Having once owned an O''Day 23 hardly makes me an expert, that said, these boats were your average garden variety coastal cruisers. From my experience, they used some chopped glass in areas of the boat rather than mat, I had two stanchion bases poke through the deck, the guy that repaired it discovered the abundance of chopped glass. The standing
rigging was adequate but not overly robust, I lost the mast on a blustery day, probably my fault, I do like to go fast! They were not particularly sophisticated boats, somewhat utilitarian in design and build quality. They could probably be best compared to the Beneteaus, Catalina and Hunters made today, that is to say without the glitz of the stern rail puke
seats, cup holders,
furling everythings and cockpit picnic tables.
Depending on how you intend to use the boat will determine whether it is a suitable for you. My guess is that the keel is lead rather than iron but I wouldn''t bet the farm on it.
It sounds as it you’ve inked the deal, enjoy your new vessel.
