I am looking for a used Main Sail for an O'day 25' center board boat until I can come up with the cash for a new set of sails. The old sail measures 8' 2" at the foot and 24' at the luff. I think the full keel boats had a larger sail and I don't know if I could use a sail from a keel boat or not. Anybody ever tried to use an O'day 25' keel sail on an O'day center board boat? Any help would be appreciated.
