ABSTRACT:
A boat mooring device designed to be used with a second similar mooring device to hold a boat away from a dock while allowing up and down movement of the boat in response to water level changes. In a preferred embodiment, each mooring device has an arm that extends out from the dock and is coupled to a base for movement about both a generally horizontal axis permitting lateral swinging of the arm, and a vertical axis permitting up and down movement of the arm. The two movements are cushioned by a tension spring that is connected between the base and the inner end of the arm so that the spring is tensioned whenever the arm moves down or swings laterally from a rest position.
