I have had chicken lines set up two different ways. One, was with an S hook that was affixted to a roller cleat (like used on an adjustable trapeze system. The hook goes to the trap ring NOT the harness. This is a nice system and easy to set up and use, but you need to be careful jibing to hook the S hook to the hiking strap on the tramp when jibing other wise it bounces around on the hull. It works great for distance races, but not so much for buoys. The other plan is to attach to jam cleats to your harness bar (mine are attached to small plates that I had welded to the bar). This way the chicken line just goes into the cleat and when not in use, sucks back into the rear beam with a bungee. A little quicker to use and suits both buoy and distance races. I have crashed while attached to both systems, and neither have hung me like the video.
