I stumbled on a video describing a product called Dock Styx. It holds your boat at a dock without touching the dock. Looked very clever, so I went to YouTube and typed in Dock Sticks and up pops loads of videos for making it at a fraction of the cost. I made a visit to my Ace Hardware for parts (under $20) and 15 minutes in the shop to assemble. I thought I would share.
