BARRICADE, in Naval Architecture, a strong wooden rail, supported by flanchions, extending across the foremost part of the quarter-deck. In a vessel of war, the vacant spaces between the flanchions are commonly filled with rope-matts, cork, or pieces of old cable; and the upper part, which contains a double ropenetting above the rail, is stuffed with full hammocks to intercept the motion, and prevent the execution of small-shot in the time of battle.
