I use the "non stock" system. It uses a Nacra style bar for over rotation w/two cleats on main beam. For rotation limiting, there is a small block tied to the bar with a line run through it. The two ends of the line go into the center of the tramp pouch and through a gromet to the bottom of the tramp. From there, they split and go outboard (one starbord, one port) there they go through the tramp again (just inboard of the shrouds), through a cheek mounted to the deck, through a small cam cleat then they both tie together near the center of the boat. This way works great, I find it the easiest to work, most adjustable and reliable. Skipper or crew can work it from the boat or on the wire.
