Abstract: A docking and mooring device for water borne vessels, such device being structured to automatically adjust for water level variations and conditions alongside the mooring location. The device comprises one or more vertically positioned structures on which are mounted pulley systems, with each vertically disposed pulley system encompassing a closed looped line; said closed loop line being indirectly tied to a portion of the moored boat. Such closed loop on each pulley system is vertically disposed and drawn over upper and lower disposed pulleys, so that such closed loop can be freely moved up and down with water level variations or changes in water conditions, and with the vessel being indirectly tied to said closed loop, the vessel itself will also move up and down with said conditions.
