BUOY. A sort of close cask, or block of wood, fastened by a rope to the anchor, to show its situation after being cast, that the ship may not come so near it as to entangle her cable about its stock or flukes.—To buoy a cable is to make fast a spar, cask, or the like, to the bight of the cable, in order to prevent its galling or rubbing on the bottom. When a buoy floats on the water it is said to watch. When a vessel slips her cable she attaches a buoy to it in order afterwards to recover it. Thus the blockading squadrons off Brest and in Basque Roads frequently slipped, by signal, and each in beautiful order returned and picked up their cables.—To stream the buoy is to let it fall from the ship's side into the water, which is always done before the anchor is let go, that it may not be fouled by the buoy-rope as it sinks to the bottom.—Buoys of various kinds are also placed upon rocks or sand-banks to direct mariners where to avoid danger.
BUOYANCY. Capacity for floating lightly.—Centre of buoyancy, in naval architecture, the mean centre of that part of the vessel which is immersed in the water. (See [Centre of Cavity].)
BUOYANT. The property of floating lightly on the water.
BUOY-ROPE. The rope which attaches the buoy to the anchor, which should always be of sufficient strength to lift the anchor should the cable part; it should also be little more in length than equal to the depth of the water (at high-water) where the anchor lies.—To bend the buoy-rope, pass the running eye over one fluke, take a hitch over the other arm, and seize. Or, take a clove-hitch over the crown on each arm or fluke, stopping the end to its own part, or to the shank.
BUOY-ROPE KNOT. Used where the end is lashed to the shank. A knot made by unlaying the strands of a cable-laid rope, and also the small strand of each large strand; and after single and double walling them, as for a stopper-knot, worm the divisions, and round the rope.
BURBOT. A fresh-water fish (Molva lota) in esteem with fishermen.
BURDEN. Is the quantity of contents or number of tons weight of goods or munitions which a ship will carry, when loaded to a proper sea-trim: and this is ascertained by certain fixed rules of measurement. The precise burden or burthen is about twice the tonnage, but then a vessel would be deemed deeply laden.
BURG [the Anglo-Saxon burh]. A word connected with fortification in German, as in almost all the Teutonic languages of Europe. In Arabic the same term, with the alteration of a letter, burj, signifies primarily a bastion, and by extension any fortified place on a rising ground. This meaning has been retained by all northern nations who have borrowed the word; and we, with the rest, name our towns, once fortified, burghs or boroughs.
BURGALL. A fish of the American coasts, from 6 to 12 inches long: it is also called the blue-perch, the chogset, and the nibbler—the last from its habit of nibbling off the bait thrown for other fishes.
BURGEE. A swallow-tailed or tapered broad pendant; in the merchant service it generally has the ship's name on it.
