Wing keels
George,Catalina made wing keels from the 1987 to 1991 model years. R.W. is right when he says they are expensive- when I was looking,the few I saw were $10,000 to $15,000 plus trailer. I bought an O'Day 26 instead, which has more head room than the 1987-88 Catalina models, has a pull out double berth in the cabin, 2.5 foot shoal keel with swing down centerboard that drops to 6 feet. The O'Day 25 is very similar, but not quite the headroom. Many more of the O'Day 25's made though. Both have similar lines to the Catalina.
