Never seen one on a dock but looks pretty self explanatory to me

If it stays on the dock, why not make it a dock mountable fender? that way your regular fenders are put away and you dont have to mess with putting them away and getting them out whenever you used the boat??

I just dont get the whole concept these days of making time saving/.step saving products that add more time and steps

Lots of marinas frown on screwing things to the dock.

That`s a great idea! wont flop around like a limp dick in the wind.

So when you leave you can take it with you instead of buying twice the fenders.

Yeah you can buy a fender holder that probably costs as much as a fender.... lol

I don't get it . The holder sticks out from the dock for your boat to bounce against . What you spend on holders could pay for some permanent mounted bumpers.
