Second Chance,
You will love these boats, overall quality is excellent!
A few other pointers I may suggest:
-Inspect the hull to deck joint for separation. Tartan used aluminum flange and stainless screws for this, arguably not the best method due to seizing, although there are NO known reports of any separation.
-Boats built before 1982 (?), the deck fittings were attached directly through the cored deck, after 1982 (I am not positive I have the right year) Tartan used solid glass for factory fittings, of course a PO could have attached fitting after where there is coring.
-Look closely for hull blisters, likely not to be anything serious, just cosmetic. We found hundreds of pea sized cosmetic blisters after the first spring we purchased the boat. A soda blasting exposed them all and were not picked up by the survey. This information would have made for a nice bargaining chip for us. In addition, the hulls were cored with end grain balsa...so you'll want to check for water intrusion. Again there are no known reports of structural issues related to the hull of the T37C...now the 3700, that?s another story
We have owned our T37 (#358) for 3 seasons now. No complaints, some usual maintenance issues (the W50 has a fuel leak) & upgrades, and other than the blister repair I did two years ago we have had nothing but great sailing days.
Congrats on considering a wonderful classic sailing yacht.
