Buoys  

Definition

  • A floating object anchored at a definite location to guide or warn mariners, to mark positions of submerged objects, or to moor vessels in lieu of anchoring. Two international buoyage systems are used to mark channels and submerged dangers. In both systems, buoys of standardized colours and shapes indicate safe passageways. Special-purpose buoys are designed for a variety of uses; they include cable buoys, anchor buoys, or race buoys. A mooring buoy differs from other types in not being an aid to navigation but a point to which vessels may be tied up. Secured to a permanent group of anchors by a heavy chain, such a buoy serves as a connecting link between the vessel and the anchors. The use of mooring buoys conserves space in crowded harbours because a moored vessel requires less room to swing with the wind and tide than does a vessel at anchor. (en)
