What I dislike about fenders mounts that a fixed to the boat are that docks and other boats aren't always the same. IE: docks can have things that stick out in different locations, and boats other than pontoons aren't always straight sided. I prefer to be able to place the fenders where I need them when I need them. I prefer to use an easy clip on my fenders, and we actually use three different types of fenders depending on what we are doing. From your straight tube like fenders which are most common, ball type fenders, to the Mission fender tube. We go to a large number of lakes with our boat so we ended up using a lot of different docks and do a lot of type ups with different sizes and types of boats. We have these for easy adjustablilty and placement locations of our fenders for where we need them when we need them. And one stays on each fender when we store our fenders.

Not bashing the installed fender mounts, just found that they don't work for us and there are other options.
