[[Image:KonTikiInMuseum.jpg|thumb|The raft in the Kon-Tiki Museum, Oslo]]
'''''Kon-Tiki''''' is the raft used by [[Norway|Norwegian]] explorer and writer [[Thor Heyerdahl]] in his 1947 expedition across the [[Pacific Ocean]] from [[South America]] to the [[Polynesia|Polynesian islands]]. It was named after the [[Inca]] [[sun god]], [[Viracocha]], for whom "Kon-Tiki" was said to be an old name. ''Kon-Tiki'' is also the name of the popular book that Heyerdahl wrote about his adventures.
Heyerdahl believed that people from South America could have settled Polynesia in [[pre-Columbian]] times. His aim in mounting the ''Kon-Tiki'' expedition was to show, by using only the materials and technologies available to those people at the time, that there were no technical reasons to prevent them from having done so. (Although the expedition carried some modern equipment, such as a radio, watches, charts, sextant, and metal knives, these were incidental to the purpose of proving that the raft itself could make the journey.)
The ''Kon-Tiki'' expedition was funded by private loans, along with donations of equipment from the US Army. Heyerdahl and a small team went to [[Peru]], where, with the help of dockyard facilities provided by the Peruvian authorities, they constructed the raft out of [[balsa]] logs and other native materials in an indigenous style as recorded in illustrations by Spanish [[conquistadores]]. The trip began on [[April 28]], [[1947]]. Heyerdahl and five companions sailed the raft for 101 days over 4,300 miles across the Pacific Ocean before smashing into a [[reef]] at [[Raroia]] in the [[Tuamotu Islands]] on [[August 7]], [[1947]]. The crew made successful landfall and all returned safely.
The book ''Kon-Tiki'' was a best-seller, and a documentary [[motion picture]] of the expedition won an [[Academy Award for Documentary Feature|Academy Award]] in 1951.
The original ''Kon-Tiki'' is now on display in the Kon-Tiki Museum in [[Oslo]].
== Crew ==
The ''Kon-Tiki'' was crewed by six men, all Norwegian except for Bengt Danielsson, who was from Sweden.
*'''[[Thor Heyerdahl]]''' (1914–2002) was expedition leader.
*'''Erik Hesselberg''' (1914–1972) was the navigator and artist. He painted the large Kon-Tiki figure on the raft's sail.
*'''[[Bengt Danielsson]]''' (1921–1997) took on the role of steward, in charge of supplies and daily rations. Danielsson was a sociologist interested in [[human migration|human migration theory]]. He also served as translator, as he was the only member of the crew who spoke Spanish.
*'''[[Knut Haugland]]''' (1917–) was a radio expert, decorated by the British in World War II for actions in the [[Norwegian heavy water sabotage]] that stalled Germany's plans to develop an [[atomic bomb]].
*'''[[Torstein Raaby]]''' (1920–1964) was also in charge of radio transmissions. He gained radio experience while hiding behind German lines during WWII, spying on the German battleship ''[[German battleship Tirpitz|Tirpitz]]''. His secret radio transmissions eventually helped guide in Allied bombers to sink the ship.
*'''Herman Watzinger''' (1910–1986) was an engineer whose area of expertise was in technical measurements. He recorded meteorological and hydrographical data while underway.
==Construction==
The main body of the raft was composed of nine [[balsa]] tree trunks up to 13.7 metres (45 ft) long, 60 cm (2 ft) in diameter, lashed together with 3.175 cm (1¼ inch) [[hemp]] ropes. Cross-pieces of balsa logs 5.5 m (18 ft) long and 30 cm (1 ft) in diameter were lashed across the logs at 1 m (3 ft) intervals to give lateral support. [[Pine]] splashboards clad the bow, and lengths of pine 2.5 cm (1 inch) thick and 60 cm (2 ft) long were wedged between the balsa logs and used as [[centerboard]]s.
The main mast was made of lengths of mangrove wood lashed together to form an A-frame 8.8 m (29 ft) high. Behind the main-mast was a cabin of plaited bamboo 4.2 m (14 ft) long and 2.4 m (8 ft) wide was built about 1.21-1.51 m (4-5 feet) high, and roofed with banana leaf thatch. At the stern was a 5.8 m (19 ft) long steering oar of mangrove wood, with a blade of fir.
The main sail was 4.6 m by 5.5 m (15 by 18 feet) on a yard of bamboo stems lashed together. Photographs also show a top-sail above the main sail, and also a mizzen-sail, mounted at the stern.
The raft was partially decked in split bamboo. No metal was used in the construction.
==Stores==
The ''Kon-Tiki'' carried 250 litres of water in bamboo tubes. For food they took 200 [[coconut]]s, [[sweet potato]]es, [[calabash|bottle gourds]] and other assorted fruit and roots. The [[U.S. Army Quartermaster Corps]] of the [[US Army]] provided [[field ration]]s, tinned food, and survival equipment. In return, the ''Kon-Tiki'' explorers reported on the quality, and utility of the provisions. They also caught plentiful numbers of fish, particularly [[flyingfish|flying fish]], "[[mahi-mahi|dolphin]]", [[yellowfin tuna]] and shark.
