A short piece of rope worked grommet fashion into the bolt-rope of a sail and containing a metal thimble. In the days of sail they were used to hook in the tack and sheet tackles when they had to be moved up when a sail was reefed. In the days of square-rigged ships, cringles were used on the sails for extending the leech of the sail by means of bowline bridles for extra driving power in a head wind. The word is derived from the Old English crencled, meaning circle, or circularly formed.
