OD34
I own an '83 OD34. I bought it in '90 and have been very happy with the boat. No hull problems, deck had a lot of voids which were easily found and filled and you should check. I have done LOTS of improvements and upgrades and probably would not be nearly as happy without them - new sails (key to any boat), new roller furling, 'real' traveler, larger wheel, besides electronics, etc. I threw out the carpet and put in teak and holly. The engine, 25hp Universal 3 cylinder, has run just fine and I have had no significant problems. Layout, especially the head and vee berth arrangement, is very nice for cruising. Sails very well - I do some racing and have held my own - good sails are key here. Fundamentally I think you will be very happy with the boat. Any 19 year old boat is really subject to how it's been cared for though, so look carefully.
