23.5 Swing Keel
I have removed the centerboard in my 23.5 water ballast. I'm not sure if it is similar or not. I removed one large bolt in the cabin floor. I then took a yellow tow strap around 18 ft long and rapped it around the bow. It looked as if it would slip so I took some anti skid foam padding from the department store and put a 2 ft strip of it under the strap at the bottom of the bow. I put 2 rounds of wood under the stern with some wood wedges and some carpet to support the stern because with the bow up the boat wouldn't set on the trailer bunks evenly. I then used a heavy duty come-along winch puller to jack the bow up in the air enough to lower the center board down and out the front. I had to lift the boat about 2 ft. I was worried I would pull the roof down instead of the boat up in my shop so I put 2 temporary posts from the floor up to the rafters in the roof. I used some kind of metal hangers from Home Depot to secure them. The whole thing got more involved than I had hoped and it looked pretty dangerous. I had to lie under the boat and trailer and jerk the centerboard around to get it out. I was doing it alone at 11:00 p.m. 100 yards + from any people. Without the anti skid foam, it would have been a sure accident. Even with it, it was pretty sketchy. I haven't put it back yet. I hope this helps. It would be worth it to go somewhere and have the boat lifted with a crane from both ends, but I would have them just go a foot at a time and try to catch the centerboard somehow. Other wise it could suddenly come loose and fall from 6 ft up and damage it. Again, this is a 23.5 water ballast. I don't know if the center board is held in the same was as your earlier swing keel. I would call Hunter and ask before trying to do the same thing as I have described. potteryrob@yahoo.com
