I have owned a 1975 Tartan 30 tall rig for 2 years, hull 275. This boat was a one owner boat sailed by an avid racer. It has good deck equiptment such as barient 26, & 10 winches . strong mast and rigging . the hull and deck are solid. The rudder was soggy and needs replacing.
I resealed the chain plates and only one had leaked to the point where there was a very small amount of rot in the sourrounding deck
Look around and for $12,000 you can find a well taken care of boat a few basic repairs should be all thats needed, then you can spend your time sailing rather than working on the boat, I am planning on learning to sail for 5 years or so before i venture down the coast , then after a few years , maybe across an ocean.
