A piece of tarred canvas nailed round above the partners, or that part where the mast or bowsprit enters the deck. Its use is to prevent the water from running down between decks. There is sometimes a coat for the rudder, nailed round the hole where the rudder traverses in the ship's counter. It also implies the stuff with which the ship's sides or masts are varnished, to defend them from the sun and weather, as turpentine, pitch, varnish, or paint; in this sense we say, "Give her a coat of tar or paint." By neglecting the scraper this may become a crust of coatings.
