Hoops or rings of rope, wood, or iron, fixed upon the stays, to seize the luff of fore-and-aft sails, and to confine the staysails thereto, at different distances. Those of wood are used in lieu of grommets, being much more convenient, and of a later invention. They are framed by the bending of a rough piece of wood into the form of a wreath, and fastened at the two ends by means of notches, thereby retaining their circular figure and elasticity; whereas the grommets which are formed of rope are apt to relax in warm weather, and adhere to the stays, so as to prevent the sails from being readily hoisted or lowered.
