Used, before the introduction of the truss, to attach a yard to the masts of a square-rigger, and it sometimes still is. The basic form uses a string of wooden parrel balls, sometime called bullseyes or trucks, to reduce chafe. With lighter yards a parrel rope, formed with an eye at each end and seized to the spar, is sometimes used. For heavier spars it was common to have loose ribs interposed between each parrel ball, which were called ribs of a parrel. Metal collars called parrel bands are also used. A parrel lashing is sometimes used at the lower parts of upper masts for extra security.
