  • Publication number: 20100139541
    Abstract: A docking and cleaning device comprising a frame having scrubbers affixed thereto for cleaning a boat hull at a horizontal section, such as the waterline. The frame comprises a movable elongated member so that when the frame is in an “open” position, the elongated members provide an opening through which a boat may pass, entering into a docking area formed by the frame. The elongated member is moved so that the frame is in a “closed” position where the frame substantially conforms to the shape of the boat hull. Wave motion acting on the boat and the frame allow the scrubbers to frictionally contact and clean the boat hull at the waterline.
