Mark1 or mark2
Iam not certain but I belive Mark 1 is pre 1977 and had keel steped mast.(mast goes through cabin top to floor of boat) Some of these had optional pop top liftable cabin roof. Mark 2 started in 1977 and had mast on cabin top. I am certain that Mark 2 has much better designed interior as far as feeling open and usable. Mark2 has foldig table on bulkhead, Mark1 has permanent table with two small benches. Not positive but I think Mark2 has anchor locker in bow, dont think most Mark1 did. Happy sailing Lance

Never heard of the "Mark" title
I have not heard of the designation of Mark 1 or Mark 2, and I have seen a lot of literature on the 23's. I own a 1973 still very seaworthy, and it is a joy to sail. The difference is the year; what year is yours? I agree with the previous post that there are definitely 2 generations of the O'Day 23, splitting in the mid-70's. The boats are nearly identical from a distance, the very first boats had a much smaller forward porthole, but that changed in the early 1970's. The sail areas are only 1 SF different, and the ballasts are within 50 lbs. The key difference is that the shoal-draft keel of the early boats had a bolt-on cast iron unit, where the later generation had an integral keel. There are several other small differences; it is a matter of taste as to whether you think they are improvements or not: EARLY - Actually 23' long, with 2'-0" draft, board up. Board cranks up with a wire pendent on a reel in the table post. Has double lower sidestays either side of the upper sidestay, all on separate chainplates at the rubrail. Backstay has a high split about 4' above the transom. Mainsheet blocks are mounted on both aft ends of the coaming, reeved through the end of the boom, and a swivel cam cleat on the port side. Cabin has the table on the starboard side, with bench seats fore and aft, converting to a double bed with table down. Galley is all on the port side, with a deep pilot berth under the cockpit. It has an anchor locker and bow pulpit. The boat was offered in 3 cabin models: fixed roof, convertible roof, and pop-top. The first two had a roof stepped mast with hinged tabernacle. The convertible style allowed the roof aft of the mast to raise up to 6'-4" headroom while at anchor. The pop-top has a keel stepped mast, and the entire roof raises up, riding up the mast. An early model also offered a walk-through transom on the port side of the rudder. LATER - Actually 22'-9" long, with 2'-3" draft, board up (same centerboard fits both). Board pulls up with a rope into the cockpit. Has upper and lower sidestays on the same chainplate through the deck. Backstay is a single part to the transom. Mainsheet block is shackled to a plate on the backstay above the tiller. Cabin has a bulkhead mounted table, with a split galley aft. It has the anchor locker, bow pulpit, and many later models had a stern rail. Has separate cockpit storage locker for the outboard gas tank. Only offered as a fixed roof, as far as I know. My family enjoys the sidetable interior. I have never had chainplate leak issues common to the later model and the 25. I prefer my mainsheet system. I do wish I had the gas tank locker. The stern rail is a good add.

Note for Keith
Keith A note for Keith I have the version with the main sheet attached to the backstay. I have been unhappy with this and am looking for a better system. I would like to know more about your mainsheet arrangement with the possible thought to change mine to be like yours. Could you send more details and maybe two or three pictures to me at dhesme@insightbb.com. I know of at least two other 22 and 23 owners who are also interested in making an improvement in this area. Regards, Dave
