Rigging specifications

[Dave Mauney]

I am trying to intrepret the standing rigging spec. for an O'Day 35. This has to do with the pin center length (PCL) measurements. The Manual reads the "PLC is from the bearing of ball and cup(s) to: Pin in turnbuckle with standard toggle or center of upset toggle 'U'. All PCL with turnbuckles at 2/3 open."

So I think what I am reading is the distance is from the base of the ball to the center of the standard toggle pin closest to the turnbuckle? For the life of me I can't find what an "upset toggle "U" is. Am I right on which pin they are talking about for the standard toggle and what would they be talking about for an "upset toggle "U".

Thanks Much
Dave
