Anyone has improvised shock absorber for boat lines?

My dock was damaged last winter.  Wind/wave was so violent that the boat ripped off the piece of 2x8 board that the cleat is attached to.  For this upcoming winter I want to put in some shock absorber.

But as with anything marine, this is a bit pricey.  And the ones I looked at does not even list how much force it can sustain.

So I am thinking, can I improvise my own shock absorber?  Maybe hook up a small tire?  Anyone has tried to create your own boat line shock absorber?

And best of all, "No batteries required"...

Looks good.  Will give that a try first.

Shocklines are like $70...

Accompanied with a bumper. Or even a throw out tire from a shop. I would imagine a tire might leave markings on a boat though.

……boats are expensive……I’d just buy the appropriate ropes and be confident that my boats not getting fkd up every time the wind blows.
