ABSTRACT:
A device for measuring tension in a line for mooring a ship to a dock or an anchor. The device includes three pulleys secured to rigid frames or springs. Sensors are placed on rigid frames, springs or shafts for securing the pulleys. Portions of the mooring line extending from a center pulley to the other two pulleys are approximately perpendicular to portions of line extending from the two pulleys to a winch or a mooring post or hook. The springs between the pulleys may provide resilience in the mooring line which may obviate a need for a pendent line between the mooring line and the winch. The sensors communicate with a signal-processing unit which transmits amplified sensor signals to a monitor which is accessible to personnel aboard the ship. The monitor may display the tension in the mooring line in text or graphic formats.
