Sorry Progresst, haven't been on in a while. Yes, Commodore changed the rig to a fractional from the masthead that Columbia had. I'm not sure of your sail number but probably the production number of your boat. I think that was pretty close to the end of the manufacturing run. Your sails are most likely original and therefore have lost their shape. I have a lot of info, the original brochure, some of the design drawings etc for the boat. Will see about getting them to you.
