  • Patent number: 6575110
    Abstract: The invention is a guide to facilitate boat docking. The guide is a plate attached to the dock, angling away from the slip opening. Attached to the plate are rails which absorb energy and minimize friction when contact occurs while docking. Structural members attached to the plate allow its attachment to the dock, and support the plate against bending when boats contact the rails. Guides are typically attached to docks on each side of the slip, to facilitate docking with minimal effort, providing a wide opening which narrows as the boat enters the slip, directing the boat into the slip.
