Abstract: The dock includes a pair of substantially vertical support members having a vertically adjustable collar mounted on each. The deck portion of the dock has one end attached to the pair of adjustable collars and the other end supported through at least one pair of cables, each attached proximate the free end of the deck member and passing over a V-way at the top of the respective vertical support member with its other end finally anchored to the ground inland of the shoreline. The dock is thus vertically adjustable by means of the cables and collars to accommodate to the height of the changing levels of water. It is furthermore pivotable upwardly from the water surface to avoid damage such as might result in periods of high water or winter ice formation along the shoreline.
