I'm with Yorksailor and others who would want to have a working center board on this model boat since it was designed to be sailed with one. If I were considering buying this T 37' I'd deduct the estimated cost of restoring the center board to functionality from my bid price and it may not be all that easy or cheap to do.
Tartan made quite a few boats with center boards. Is this the model you are looking at: TARTAN 37-2 Sailboat details on sailboatdata.com
My boat is a smaller, older sibling of the T 37' but the Tartan 27' is a full keel design and the centerboard really reduces our leeway when going upwind when deployed.
