Sailing Directions
General information Sailing Directions are volumes published by various National Hydrographic Offices or Coast Guard Agencies which provide essential information to support port entry and coastal navigation for all classes of ships at sea. Sailing directions are part of the carriage requirements defined by the SOLAS Convention. Content Sailing Directions contain information on countries, navigational hazards, buoyage, pilotage, regulations, anchorages and port facilities, seasonal currents, ice and climatic conditions. Diagrams and photos are included to help identifying places through textual description during coastal navigation and to support the passage planning stage. This information, when used alongside official navigational charts, will provide context and can help to increase the situational awareness of the bridge team. Sailing directions, also known as Pilots, provide the local knowledge and awareness which would typically be provided by a local marine pilot. Hi ...

SOLAS Convention
The International Convention for the Safety of Life at Sea (SOLAS) is an international maritime treaty which sets out minimum safety standards in the construction, equipment and operation of merchant ships. The International Maritime Organization convention requires signatory flag states to ensure that ships flagged by them comply with at least these standards. Initially prompted by the sinking of the Titanic, the current version of SOLAS is the 1974 version, known as SOLAS 1974, which came into force on 25 May 1980, and has been amended several times. , SOLAS 1974 has 167 contracting states, which flag about 99% of merchant ships around the world in terms of gross tonnage. SOLAS in its successive forms is generally regarded as the most important of all international treaties concerning the safety of merchant ships. Signatories The non-parties to SOLAS 1974 include numerous landlocked countries, as well as El Salvador, Micronesia and East Timor. Some others including Bolivi ...

Sailing Books
Sailing employs the wind—acting on sails, wingsails or kites—to propel a craft on the surface of the ''water'' (sailing ship, sailboat, raft, windsurfer, or kitesurfer), on ''ice'' (iceboat) or on ''land'' ( land yacht) over a chosen course, which is often part of a larger plan of navigation. From prehistory until the second half of the 19th century, sailing craft were the primary means of maritime trade and transportation; exploration across the seas and oceans was reliant on sail for anything other than the shortest distances. Naval power in this period used sail to varying degrees depending on the current technology, culminating in the gun-armed sailing warships of the Age of Sail. Sail was slowly replaced by steam as the method of propulsion for ships over the latter part of the 19th century – seeing a gradual improvement in the technology of steam through a number of developmental steps. Steam allowed scheduled services that ran at higher average speeds than saili ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Hydrography
Hydrography is the branch of applied sciences which deals with the measurement and description of the physical features of oceans, seas, coastal areas, lakes and rivers, as well as with the prediction of their change over time, for the primary purpose of safety of navigation and in support of all other marine activities, including economic development, security and defense, scientific research, and environmental protection. History The origins of hydrography lay in the making of charts to aid navigation, by individual mariners as they navigated into new waters. These were usually the private property, even closely held secrets, of individuals who used them for commercial or military advantage. As transoceanic trade and exploration increased, hydrographic surveys started to be carried out as an exercise in their own right, and the commissioning of surveys was increasingly done by governments and special hydrographic offices. National organizations, particularly navies, realize ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Marine Navigation
Marine navigation is the art and science of steering a ship from a starting point (sailing) to a destination, efficiently and responsibly. It is an art because of the skill that the navigator must have to avoid the dangers of navigation, and it is a science because it is based on physics, physical, mathematical, oceanographic, cartographic, astronomical, and other knowledge. Marine navigation can be surface or Submarine navigation, submarine. Etymology Navigation (from the Latin word ''navigatio'') is the act of sailing or voyaging. Nautical (from Latin ''nautĭca'', and this from Greek language, Greek ναυτική [τέχνη] ''nautikḗ [téjne]'' "[art of] sailing" and from ναύτης ''nautes'' "sailor") is that pertaining to navigation and the science and art of sailing. Naval (from the Latin adjective ''navalis'') is that relating to ships and navigation, or particularly to the navy. In Ancient Rome, the ''navicularii'' conducted long-distance trade by sea.

Nathaniel Bowditch
Nathaniel Bowditch (March 26, 1773 – March 16, 1838) was an early American mathematician remembered for his work on ocean navigation. He is often credited as the founder of modern maritime navigation; his book '' The New American Practical Navigator'', first published in 1802, is still carried on board every commissioned U.S. Naval vessel. Life and work Nathaniel Bowditch, the fourth of seven children, was born in Salem, Province of Massachusetts Bay, to Habakkuk Bowditch, a cooper who at one point was a sailor as well but stopped after his ship went aground in 1775, and Mary Ingersoll Bowditch. At the age of ten, he was made to leave school to work in his father's cooperage, before becoming indentured at twelve for nine years as a bookkeeping apprentice to a ship chandler. Here is where he first learned bookkeeping, an important step in his life. In 1786, age fourteen, Bowditch began to study algebra and two years later he taught himself calculus. He also taught himsel ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Buoy
A buoy (; ) is a buoyancy, floating device that can have many purposes. It can be anchored (stationary) or allowed to drift with ocean currents. History The ultimate origin of buoys is unknown, but by 1295 a seaman's manual referred to navigation buoys in the Guadalquivir River in Spain. To the north there are early medieval mentions of the French / Belgian River Meuse, Maas being buoyed. Such early buoys were probably just timber beams or rafts, but in 1358 there is a record of a barrel buoy in the Dutch Maasmond (also known as the Maas Sluis or Maasgat). The simple barrel was difficult to secure to the seabed, and so a conical ''tonne'' was developed. They had a solid plug at the narrow end through which a mooring ring could be attached. By 1790 the older conical tonne was being replaced by a ''nun'' buoy. This had the same conical section below the waterline as the tonne buoy, but at the waterline a barrel shape was used to allow a truncated cone to be above the water. ...
