A heavy tackle with double or treble blocks with the upper blocks at the head of the lower masts of square-rigged ships. Used for lifting or lowering the course and its yard. The fall is usually taken to a capstan between the masts or to a power winch. Some modern ships do not fit jeers and rely on the lifts, or on dockyard cranes, for this operation. The jeer capstan was often the scene for punishments in early sailing ships.
