Greetings All; I've been using the Harken Clew Hook with Rooster Strap for a month. Today, after rounding the downwind mark, went back on a starboard tack in about 10 knots of wind, and the clew hook detached. I was able, with some difficulty, to get it back in and finish the race, sadly last. Has anyone experienced this? What do you think caused the failure? Thanks.
