International Association Of Marine Aids To Navigation And Lighthouse Authorities
The International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA), previously known as International Association of Lighthouse Authorities, is an intergovernmental organization founded in 1957 to collect and provide nautical expertise and advice. IALA is also known by its French name of ''Association Internationale de Signalisation Maritime'' (AISM). Background IALA brings together representatives of the aids to navigation services of about 80 countries for technical coordination, information sharing, and coordination of improvements to aids to navigation throughout the world. It was established in 1957 to provide a permanent organization to support the goals of the Technical Lighthouse Conferences, which had been convening since 1929. The General Assembly of IALA meets about every four years. The council of 24 members meets twice a year to oversee the ongoing programs. Four committees maintain work programs established for four year periods: * ENAV&nbs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lighthouse Organizations
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
E-Navigation Concept
e-Navigation is a strategy developed by the International Maritime Organization (IMO), a UN specialized agency, to bring about increased safety of navigation in commercial shipping through better organization of data on ships and on shore, and better data exchange and communication between ships and the ship and shore. The concept was launched when maritime authorities from seven nations requested the IMO's Maritime Safety Committee to add the development of an e-navigation strategy to the work programs of the IMO's NAV and COMSAR sub-committees. Working groups in three sub-committees (NAV, COMSAR and STW) and an intersessional correspondence group, led by Norway, has subsequently developed a Strategy Implementation Plan (SIP). Member states of IMO and a number of Intergovernmental and non-governmental organisations have contributed to the work, including the International Hydrographic Organization (IHO), Comité International Radio-Maritime (CIRM), the International Association ...

General Lighthouse Authority
A general lighthouse authority (GLA) is one of three agencies primarily responsible for aids to navigation in the United Kingdom and the Republic of Ireland. They are divided into regions as follows: *Trinity House: England & Wales, Channel Islands and Gibraltar *Northern Lighthouse Board: Scotland and the Isle of Man *Commissioners of Irish Lights (the C.I.L.): the whole of Ireland A local lighthouse authority (LLA) is a port, harbour, or other party providing navigational aids in a locality as part of its facilities. These local authorities subscribe to the general lighthouse authority's policy on the correct maintenance and provision of such equipment. Funding for the three GLAs is primarily collected through light dues, which are pooled in the General Lighthouse Fund and dispersed to the three authorities. The Irish Government also makes a contribution to the GLF. The powers of Trinity House and the Northern Lighthouse Board are established in the Merchant Shipping Act 1995. ...

John Bury (captain)
Captain John Bury (28 July 1915 – 17 October 2006) was a master mariner and Elder Brother of Trinity House. He was involved in the adoption of a standardised buoyage system internationally. Bury was born in Moose Jaw, Saskatchewan. His parents were Welsh immigrants who had taken up farming on the Canadian prairie, but later returned to Wales. Bury took up a maritime career in 1931, becoming an apprentice on the Anchor Line. He joined the New Zealand Shipping Company in 1940 and served in the Merchant navy in World War II. He was promoted within the company to command its ships, before being elected to Trinity House. Mutually inconsistent buoyage systems had proliferated in the 19th and early 20th centuries, leading to many accidents at sea. As chairman of the IALA Buoyage Committee, Bury oversaw the introduction in the 1970s of a standardised maritime buoyage systems, involving cardinal marks painted yellow and black with topmarks and lights to indicate to mariners the d ...

American Practical Navigator
''The American Practical Navigator'' (colloquially often referred to as ''Bowditch''), originally written by Nathaniel Bowditch, is an encyclopedia of navigation. It serves as a valuable handbook on oceanography and meteorology, and contains useful tables and a maritime glossary. In 1867 the copyright and plates were bought by the Hydrographic Office of the United States Navy. As of 2019 it is still published by the U.S. Government and is available free online from the National Geospatial-Intelligence Agency (NGA), the modern successor agency to the 19th Century Hydrographic Office. The publication is considered one of America's nautical institutions. History The most popular navigational text of the late 18th century was ''The Practical Navigator'' by John Hamilton Moore of the Royal Navy, first published in 1772. To have exact tables to work from, Bowditch recomputed all of Moore's tables, and rearranged and expanded the work. He contacted the US publisher of the work, Edmun ...

Characteristic Light
A light characteristic is all of the properties that make a particular navigational light identifiable. Graphical and textual descriptions of navigational light sequences and colours are displayed on nautical charts and in Light Lists with the chart symbol for a lighthouse, lightvessel, buoy or sea mark with a light on it. Different lights use different colours, frequencies and light patterns, so mariners can identify which light they are seeing. Abbreviations While light characteristics can be described in prose, e.g. "Flashing white every three seconds", lists of lights and navigation chart annotations use abbreviations. The abbreviation notation is slightly different from one light list to another, with dots added or removed, but it usually follows a pattern similar to the following (see the chart to the right for examples). * An abbreviation of the type of light, e.g. "Fl." for flashing, "F." for fixed. * The color of the light, e.g. "W" for white, "G" for green, "R" for red, " ...

Isolated Danger Mark
An Isolated Danger Mark, as defined by the International Association of Lighthouse Authorities, is a sea mark used in maritime pilotage to indicate a hazard to shipping such as a partially submerged rock. It is recognisable by its black and red bands and top-mark of two black balls. Its distinctive sequence of flashing white light consists of 2 quick flashes in intervals of either 5 or 10 seconds. See also * Navigation * Lateral mark * Cardinal mark * Safe water mark * Special mark * Emergency wreck buoy An Emergency wreck buoy is used to warn of a new wreck which has not yet been listed in maritime documents. The buoy is expected to be deployed for the first 24-72 hours after the wreck occurs. After that time more permanent buoyage (such as ...

Special Mark
A Special Mark, as defined by the International Association of Lighthouse Authorities, is a sea mark used in maritime pilotage. It is recognisable by its yellow colour and X, (also referred to as a St. Andrews Cross or saltire) top-mark. It has a distinctive sequence of various flashes that does not match any other navigational mark flashes in its vicinity. Purpose Special marks can indicate: * Administrative areas * Water skiing areas * Anchorage areas * Mooring areas *Waiting areas *Marine farms *Oil wells * Dead ends * Pipelines *Spoil ground (an area where dredged material is deposited) *Historic wrecks *Protected areas * Outfall pipes (such as Stormwater, and Cooling water) * Sewerage pipes * Intake pipes *Submarine cables Other uses *Buoys, such as a Weather buoy or Mooring buoy are coloured yellow or have a yellow light to indicate it is not an aid to navigation.

Safe Water Mark
Examples of Safe Water Marks A safe water mark, as defined by the International Association of Lighthouse Authorities, is a sea mark used in maritime pilotage to indicate the end of a channel. They usually imply that open, deep and safe water lies ahead. They are also used to indicate the start and end of a buoyed section of a continuous narrow channel; and a series of them may mark a safe route through shallow areas. It is therefore important to consult appropriate charts to determine their meaning in each location. They are also known as fairway buoys and clear water buoys. They are recognisable by their red-and-white vertical stripes, and commonly bear a top sign in shape of a red ball. They either flash Morse code "A" (di-dah), or one long flash, occulting (more light than dark) or isophase (equal light and dark) every 10 seconds (L Fl 10s).Haire, Penny.''Yachtmaster''. Royal Yachting Association, 2009, p. 61. In the United States, safe water marks are printed with the ini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
