Can't you ask some one at the beach? Or would you need to first return to the 80s to find cat sailors on the beach?
Any way when i put that system on a hobie 18 which has the main beam flush with the hull like the prindles, i tied a turning block to the lip on the outside of the hull in front of the beam. Just drill a hole in the lip. maybe seal it in case you hit bubbles in the lam.
After that line was stolen off the boat i switched to a righting pole. Was doing more solo sailing and didn't need a chicken line, but did need a lever to re right.
