I noticed some slight scuffing on the fiber glass along the front cleat where the dock line feeds through. I found a product called NoWear Guard that I decided to try out.

These are very thin 316 stainless steel sheets with glue on the back. I used the 6” on the “bridle cleat, and the 9” on the Sampson post cleat. It worked out well as you can see from the picture. They are easy to work with.
If I were to do it again, I would cut out an area for the bridle cleat connection to the fiberglass, so that the stainless could be moved higher on the flat upper edge which would provide more of the flat top to adhere to. So, I will order two more to cut in and fix the slight uplift.
I would cut the Sampson post cleat piece down some, because the metal can’t completely seal against the curvature along the bottom edge due to the multiple curves involved.
