A range of large ropes, extended from the mast heads to the right and left sides of a ship, to support the masts, and enable them to carry sail. The shrouds, as well as the sails, etc, are denominated from the masts to which they belong; thus there are the main, fore, and mizzen shrouds; the main top-mast, fore top-mast, and mizzen top-mast shrouds; and the main top-gallant, fore top-gallant, and mizzen top-gallant shrouds. See Ship.
