  • Patent number: 4656961
    Abstract: Disclosed is a mooring device for mooring a vessel to a mooring object, whether fixed or floating; e.g., a dock, dolphin, another vessel, etc. The device comprises an elongated beam from which a pair of arms, offset lengthwise of the beam, project in opposite directions to remote or distal ends. The arms normally occupy positions standing straight out from the beam while the distal ends of the arms are tied respectively to the vessel and to the mooring object. The arms are biased to the stand-out positions but may yield as the vessel moves because of active water, wind and the like. The biasing elements are preferably nylon-covered shock cord.
