BUOR-Rope, the rope which fastens the buoy to the anchor: it should be little more than equal in length to the depth of the water where the anchor lies, as it is intended to float near, or immediately above, the bed of it, that the pilot may at all times know the situation thereof. See Plate XXXIII. Fig. 1. No 3. where b is the anchor, c the buoy-rope, and d the buoy floating on the surface of the water. The buoy-rope is often extremely useful otherwise, in drawing up the anchor when the cable is broke. It should always, therefore, be of sufficient strength for this purpose, or else the anchor may be lost through negligence.
BUOR of the Nore, is a buoy placed at the mouth of the river Thames, to direct mariners how to avoid a dangerous sand.
