How Much Does a Boat Dock Cost?

While docks have many purposes, the main purpose of a dock is to restrain a boat while allowing passengers to get on and off the boat.    Rather than having to visit a boat launch to put in and take out your boat each time you use it, many, who have legal access to the water, can install their own dock to keep the boat in the water at all times.
