I had one on my old hobie 20. THat thing released on its own all the time, I took it off and went back to the cam cleat. It was the older style with the nylon cam so the newer alloys could be better, I dont know.

With a spinnaker rig I would be real hesitant. The last thing I need is for the traveler to dump on its own downwind in a blow.

I probaly error on the side of keeping the traveler and main too tight right now but ????

Always borrow money from a pessimist. He won't expect it back.
