Looking to buy older, lower priced 34-40 foot sailboat
I feel you will be out of luck. In my search for a low price, 30+ foot sailboat, I found that once you pass that 30 foot mark, the prices really jump, or should I say leap! Also note that I said "low price", not low cost. Plan on pumping quite a bit of cash into the boat after the purchase if you buy her at a bargain basement price. Trust me, I haven''t been there, I am there!
