I have a newer Sunfish that I sail all the time and recently a relative asked me if I would sell his older sunfish for him. This is no ordinary Fish!! It is a 65 and has been hanging in his garage for 43!!! years. It is in pristine condition and has probably been used 5 times-it weighs 131 lbs and the hull looks new. It does not have a trailer-what should I ask for it? Thanks for your help.
