I am looking to buy a 1982 Santana 22' It has been repaired from a hole in the hull and a hole that occured from the keel running into a large rock off of a point. The owner is selling the slip with it, whick costs $500 per year. He is asking $6k but that seems high to me. This is my first time looking into buying a sailboat rather than the ski boats I am used to. Where is the best place to get some info on what this boat is actually worth?
