The O'DAY 12 had a sail that used a sleeve over the mast, Sails originally came from Neil Pryde. I would think any good sailmaker should have the dimensions and specs for the sail, just be sure to ask for the O'DAY 12 and be sure they don't get that confused with the Widgeon. I hope these pictures may help others (and maybe even you?) in this search. For parts, D&R Marine (ww.drmarine.com) might have info on parts, best to actually call Rudy Nickerson there for best results, (508) 644-3001 H was Parts Dept. Manager for O'DAY and now D&R is his little "Mom & Pop" shop selling O'DAY parts. The setup was pretty basic, so if Rudy doesn't have a source for mast parts, he may know of another boat similar enough for the rig parts to be useable. Rig is sort-of a simplified, smaller version of a LASER-type boat.
