Yikes...time for an inspection.

I will tell you this, though, most of the ones that I have seen are pretty firmly affixed to the hull and not oriented so the pivot axis is in proper orientation with the mast. If they're setup wrong, the misalignment will create large bending stresses on that fitting with a lot of cycle loading (resulting in fatigue). I noticed mine were not aligned properly when I got my boat so I rotated the deck fitting so the stay master would swing toward the mast and the pivoting function would absorb any misalignment (they were both 90 degrees away from this orientation and it took some effort to turn them).

I'll be disassembling to check that fitting before our next sail. Thanks for the heads-up!
