I looked at a wellington 47 once a few years back. They were made in Jacksonville florida I believe and internal fit and finish varied a bit from boat to boat. Flat decks and a swing keel.
Fuel tanks were cast in fiberglass 2- 200 gallons plus a few hundred gallons of water. The one I looked at was interesting, but ALL the systems were shot and the boat had compresson post issues on both masts. The hull is solid fiberglass and fairly sturdy though. But I still think about that boat sometimes.
Best of Luck in your hunt.
