Buoy
1911 Encyclopedia Britannica
or (15th century "boye"; through O. Fr. or Dutch, from Lat. boia, fetter; the word is now usually pronounced as "boy," and it has been spelt in that form; but Hakluyt's Voyages spells it "bwoy," and this seems to indicate a different pronunciation, which is also given in some modern dictionaries), a floating body employed to mark the navigable limits of channels, their fairways, sunken dangers or isolated rocks, mined or torpedo grounds, telegraph cables, or the position of a ship's anchor after letting go; buoys are also used for securing a ship to instead of anchoring. They vary in size and construction from a log of wood to steel mooring buoys for battleships or a steel gas buoy.
In 1882 a conference was held upon a proposal to establish a uniform system of buoyage. It was under the presidency of the then duke of Edinburgh, and consisted of representatives from the various bodies interested. The questions of colour, visibility, shape and size were considered, and any modifications necessary owing to locality. The committee proposed the following uniform system of buoyage, and it is now adopted by the general lighthouse authorities of the United Kingdom: (1) The mariner when approaching the coast must determine FIG. I. FIG. 2. FIG. 3.
his position on the chart, and note the direction of) flood tide.
(2) The term "starboard-hand" shall denote that side which would be on the right hand of the mariner either going with the main stream of the flood, or entering a harbour, river or estuary from seaward; the term "port-hand" shall denote the left hand of the mariner in the same circumstances. (3) 1 Buoys showing the pointed top of a cone above water shall be called conical (fig. 1) and shall always be starboard-hand buoys, as above defined. (4) 1 Buoys showing a flat top above water shall be called can (fig. 2) and shall always be port-hand buoys, as above defined. (5) Buoys showing a domed top above water shall be called spherical (fig. 3) and shall mark the ends of middle grounds. (6) Buoys having a tall central structure on FIG. 4. FIG. 5. FIG. 6 a broad face shall be called pillar buoys (fig. 4), and like all other special buoys, such as bell buoys, gas buoys, and;automatic sounding buoys, shall be placed to mark special positions either on the coast or in the approaches to harbours.:: (7) Buoys showing only a mast above water shall be called spar-buoys2 (fig. 5). (8) Starboard-hand buoys shall always 'be painted in one colour only. (9) Port-hand buoys shall be, 'painted of another characteristic colour, either single or parti-colour. (to) Spherical buoys (fig. 3) at the ends of middle grounds shall always be distinguished by horizontal stripes of white colour. (11) Surmounting beacons, such as staff and globe and others, 3 shall always be painted of one dark colour. (12) Staff and globe (fig. 1) shall only be used on starboard-hand 1 In carrying out the above system the Northern Lights Commissioners have adopted a red colour for conical or starboard-hand buoys, and black colour for can or port-hand buoys, and this system is applicable to the whole of Scotland.
2 Useful where floating ice is encountered.
3 St George and St Andrew crosses 'are principally employed to surmount shore beacons.
buoys, staff and cage (fig. 2) on port hand; diamonds (fig. 7) at the outer ends of middle grounds; and triangles (fig. 3) at the inner ends. (13) Buoys on the same side of a channel, estuary or tideway may be distinguished from each other by names, numbers or letters, and where necessary by a staff surmounted with the appropriate beacon. (14) Buoys intended for moorings (fig. 6) may be of shape and colour according to the discretion of the authority within whose jurisdiction they are laid, but for marking submarine telegraph cables the colour shall be green with the word "Tele graph" painted thereon in white letters.
Buoying and Marking of Wrecks
(15) Wreck buoys in the open sea, or in the approaches to a harbour or estuary, shall be coloured FIG green, with the word "Wreck" painted in white 7 letters on them. (16) When possible, the buoy should be laid near to the side of the wreck next to mid-channel. (17) When a wreck-marking vessel is used, it shall, if possible, have its top sides coloured green, with the word "Wreck" in white letters thereon, and shall exhibit by day, three balls on a yard 20 ft. above the sea, two placed vertically at one end and one at the other, the single ball being on the side nearer to the wreck; in fog a gong or bell is rung in quick succession at intervals not exceeding one minute (wherever practicable); by night, three white fixed lights are similarly arranged as the balls in daytime, but the ordinary riding lights are not shown. (18) In narrow waters or in rivers and harbours under the jurisdiction of local authorities, the same rules may be adopted, or at discretion, varied as follows: - When a wreck-marking vessel is used she shall carry a cross-yard on a mast with two balls by day, placed horizontally not less than 6 nor more than 12 ft. apart, and by night two lights similarly placed. 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.
British India has practically adopted the British system, United States and Canada have the same uniform system; in the majority of European maritime countries and China various uniform systems have been` adopted. In Norway and Russia the compass system is used, the shape, colour and surmount ings of the buoys indicating the compass bearing of the danger =?l from the buoy; this method is followed in the open sea by Sweden. An international uni form system of buoyage, although /1 desirable, appears impracticable.
Germany employs yellow buoys to mark boundaries of quaran- 5-!Wt., tine stations. The question of Chequered shape versus colour, irrespective of size, is a disputed one; the shape FIG. IO.
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; the varying backgrounds and atmospheric conditions render the question a complex one.
