Pacific Vortex: Where there's smoke, there's fire and more

Pg X

"We're nowhere near the northern shipping lanes."
The establishment of the North Atlantic sea lanes was inspired by the sinking of the US mail steamer Artic by collision with the French steamer 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 Saliling 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, 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.

Shipping lanes came to be by analysing the prevailing winds. It is well known that the trade winds allowed ships to sail towards the west quickly, and that 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.

It should be noted however, that the sea lanes were chosen based on the importance of cities as well, which could explain some anomalies towards the currents/winds, such as the fact that the shipping lanes are not optimally chosen for the route from Cape town towards Rio de Janeiro (passing Tristan da Cunha).

The Northern Sea Route is a shipping lane officially defined by Russian legislation from the Atlantic Ocean to the Pacific Ocean specifically running along the Russian Arctic coast from Murmansk on the Barents Sea, along Siberia, to the Bering Strait and Far East. The entire route lies in Arctic waters and parts are free of ice for only two months per year. Before the beginning of the 20th century it was known as the Northeast Passage, and is still sometimes referred to by that name.


"The San Francisco to Honolulu to Orient traffic is four hundred miles south."
Shipping routes reflect world trade flows. Sailings are most numerous and most frequent on routes where trade volumes are largest and demand is therefore greatest.

In liner trades to and from the UK, the busiest routes are to the Far East (especially China and Japan), passing through the Mediterranean, the Suez Canal and the Malacca Straits. The North Atlantic route, linking Western Europe and the USA and Canada, is also busy, and there are well-established routes to the Middle East, India, Australia and New Zealand, Central and South America, as well as to East and West Africa.

There are direct liner services from the UK to most other countries, and certainly to all the main trading economies. However, if your cargo is destined for a smaller port in one of these countries or for a port in a country with little trade with the UK, there may not be a direct sailing available - in which case, your cargo will need to be transhipped to another local sailing at the end of the ocean voyage.

In-bulk trade routes reflect the places of origin and consumption of the commodities carried. For example, many of the main oil routes begin in the Middle East and end in developed countries where demand for oil is greatest.

"Are you positive?"
"Stake my rating on it."

United States Navy ratings are general occupations that consist of specific skills and abilities. Each naval rating has its own specialty badge, which is worn on the left sleeve of the uniform by each enlisted person in that particular field. Working uniforms, such as camouflage Battle Dress Uniforms, utilities, coveralls, and Naval Working Uniform, bear generic rate designators that exclude the rating symbol. Just as an officer has rank, not a rate, an officer's occupation (if drawn more narrowly than an officer of the line) is classified according to designators and professional staff corps.

Ratings should not be confused with rates, which describe the Navy's enlisted pay-grades. Enlisted sailors are referred to by their rating and rate. For example, if someone's rate is Petty Officer 2nd Class and his rating is Boatswain's Mate, then combining the two—Boatswain's Mate 2nd Class (BM2)—defines both rate and rating in formal address or epistolary salutation.
