An eyelet in the edge of a sail, usually a small one such as is used +to attach a luff-slide. Modern sails have grommets at head, tack and clew, but habit has endowed those larger grommets with the name of Cringle. In the past that word was reserved for a ring attached outside the bolt rope, whereas a grom¬met was an eye within the rope, in the margin ofthe cloth itself. The brass eyelets you can fit yourself with a punch and die are grommets aboard ship.
