don't forget the sails. I would bet most of the mid 80 H22s still have original sails, many of the ones in this area still do. Mine did when i picked her up in 2010. They will most likely be blown out, and sail terribly. It was a WORLD of difference when i replace them. But a new set also costs an additional $1400. Also don't forget the o/b motor. if it needs to be replaced that can be another $1500. Will this boat be in the water full time (as mine is) or on a trailer (ask Charlie/SeaTR about his)? You don't need bottom paint if its on a trailer, but you do when its in the water.
Not to scare you off, I love my H22, we have spent many weekends and nights out on it. Its a great size for the three of us (me, wife, and teenage daughter). Its easy enough to sail that my niece can sail it at 9y/o, once the sails are up.
The comments above are all good. just things to keep in mind when negotiating a price. These are solid little boats. I got mine for next to nothing, but like Charlie's it was pretty close to being scrap. I have replaced all the electrical, running rigging, the keel, the sails, new motor, cockpit cushions (for the admiral), and many other things. I have probably spent two or three times the purchase price fixing things.
