Re: Please tell me this is a nutty idea so I will stop looking at this boat.
Did the owner know the head gasket was blown when he accepted the offer from the first buyer? If he did and didn't disclose that I would start to look at the boat with an electron scanning microscope. There may be other issues. The boat does look clean, maybe a bit too clean. Did the blown head gasket allow coolant into the chamber which maybe lead to hydro locking and possibly to a bent rod. Sails in good shape? I'd low ball it by about $5k, he doesn't want two boats.
No such thing as a free cat, and that goes for boats as well.
