first time owner long time O'Day admirer from my years in Annapolis; Just "aquired" poorly maintained 25Ft with all but 12 inches of swing keel snapped off. Have done alot of work on all types of boats over the years, but never anything to do with swing keels. Help... boat is currently anchored, needs rescue! Looking for resources on aquiring new/ good used swing keel and advice on procedure for replaceing same;
