Actually, when a fender is bolted to a dock, it is a bumper. When a bumper is hung over the side of a hull, it is a fender!Fenders....aka bumpers...the dock protectors. I have always called them bumpers, but God help you if you called them that and someone heard you lol
I generally do not stop what I am doing to pull them in till I am out of the harbor, would mean I am not at the wheel. If I have guests, I have them do it when we get off the dock and are clear of the boats next to us.
Easy to forget, hard to not know once you hit speed.
