Just wondered what the issue was.
The issue was a ring used on the lower clevis of a head stay on a Pearson 36. The ring was undersized and was pulling back through the hole due to wear.
It was caught in time, only because of a badly worn furler line that needed replacement, but it snapped when trying to remove it. One or two more sails and it would have been gone. This was actually a combination of two problems. The clevis was slightly too long and the ring pin too small of a diameter. I suspect that when flying the spinnaker or running down wind the head stay tension would soften and allow the pin to move in the hole.
A properly sized ring pin (hard to find) or a properly sized cotter pin wouldn't have worn due to the lack of "slop" in the hole however the clevis still should have been about 1/8" shorter. That clevis was re-drilled and cut shorter by a machine shop and a correctly sized cotter pin installed and it was never a problem again.
