ABSTRACT:
A bollard used in vessel mooring and like operations includes a bollard drum around which the line or hawser is wrapped several times to reduce the line tension at the free length behind the drum. A cleat is provided for holding fast the free length of the hawser at the reduced tension. The hawser may be quickly released from the bollard during emergency situations by simultaneously unlatching the cleat and releasing a lock on the bollard allowing it to rotate as the hawser is pulled off and finally lifted out of the cleat.
