What Is the Meaning of the Word Circumnavigate

Navigation of a circumference

The Magellan-Elcano expedition was the first recorded circumnavigation of the Earth.

Circumnavigation is the complete navigation around an entire island, continent, or astronomical body (e.g. a planet or moon). This article focuses on the circumnavigation of Earth.

The first recorded circumnavigation of the Earth was the Magellan-Elcano expedition, which sailed from Seville, Spain in 1519 and returned in 1522, after crossing the Atlantic, Pacific, and Indian oceans. Since the rise of commercial aviation in the late 20th century, circumnavigating Earth is straightforward, usually taking days instead of years.[1] Today, the challenge of circumnavigating Earth has shifted towards human and technological endurance, speed, and less conventional methods.

Etymology [edit]

The word circumnavigation is a noun formed from the verb circumnavigate, from the past participle of the Latin verb circumnavigare, from circum "around" + navigare "to sail" (see further Navigation § Etymology).[2]

Definition [edit]

A person walking completely around either pole will cross all meridians, but this is not generally considered a "circumnavigation". The path of a true (global) circumnavigation forms a continuous loop on the surface of Earth separating two regions of comparable area. A basic definition of a global circumnavigation would be a route which covers roughly a great circle, and in particular one which passes through at least one pair of points antipodal to each other.[3] In practice, people use different definitions of world circumnavigation to accommodate practical constraints, depending on the method of travel. Since the planet is quasispheroidal, a trip from one Pole to the other, and back again on the other side, would technically be a circumnavigation. There are practical difficulties in such a voyage, although it was successfully undertaken in the early 1980s by Ranulph Fiennes.[4]

History [edit]

The first single voyage of global circumnavigation was that of the ship Victoria, between 1519 and 1522, known as the Magellan–Elcano expedition. It was a Castilian (Spanish) voyage of discovery. The voyage started in Seville, crossed the Atlantic Ocean, and after several stopovers rounded the southern tip of South America, where the expedition discovered the Strait of Magellan, named after the fleet's captain. It then continued across the Pacific, discovering a number of islands on its way, including Guam, before arriving in the Philippines. The voyage was initially led by the Portuguese Ferdinand Magellan, although he died during the voyage in Mactan in the Philippines in 1521. The remaining sailors continued the journey across the Indian Ocean, round the Cape of Good Hope, north along the Atlantic Ocean, and back to Spain in 1522. Only 18 men were still with the expedition at the end,[5] including the Spanish Juan Sebastián Elcano, who was its captain at the end.

Some sources suggest that Magellan had visited places east of Mactan during a previous trip, sailing east from Europe.[6] If that was true, then the two trips in combination would make him the first person to circumnavigate the Earth in longitude (possibly along with some other Portuguese and the Malay-Sumatrese Enrique of Malacca). However, that suggestion is dubious and controversial, and Magellan was not confirmed to have previously traveled east of Malacca, which means he never completed the portion of the trip between Mactan and Malacca.

In 1577, Elizabeth I sent Francis Drake to start an expedition against the Spanish along the Pacific coast of the Americas. Drake set out from Plymouth, England in November 1577, aboard Pelican, which he renamed Golden Hind mid-voyage. In September 1578, the ship passed south of Tierra del Fuego, the southern tip of South America, through the area now known as the Drake Passage. [7] [8] In June 1579, Drake landed somewhere north of Spain's northernmost claim in Alta California, which is known as Drakes Bay, California. Drake completed the second circumnavigation of the world in September 1580, becoming the first commander to lead an entire circumnavigation.

Thomas Cavendish completed his circumnavigation between 1586 to 88 in record time - in two years and 49 days; nine months faster than Drake. It was also the first deliberately planned voyage of the globe.[9]

For the wealthy, long voyages around the world, such as was done by Ulysses S. Grant, became possible in the 19th century, and the two World Wars moved vast numbers of troops around the planet. However, it was the rise of commercial aviation in the late 20th century that made circumnavigation, when compared to the Magellan–Elcano expedition, quicker and safer.[1]

Nautical [edit]

The nautical global and fastest circumnavigation record is currently held by a wind-powered vessel, the trimaran IDEC 3. The record was established by six sailors: Francis Joyon, Alex Pella, Clément Surtel, Gwénolé Gahinet, Sébastien Audigane and Bernard Stamm; who wrote themselves into history books on 26 January 2017, by circumnavigating the globe in 40 days, 23 hours, 30 minutes and 30 seconds.[10] The absolute speed sailing record around the world followed the North Atlantic Ocean, Equator, South Atlantic Ocean, Southern Ocean, South Atlantic Ocean, Equator, North Atlantic Ocean route in an easterly direction.

Wind powered [edit]

The route of a typical modern sailing circumnavigation, via the Suez Canal and the Panama Canal is shown in red; its antipodes are shown in yellow.

The map on the right shows, in red, a typical, non-competitive, route for a sailing circumnavigation of the world by the trade winds and the Suez and Panama canals; overlaid in yellow are the points antipodal to all points on the route. It can be seen that the route roughly approximates a great circle, and passes through two pairs of antipodal points. This is a route followed by many cruising sailors, going in the western direction; the use of the trade winds makes it a relatively easy sail, although it passes through a number of zones of calms or light winds.[11]

The route of a typical yacht racing circumnavigation is shown in red; its antipodes are shown in yellow.

