I have '79' O'Day 27'. I'm looking for a tuning guide for the rigging. Is ther such a thing? Or does anyone have any suggestions. We are interested in racing only as a teaching tool for my wife. We'll be racing in the cruising fleet on the Wed. night club races only. Just for fun. I'm a retired racer and like to have some performance in the rigging. HELP please!!!! Allen Hale
