Im new to sunfish racing, and Im haing a hard time finding a picture/diagram of the "JC Strap" and also, a cunningham diagram. Any help and added input is always appreciated.
I don't think I saw anything about a JC strap, but www.sunfishclass.org has ways to rig a cunningham under tips and tricks on the left side of the page. I think that you'll need a race sail to run a cunningham, don't know if a stock sail can handle it.
