previous survey had the problem written up in black ink.
Anyway as many have suggested I’ve walked away and will just put it down to more learned experience in the rich tapestry of buying a boat.
