Sailors/Boaters, what are 'rubber fenders' on a boat/yacht?

Question

What does it refer to in the following sentence?

"Kelly scrambled along the portside to deploy his rubber fenders."

Answer 1

Favourite answer

They are something like heavy duty rubber balloons - or even old car tyres - hung on the sides or docks or boats, to cushion any impact and prevent damage when a boat is tied against a dock wall.

The size depends partly on the size of the boat/ship..

Answer 2

they're round rubber tubes that hang along the side of the boat to protect the hull from hitting the dock

Answer 3

Rubber tubes filled with air that keep the boat and dock from scraping each other.

Answer 4

The link is to a Taylor Boat fender boats carry them inboard so they can be tossed over the side (tied on of course) to keep from rubbing up against a dock.
