Anti-Tordsion Line is used in headsail and top down spinnaker furlers. The furling is controlled by the furler drum at the bottom of the sail. The turing force is transmitted
through the length of the ProDrive cable to turn the swivel which is connected to the head of the sail. The tack of the sail is connected
to a freely floating point on the drum of the furling unit. The turning force acting at the top of the sail only, causes the head of the
sail to furl first and ensures the sail furls down the cable neatly.