In yacht racing, a round-the-world route approximating a great circle would be quite impractical, particularly in a non-stop race where use of the Panama and Suez Canals would be impossible. Yacht racing therefore defines a world circumnavigation to be a passage of at least 21,600 nautical miles (40,000 km) in length which crosses the equator, crosses every meridian and finishes in the same port as it starts.[12] The second map on the right shows the route of the Vendée Globe round-the-world race in red; overlaid in yellow are the points antipodal to all points on the route. It can be seen that the route does not pass through any pairs of antipodal points. Since the winds in the higher southern latitudes predominantly blow west-to-east it can be seen that there are an easier route (west-to-east) and a harder route (east-to-west) when circumnavigating by sail; this difficulty is magnified for square-rig vessels due to the square rig's dramatic lack of upwind ability when compared to a more modern Bermuda rig.[11]

For around the world sailing records, there is a rule saying that the length must be at least 21,600 nautical miles calculated along the shortest possible track from the starting port and back that does not cross land and does not go below 63°S. It is allowed to have one single waypoint to lengthen the calculated track. The equator must be crossed.[13]

The solo wind powered circumnavigation record of 42 days, 16 hours, 40 minutes and 35 seconds was established by François Gabart on the maxi-multihull sailing yacht MACIF and completed on 7 December 2017.[14] The voyage followed the North Atlantic Ocean, Equator, South Atlantic Ocean, Southern Ocean, South Atlantic Ocean, Equator, North Atlantic Ocean route in an easterly direction.

Mechanically powered [edit]

Since the advent of world cruises in 1922, by Cunard's Laconia, thousands of people have completed circumnavigations of the globe at a more leisurely pace. Typically, these voyages begin in New York City or Southampton, and proceed westward. Routes vary, either travelling through the Caribbean and then into the Pacific Ocean via the Panama Canal, or around Cape Horn. From there ships usually make their way to Hawaii, the islands of the South Pacific, Australia, New Zealand, then northward to Hong Kong, South East Asia, and India. At that point, again, routes may vary: one way is through the Suez Canal and into the Mediterranean; the other is around Cape of Good Hope and then up the west coast of Africa. These cruises end in the port where they began.[11]

In 1960, the American nuclear-powered submarine USS Triton circumnavigated the globe in 60 days, 21 hours for Operation Sandblast.

The current circumnavigation record in a powered boat of 60 days 23 hours and 49 minutes[15] was established by a voyage of the wave-piercing trimaran Earthrace which was completed on 27 June 2008. The voyage followed the North Atlantic Ocean, Panama Canal, Pacific Ocean, Indian Ocean, Suez Canal, Mediterranean Sea route in a westerly direction.

Aviation [edit]

The first aerial circumnavigation of the planet was flown in 1924 by aviators of the U.S. Army Air Service in a quartet of Douglas World Cruiser biplanes.

Since the development of commercial aviation, there are regular routes that circle the globe, such as Pan American Flight One (and later United Airlines Flight One). Today planning such a trip through commercial flight connections is simple.

The first lighter-than-air aircraft of any type to circumnavigate under its own power was the rigid airship LZ 127 Graf Zeppelin, which did so in 1929.[ citation needed ]

Aviation records take account of the wind circulation patterns of the world; in particular the jet streams, which circulate in the northern and southern hemispheres without crossing the equator. There is therefore no requirement to cross the equator, or to pass through two antipodal points, in the course of setting a round-the-world aviation record. Thus, for example, Steve Fossett's global circumnavigation by balloon was entirely contained within the southern hemisphere.[11]

For powered aviation, the course of a round-the-world record must start and finish at the same point and cross all meridians; the course must be at least 36,770 kilometres (19,850 nmi) long (which is approximately the length of the Tropic of Cancer). The course must include set control points at latitudes outside the Arctic and Antarctic circles.[16]

In ballooning, which is totally at the mercy of the winds, the requirements are even more relaxed. The course must cross all meridians, and must include a set of checkpoints which are all outside of two circles, chosen by the pilot, having radii of 3,335.85 kilometres (2,072.80 mi) and enclosing the poles (though not necessarily centred on them).[17]

Astronautics [edit]

The first person to fly in space, Yuri Gagarin, also became the first person to complete an orbital spaceflight in the Vostok 1 spaceship within 2 hours in 1961.[18]

Flight started at 63° E and ended 45° E longitude; thus Gagarin did not circumnavigate Earth completely.

Gherman Titov in the Vostok 2 was the first human to circumnavigate Earth in spaceflight and made 17.5 orbits.

Human-powered [edit]

According to adjudicating bodies Guinness World Records and Explorersweb, Jason Lewis completed the first human-powered circumnavigation of the globe on 6 October 2007.[19] [20] This was part of a thirteen-year journey entitled Expedition 360.[ citation needed ]

In 2012, Turkish-born American adventurer Erden Eruç completed the first entirely solo human-powered circumnavigation, travelling by rowboat, sea kayak, foot and bicycle from 10 July 2007 to 21 July 2012,[21] crossing the equator twice, passing over 12 antipodal points, and logging 66,299 kilometres (41,196 mi)[22] in 1,026 days of travel time, excluding breaks.[23]

National Geographic lists Colin Angus as being the first to complete a global circumnavigation.[24] However, his journey did not cross the equator or hit the minimum of two antipodal points as stipulated by the rules of Guinness World Records and AdventureStats by Explorersweb.[25] [26] [27]

People have both bicycled and run around the world, but the oceans have had to be covered by air or sea travel, making the distance shorter than the Guinness guidelines. To go from North America to Asia on foot is theoretically possible but very difficult. It involves crossing the Bering Strait on the ice, and around 3,000 kilometres (1,900 mi) of roadless swamped or freezing cold areas in Alaska and eastern Russia. No one has so far travelled all of this route by foot. David Kunst was the first verified person to walk around the world between 20 June 1970 and 5 October 1974.[28]
