John Whitly Dixon, 1911 Encyclopædia Britannica (1911)

“ In Norway and Russia the compass system is used, the shape, colour and surmountings of the buoys indicating the compass bearing of the danger from the buoy; this method is followed in the open sea by Sweden. An international uniform system of buoyage, although desirable, appears impracticable. Germany employs yellow buoys to mark boundaries of quarantine stations. The question of shape versus colour, irrespective of size, is a disputed one; the shape is a better guide at night and colour in the daytime. All markings (figs. 8, 9, 10 and 11) should be subordinate to the main colour of the buoy ”

“ Automatic buoys cannot be relied on in calm days with a smooth sea. The nun buoy (fig. 14) for indicating the position of an anchor after letting go, is secured to the crown of the anchor by a buoy rope. It is usually made of galvanized iron, and consists of two cones joined together at the base. It is painted red for the port anchor and green for the starboard.
Mooring buoys (fig. 6) for battleships are built of steel in four watertight compartments, and have sufficient buoyancy to keep afloat should a compartment be pierced; they are 13 ft. ”

“ In 1898 steel studs were introduced instead of cast iron ones, the latter having a tendency to work loose, but the practice is not universal. After testing, the licensed tester must place on every five fathoms of cable a distinctive mark which also indicates the testing establishments; the stamp or die employed must be approved by the Board of Trade. ”

“ When a barge or open boat only is used, a flag or ball may be shown in the daytime. (19) The position in which the marking vessel is placed with reference to the wreck shall be at the discretion of the local authority having jurisdiction. A uniform system by shape has been adopted by the Mersey Dock and Harbour Board, to assist a mariner by night, and, in addition, where practicable, a uniform colour; the fairway buoys are specially marked by letter, shape and colour. ”

“ For instance, if the wire is on the sixth studs on each side of the shackle, it indicates that six lengths or 75 fathoms of cable are out. In joining the lengths together, the round end of the shackle is placed towards the anchor. The end links of each length (C.C.) are made without studs, in order to take the shackle; but as studs increase the strength of a link, in a studless or open link the iron is of greater diameter. ”

“ The buoy holds 380 cub. ft. of gas, and exhibits an occulting light for 2533 hours. This light is placed 10 ft. above the sea, and, with an intensity of 50 candles, is visible 8 m. It occults every ten seconds, and there is seven seconds’ visibility, with three seconds’ obscuration. The occultations are actuated by a double valve arrangement. In the body of the apparatus there is a gas chamber having sufficient capacity, in the case of an occulting light, for maintaining the flame in action for seven seconds, and by means of a by-pass a jet remains alight in the centre of the burner. ”

“ The sizes, number and lengths of cables supplied to ships of the British navy are given in the official publication, the Ship’s Establishment; cables for merchant ships are regulated by Lloyds, and are tested according to the Anchors and Chain Cables Act 1899. ”
