I like the thought of them but never owned one
While I think a centerboard would be a nice configuration, offshore work would worry me. If you have ever been caught offshore in severe weather, you appreciate a boat that is simple and strong. I have some reservations on centerboard boats. I almost purchased a Catalina 22 centerboard boat but found a better buy on a fixed keel hunter 25. Several owners had to redo the centerboards on several 22 including one who had lost the board completely. Three keel boats over 35 years and have never had a keel problem so I will probably stay with fixed keel boats. The real question is can a centerboard boat handle offshore abuse. I am sure their are some around that can ie Bermuda 40 etc that make it work.
