I think I would call C.Raymond Hunt, Assoc. in Boston, Massachusetts...Do you have a copy of the pen and ink drawing from the 322 manual? The manual had both side and front views as well as cross section drawings of the keel. A lot of time has passed since the development of that series of boats by
O'Day....you might also contact Rudy and D & R Marine in Assonet Mass.....it appears I have misspelled
the city but give it a try as well.
