BTW I sailed a 49er as a crew recently, and the #1 annoyance was the trapeze system where the ring is pulled down by the shock cord. Not only it is pulled down but when you stand up the ring height at standstill is lower than the hook on your harness. And you spend your time running around standing up on those boats! So you end up having one of your hand just to keep the damn ring from falling of. Considering you need at least 3 hands and quick feet to manage the crazy amount of unstable sail area this didn't go well really.

I mentioned to the boat owner that IMHO those were rigged incorrectly, but it seems the norm in the skiff world: .

Miss the hook on a cat you have half a chance to recover as long as you grab onto something. Miss the hook on a 49er you take a bath and the boat capsizes instantly.
