ABSTRACT:
A device for maintaining docks or other floating bodies at a given distance from and orientation to the shore by means of a ratchet assembly hinged on the side of the dock closest to shore, and a line attached to two guides, such as pulleys, on the underside of the dock. When the level of the water varies, the device maintains the dock at the same distance from the new waterline as it was from the old, in the following manner: the line is anchored at one end on shore and at the other to a bottom anchor beyond the farthest point the dock will extend to at lowest water level. Tension in the line pushes the dock towards the shore until the ratchet contacts the bottom, where equilibrium is established. If the water falls, the ratchet pushes the dock away from shore and a new equilibrium is established, farther out; this repeats as long as the water falls. If the level rises, the ratchet is raised off the bottom and the dock moves towards shore to a new equilibrium point. This continues as long as the water rises. Guides are configured so as to minimize rotational movement.
