buoy

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.
