A Modest Budget Cruiser
Early 1980''s Odays (like Pearsons of this same era)are hard to classify. In many ways these were nice middle of the road boats. They do not offer especially good performance, build quality, or seaworthiness but they were inexpensive, and were better than many others in their price range built during that era. They were built in the day of the extensive option list and so hardware can vary widely in quantity and quality on these boats. They offered simple workable interior layouts with moderately good workmanship but without some of the niceties and closer fit found on better boats of that era. They were a little behind the curve when it came to engineering (which was taking a big step forward in terms of intenal framing systems during that era, a big step that Oday never took.) I have some exposure to a 30 of that era and to 28''s of that era. Deck core problems seem to be a little more common on Oday''s of that era than on some of thier peers, and this is also an era when blistering was very common.
I guess my only other concern with the Oday 34 for your application is that these were not all that robustly built boats and if I understand your prevailing sailing conditions you are sailing in some pretty heavy going much of the time. I would think that could take a real toll on a boat like the Oday.
