I recently bought a 1990 Tradewinds 43 that actually measures out to be 47 LOA. Inspection found soft spots near the bowsprit, water intrusion at port lights forward and water damage under door sill of door to sundeck from salon. The big one was the roof over the sundeck. While relatively level (not sagging) when viewing from below, it sagged a lot on top causing rainwater to collect. I had the top fiberglass removed only to find that the glass was not glued to the core - I could smell the resin still. There was a small area of intrusion near the anchor light but that was all.
Mine has Cummins 210 HP - solid performers. Hydraulic steering is great. Keep an eye on corrosion of fuel tank straps.
Can't wait for spring to resume cruising the Chesapeake!
