I use a combo of the flat fenders attached to the dock, plus large round tube style bumpers hung from the cleats.
X2 Different tools for different jobs.
Fenders as defined above. I like these for when I pull up to someone else’s dock, tie up to another boat, remote fishing, etc. Bigger the better but there will be a sweet spot for every boat. I like when they are long enough to protect the freeboard but still have a few inches above the waterline.
If it’s my dock I want the dock itself to have something that is tall enough to be above the rub rail. This way when I pull in there’s no fuss or hassle to attach bumpers. They don’t shift, move in the wind, or rub on the paint with waves.

Couldn’t find a pick for what we have. Essentially we have the dock posts that stick up a few feet. Then slide in a pvc or a specialty plastic bumper over the post. This way there’s nothing to pump and lasts years.
If you need, you can get extra brackets to add more posts. Tip – do this now before the ice melts Soo much easier mount on top of ice instead of waders or floating on a paddleboard. Family got a different boat and adding in one extra post in the middle of an 8′ dock section.
