We had the lines with hooks (chicken lines) on the Tiger we just sold and liked them a lot. Only used in really big swell and wind. In "normal" conditions it was not used. Only, only only hook it to the trapeze handle and NEVER the trapeze harness.

My plan on the Infusion is to make a cup that inserts into the hole at the end of the crossbar so the hook will hide inside when not in use. So as not to accidentally grab one of the sheets. That does not happen too much but thought it would add a bit of comfort.

Our system was a line from the rear of the boat with the length we wanted it to be, then put a bungee on that line into the rear crossbar so it can be sucked in with no slack.

We also had footstraps that were added before the line. The first ones were attached from the back of the rear crossbar to the hull. That was not far enough back and we added a second set to the very back of the boat. Kept the first ones on. Sometimes I sail with people that are not comfortable getting all the way back on the boat so they can use the front ones.

Later,
Dan
