It's to the point that you probably need to start doing something about it.
When you see glass threads it's time. It can absorbe water with the damage in the pictures. Clear glass is ok to a point.
Cleaning with a medium wire wheel, lightly sanding and feather edgeing then (if no cloth in needed) paint with resin. Scuff and finish off with paint or Marine-Tex.
A roller in conjunction with the centering post may reduce the friction wear to that portion of the boat
