So I tried lots of different positions for the jib tracks and blocks and the cam cleats. Finally concluded that the only position that made sense was midships. Hmm.
Went back and looked at the plans. Sure enough. The original called out an optional pedestal with a snubbing winch that sits on top of the centerboard trunk.
Thought about it for awhile--three hours--while I did some plumbing work. I can make this pedestal out of teak or mahogany a lot faster than I can make a mold to create a fiberglass replica. So guys, help me out. How high should the snubbing winch be above the centerboard trunk--or how much lower than the deck? Pictures and explanatory text appreciated.
