We've had a few close calls jibing in heavy weather and rounding up towards oncoming boats while trying to release the sheet.
This Spring, I purchased a Harken trigger cleat. It had a much wider bolt spacing than the cleat fitted to my Hexaratchet, and calls to APS and Harken revealed that the trigger is only meant for a double-block setup.
Nevertheless, I was able to add shims and mount the cleat successfully. I'll try to remember to take pictures tomorrow.
The advantage of the trigger is that it has a cam action that releases the locking cams when the sheet is pulled further into the cleat (upwards in the case of the mainsheet).
Since mounting it, we really haven't had the heavy weather to test it, but it does release smoothly under moderate loads.
I'll give you an update when we've really had a challenge.
