I do! Do you know what year the boat is, and don't worry about being too specific, not much changed over the 1963-85 production run. The mainsheet was changed a bit, but yo ucould basically rig any year model using the same diagram.
If you want more complete info, I have created an expanded version of the original O'DAY-supplied rigging manual for the Widgeon, covering the full production run. Contact me direct for ordering. However, I am willing to answer questions here as well! I have included my Mainsheet and Jibsheet diagram below along with a page from the 1966 O'DAY instructions.
