A pair of fenders are mounted vertically on a rectangular shaped plate which has a pair of legs connected in rotational engagement to the gravity base. The fenders function to transmit a moored vessels load to the gravity base. Activating an air operated cylinder mounted within the gravity base will effectuate the movement of the plates support structure so as to cause the plate to rise from a first position which is parallel to and above the gravity base to a second position which is perpendicular to and above the gravity base. Six propellant embedment anchors hold the dolphin in place. Keywords Patents Dolphins structures Portable equipment Ship moorings. EDC
