BOAT DOCK MOORING DEVICE A mooring arm structure is provided including a first elongated arm mounted at one end for angular displacement relative to a dock supported mount about a horizontal axis extending transversely of the first arm and with the second free end of the first arm projecting outwardly beyond one marginal portion of the dock. The second end of the first arm has the upper end of a depending second arm anchored relative thereto and the second arm is constructed of shape retentive resilient material. The lower end of the second arm has a ball hitch socket assembly supported therefrom and an air-place-type shock absorber is connected between the lower end of the second arm and a longitudinal midportion of the first arm. In a modified form, the mount is supported from the dock marginal portion for vertical guided shifting therealong and motor structure is operatively connected thereto for raising and lowering the mount responsive to excessive raising and lowering, respectively, of the second end of the first arm.
