With properly sized..
With properly sized, read very heavy, bottom chain, that is 1.5 times the depth at MHW, there should be little to no wear. I have my old 400 pounder sitting on the dock and it was 8 years old when I went up in mushroom weight, for a new boat, and the eye has almost zero wear.
In 90% of weather the bottom chain is what's holding your boat, if it's sized appropriately. It is my guess that the majority of permanent mooring systems use drastically undersized bottom chain compared to what they should.
If you wore out your mushrooms eye your bottom chain was way to light or you have 30-40 knots fairly regularly..
Unfortunately most areas of the country really don't understand moorings like they should. In Maine we have folks who survive, via a proper mooring, on remote off shore islands, year round. What we know about moorings up here has been learned over decades in severe winter storms.. The bottom chain is but one very important component in a total system that has to work in harmony. If you wore out the eye there was something wrong It was most likely lack of sufficient bottom chain weight.
