Abstract: A marine docking device according to the present invention includes a fender having a first end coupled to a first arm by a first attachment member and a second end coupled to a second arm by a second attachment member. The first attachment member and the second attachment member are configured to prevent the fender from rotating about a longitudinal axis that passes through the first end and the second end. The first arm includes a compression assembly that facilitates movement of the first end between a first position and a second position. The compression assembly includes a tubular member that is slidable within a sleeve. A spring is compressed between a first spring abutment provided on the sleeve and a second spring abutment provided on the tubular member. The first spring abutment is continuously urged toward an advanced position by the spring.
