Interesting choices. I think for cruising the Caribbean the idea of ventilation would be a big box to tick too. Also, the keel description is a bit archaic. As an example the Amel keel is a bolt on, but it is not to bolt to hull it is to a stub. WAY stronger than just bolt on and much better in some ways than an integral keel of unknown substance that might expand, rust, or otherwise fail. That integral keel discussion never gets enough attention.
People conflate to many elements of the discussion. I’d rather an Amel bolt on keel any day to a integral keel with concrete or rusting iron in it.
On the CT56 I’d like to point out a few things. First, the one rounding Hatteras was being done single-handed. I had actually spent time on the boat before it left Norfolk with the sailor in question and do consider him a friend (we just sailed in a flotilla in the Bahamas together). He really is a sailors sailor.
Several boats on that passage had issues and the weather window was considered good by many. More importantly after it was brought into Beaufort I was on the boat and actually was the one who moved it between marina’s with my sons. So I got to see the damage first hand. The new owners I’ve only chatted a tiny bit with but they seem like fine folk. I’d say that CT56 is one tough as nails boat.
They also are found in many anchorages of the Caribbean. I’ve also chatted extensively with Bob Perry the chief curmudgeon of architects. He has a lot in his book on boat design about the boat. I can’t believe you did an entire segment and never mentioned the most infamous owner was Bob Bitchin (another acquaintance) and owner of the “Lost Soul” Anything that can survive Bob is built like a tank.
If you have a dream about sailing around the world the CT 56 will help you do that. And, teach you about soft decks, leaky windows, random broken things, and in general turn you into an amazing shipright pretty darn quick. My choice would be the Ovni. Numbers tell a story but very few boats are just the numbers.
