I just bought a 1981 Oday 28, and the mainsheet is toast. Traveler is mounted on the companionway step of the cockpit, not on top of the cabin. It's over 80 miles away from me, and I forgot to take mainsheet off of the boat to measure. Does anyone have a length measurement of the mainsheet? Also, any suggestions on the diameter? I was considering 1/2" Sta-set or comparable. Lastly, please advise if you know of somewhere out there in cyberspace is information on ALL of the running rigging specs. It would make my ordering a ton easier. Thanks.
