I finally found the listing. It was listed a few years ago at $120K, now it's listed for $59,000. Big drop!
https://yachtworld.com/boats/1989/antigua-csy-44-3247730/ If it is in great shape that's a helluva price. But...
Interesting that the best photos of the boat in the listing (the first and last one) show the name as Camperdown, which is the old name under a prior owner, so you can be assured that those beautiful pictures on the listing with the shiny hull and sails are NOT CURRENT.
That is the first "buyer beware" flag.
The deck is still teak and in fairly bad shape. By now most people have pulled up their teak decks and fiberglassed the deck. Teak decks are beautiful when new, but they tend to leak.
You need to ask about the rigging. When was it last re-rigged?
The layout looks identical to a Walkthrough, and that was our boat. It's a great layout. I don't know a lot about Antigua construction, though.
Make sure you get a survey!
Good luck!
