I just bought a 1986 O'Day 31. I received a lot of paperwork with the
boat, but no owner's manual. Is there an owner's manual for this boat? If
anyone has one, I would like to get a copy.

I have to replace all the running rigging on the boat. The rigging is very
worn, but it appears that the size of the lines are as follows:
Reefing lines: 3/8"
Jib Halyard: 3/8"
Main Sheet: 1/2"
Main Halyard: 3/8"
Can anyone confirm that these are the right line sizes?

Thanks for any assistance.
