[quote=zAr;456113]T.... the engine was showing paint bubbling in places, I don't think it's been properly maintained, owner says he changes the oil and filters once in a while and doesn't know how many engine hours are on it - so I expect a full engine overhaul is needed. He also doesn't know how old the sails are, just that they're in fair condition, so I'd expect to have to replace them all. Doesn't know how long his anchor chain is?! Doesn't seem like the sort who keeps logs...or he's hiding something.
.../quote]FWIW, a simple compression test of the W33 will tell you what you need about the engine, other items to look at carefully are the mounts, fuel tank rust (very hard to see!!!), hot water tank rust.
I would agree to be dubious of any boat owned by someone who can't provide precise answers about maintenance history and equipment upgrades. A boat owned by a clueless owner will be rife with unpleasant surprises.
Certified...in several regards...
