I would personally stay away from Ocean Yachts. I grew up on sport fishing boats, the good brands (Bertram, Viking, Hatt, Post, etc) are magnitudes of quality better than OY. Go on the sport fishing forums and see what those guys have to say about OY (ie,
www.thehulltruth.com).
Their quality may have gotten better in the 90's and 2000's - I don't know, since I moved away from sport fishing boats then. But, the last time I was on an Ocean Yacht, I was shocked by how flimsy it was. It was in the early 90's, I was an official observer on a catch and release billfish tournament in Ft. Lauderdale. I was aboard a 65' or so OY, about 3-5 years old - and the thing was literally (LITERALLY) coming apart at the seams. Screw popping out, trim pieces falling off, couldn't close cabinet / salon doors because everything and every bulk head was "floating" inside the hull.
Also the closest I've come to dying on a boat was on that 65' OY, in a following sea. Had a wave catch up to us and broach us, and we got knocked down on our beam ends. The salon windows and flybridge hit the water, and we had a wave of green water poop the cockpit.
And, I can't say I subscribe to their hull designs. They are absolutely flat at the transom - no deadrise - sort of like a Carolina Skiff with a keel
BUT - If you go view this trawler, and it is in great shape, and you don't plan to run offshore with her in heavy seas, and it's a great deal - then I'd say go for it. Better to have a mint condition OY for a steal than a beat up and trashed Grand Banks for big $, in my opinion.
