Just a thought… If you could recreate the problem you might consider borrowing a similar block from a neighbor and trying it. If the problem disappears, a replacement block would solve it. If it does not, at least you eliminated a bad block/cleat possibility.

But I did not think it would pull out under shock load any more than under continuous tension. The free end is not moving since the traveller was pinned in the middle. Garhauer has no clue either so far. The only thing I notice is that the block tilts as the tension comes off as the boom reaches the midline and then it snaps up again as the boom hits the other side. It is that shock load at the end that pops it out of the cam.

Traveller is on the companionway. I used a 7/16 sheet and don't recall any trouble, but the cam block was on the bottom and the line could not fall out. Could the sheet be catching on something or someone or is the sheet is too small?

I have a double ended system, with a 5:1 on the traveler with a Garhauet triple block with cam cleat then led forward to the mast and back to a winch on the cabin roof. The advantage is that I can quickly adjust in lighter airs with the traveller system and winch the main in heavy airs at the other end. It works fine except I had a problem that many times (not always) when I jibe, the main sheet pulled out of the cleat on the triple and the line ran out until it hit the stop knot. It happens so fast that I really could not see why this was causing this. It would happen even when the traveller car was stopped on both sides and there was loss of tension on the sheet prior to the jibe. The only thing I could see that might be an issue is that the block has the cam cleat on the underside so perhaps it was “falling out” of the cam during the jibe. We tried to make sure the sheet was not dangling down into the cabin, but it still seemed to happen. As a last resort, I ordered a triple from Garhauer with the cam on the upper side and installed it recently. I was in a race yesterday in heavy air, and it happened again with the new version of the block and cleat. Does anyone have any insights on what is causing this and how to stop it?
