If the cup is tight and won't rotate, the action of gybing the sail may
loosen the universal in the mast track. This of course depends on the type
of mast track, and universal you are using, but a single bolt type universal
in a slotted mast track can be loosened by this. I would verify that your's
rotates at the bottom after it's been tighted down in the mast track. I prefer
to have rotation at both ends. It doesn't take much to loosen the uni in the
mast track, which may either completely unthread and come apart, or just slide
to the back of the track, and pull out.
