TOPIC: Working on dock.

I am working on the dock at my new house. It is a strange dock. It is anchored into the hillside but is floating. It has 2 sets of hinges one at the Whiteside where it meets the gangway and one at the dock side. My neighbors is similar. Has anyone seen one like this?
I am looking for Ideas and what size cleats I should get. I am also interested in an inexpensive boat lift or drydock. My boat is 15ft runabout.
I am located on Lake Brownwood in Texas about 50 mile SE. of Abilene.

Maybe all that metal framework is for stability perhaps?

Does any thing in Texas not get built from well casing ?

As to rthe well casings I don't think so!
I am farther along but unfortunately I had my boat ties up to the dock during a thunderstorm and the rub rail on the dock removed the rubrail from my boat and visa versa.
The boat had its mounting for the rub rail broken off along the side and the rubber torn off. Th boat rides with the aft end below the facia on the dock and the bow slightly above. Now I need to some how repair the rub rail. What is the company's name that still makes the rub rails?
