They are excellent boats. Designed by Lyle Hess and very capable sailors. You got the boat very cheaply, so you need to be prepared to spend some money on her as there are doubtless a fewe things that will need attending to. Get a survey done so that you can prioritise things and get the important stuff done before the merely cosmetic.
An excellent boat though, and if you maintain her well and keep her tiddly you'll probably end up able to sell her for more than you paid.
