Although there are other important factors, the main cause of losing anchors and chain cable during anchoring, particularly in large ships, is too high a cable speed. The article discusses the rapid decrease in the coefficient of friction between the braking surfaces of a windlass as the temperature of these surfaces rises, and recommends that cable speed should be kept constant at about 1 metre per second and should not, in any event, exceed 2 m/sec. Cable speed is more easily controlled with a hydraulically-operated brake than with the manually-operated type. The article includes numerical and other data to demonstrate the advantages of adequate control of cable speed, together with a description of a hydraulic automatic speed-control system.
