Морской переулок

Морской путь , морская дорога или судоходный путь — это регулярно используемый судоходный маршрут для больших водных судов ( судов ) на широких водных путях, таких как океаны и большие озера , и предпочтительно является безопасным, прямым и экономичным. В эпоху парусного спорта они определялись распределением суши , а также преобладающими ветрами , открытие которых имело решающее значение для успеха длительных морских путешествий. Морские пути очень важны для морской торговли.

История

The establishment of the North Atlantic sea lanes was inspired by the sinking of the US mail steamer SS Arctic by collision with the French steamer SS Vesta in October 1854 which resulted in the loss of over 300 lives. Lieutenant M. F. Maury of the US Navy first published a section titled "Steam Lanes Across the Atlantic" in his 1855 Sailing Directions proposing sea lanes along the 42 degree latitude. A number of international conferences and committees were held in 1866, 1872, 1887, 1889, and 1891 all of which left the designation of sea lanes to the principal trans-Atlantic steamship companies at the time; Cunard, White Star, Inman, National Line, and Guion Lines. In 1913–1914 the International Convention for Safety of Life at Sea held in London again reaffirmed that the selection of routes across the Atlantic in both directions is left to the responsibility of the steamship companies.^[1]

Shipping lanes came to be by analysing the prevailing winds. The trade winds allowed ships to sail towards the west quickly, and the westerlies allowed ships to travel to the east quickly. As such, the sea lanes are mostly chosen to take full advantage of these winds. Currents are also similarly followed as well, which also gives an advantage to the vessel.^{[citation needed]} Some routes, such as that from Cape Town to Rio de Janeiro (passing Tristan da Cunha), were not able to take advantage of these natural factors.

Main sea lanes may also attract pirates.^{[citation needed]} Pax Britannica was the period from 1815–1914 during which the British Royal Navy controlled most of the key maritime trade routes, and also suppressed piracy and the slave trade. During World War I, as German U-boats began hitting American and British shipping, the Allied trade vessels began to move out of the usual sea lanes to be escorted by naval ships.

Advantages

Although most ships no longer use sails (having switched them for engines), the wind still creates waves, and this can cause heeling. As such following the overall direction of the trade winds and westerlies is still very useful. However, it is best for any vessel that is not engaged in trading, or is smaller than a certain length, to avoid the lanes. This is not only because the slight chance of a collision with a large ship that can easily cause a smaller ship to sink, but also because large vessels are much less maneuverable than smaller ships, and need much more depth. Smaller ships can thus easily take courses that are nearer to the shore. Unlike with road traffic, there is no exact "road" a ship must follow, so this can easily be done.

Shipping lanes are the busiest parts of the sea, thus being a useful place for stranded boaters whose boats are sinking or people on a liferaft to boat to, and be rescued by a passing ship.

Threats from shipping lanes

Shipping lanes may pose threats to some ocean-going craft. Small boats risk conflicts with bigger ships if they follow the shipping lanes. Sections of lanes exist which can be shallow or have some kind of obstruction (such as sand banks). This threat is greatest when passing some narrows, such as between islands in the Indian Ocean (e.g. in Indonesia) as well as between islands in the Pacific (e.g. near the Marquesas islands, Tahiti). Some shipping lanes, such as the Straits of Malacca off Indonesia and Malaysia, and the waters off Somalia, are frequented by pirates operating independently or as privateers (for companies and countries). Passing ships run the risk of being attacked and held for ransom.

Busiest shipping lanes

Самый загруженный судоходный путь в мире — Дуврский пролив . 500–600 судов в день пересекают узкий пролив, а в 1999 году через пролив прошло 1,4 миллиарда тонн брутто, перевезенных 62 500 судами. ^{[ 2 ]}