==Communications==

* Transmitter: unknown
* As an emergency backup they also carried a German Mark V [[transceiver]] originally re-created by the [[Special Operations Executive|SOE]] in 1942.
==The Voyage==
The ''Kon-Tiki'' left [[Callao]], [[Peru]], on the afternoon of April 28, 1947. It was initially towed 50 miles out to open water by the Fleet Tug ''Guardian Rios'' of the [[Peruvian Navy]]. The ship then sailed roughly west carried along on the [[Humboldt Current]]. The crew's first sight of land was the atoll of [[Puka-Puka]] on July 30. They made brief contact with the inhabitants of [[Fangataufa|Angatau Island]] on August 4, but were unable to land safely.
Three days later, on August 7, the raft struck a reef and was eventually beached on an uninhabited islet off [[Raroia]] Island in the [[Tuamotus|Tuamotu]] group. The team had travelled a distance of around 3,770 nautical miles (c.6980 km) in 101 days, at an average speed of 1.5 knots.
After spending a number of days alone on the tiny islet, the crew were greeted by men from a village on a nearby island who arrived in canoes, having seen washed-up flotsam from the raft. The crew were taken back to the native village, where they were feted with traditional dances and other festivities. Finally the crew were taken off Raroia to [[Tahiti]] by the French schooner ''Tamara'', with the salvaged ''Kon-Tiki'' in tow.
== Discoveries: Marine Life ==
The ''Kon-Tiki'' explorers discovered the legendary [[snake mackerel]] (Latin name Gempylus) and had a rare sighting of the [[whale shark]]. Heyerdahl had two experiences with the Gempylus. The first was at night, when the snake mackerel was washed into Torstein's (one of the crew members) sleeping bag, the second was also at night, when the Gempylus tried to attack the lantern. The whale shark, huge in size, hence its name, was so big that as it swam under the raft the explorers could see its huge, flat head on one side and its tail on the other. After about an hour of the whale shark circling the raft, a crew member rammed a harpoon into its skull. The whale shark simply broke the harpoon and swam away.
== Anthropology ==
{{Mergeto|Thor Heyerdahl's theory of Polynesian origins|date=December 2007}}
While this was an interesting experiment that demonstrated the seaworthiness of Heyerdahl's raft, his theory of the Polynesians' origins has never gained acceptance by [[anthropology|anthropologists]].<ref>Robert C. Suggs ''The Island Civilizations of Polynesia'', New York: New American Library, p.212-224.</ref> Physical and cultural evidence had long suggested that Polynesia was settled from west to east, migration having begun from the [[Asia]]n mainland, not South America. In the late 1990s, [[genetics|genetic]] testing found that the [[mitochondrial DNA]] of the Polynesians is more similar to people from southeast Asia than to people from South America, showing that their ancestors most likely came from Asia.
It should be noted, however, that Heyerdahl claimed the race that settled Polynesia from South America was a white race that was distinct from the South Americans, and had in fact been driven from those shores. Therefore, it would be expected that the DNA of the Polynesians would be dissimilar to that of South Americans.
Thor Heyerdahl never set out to prove that the ''current'' Polynesians were descended from South America. According to Heyerdahl, some Polynesian legends say that Polynesia was originally inhabited by two peoples, the so-called long-eared and the short-eared. In a bloody war, all the long-eared peoples were eliminated and the short-eared people assumed sole control of Polynesia. Heyerdahl asserted that these extinct people were the ones who could have settled Polynesia from the Americas, not the current, short-eared inhabitants. One of the problems with this argument is that traditions involving long-ears and short-ears are found only at [[Easter Island]], and are unknown in the rest of Polynesia.
Heyerdahl further argues in his book ''[[American Indians in the Pacific]]'' that the current inhabitants of Polynesia migrated from an Asian source, but via an alternate route. He proposes that Polynesians traveled with the wind along the North Pacific current. These migrants then arrived in British Columbia. Heyerdahl called contemporary tribes of British Columbia, such as the [[Tlingit]] and [[Haida]], descendants of these migrants. Heyerdahl claimed that cultural and physical similarities existed between these British Columbian tribes, Polynesians, and the Old World source. Heyerdahl's claims aside, however, there is no evidence that the Tlingit, Haida or other British Columbian tribes have any particular affinity with Polynesians. Their morphologically complex languages are about as far from Austronesian and Polynesian languages as it is possible to be, and their cultures evince links to the rest of the peoples of North America.
Anthropologist Robert C. Suggs included a chapter on "The Kon-Tiki Myth" in his book on [[Polynesia]]. He concludes:
:"The ''Kon-Tiki'' theory is about as plausible as the tales of [[Atlantis]], [[Mu (lost continent)|Mu]], and "Children of the Sun." Like most such theories it makes exciting light reading, but as an example of scientific method it fares quite poorly.<ref>Robert C. Suggs, ''The Island Civilizations of Polynesia'', New York: New American Library, p.224.</ref>

==New data on chicken migration==
{{seealso|Pre-Columbian trans-oceanic contact}}
In 2007, evidence was released by the [[University of Auckland]] showing that a specific mutation in chickens native to Samoa and Tonga was seen in chicken bones found in [[Chile]] and [[radiocarbon dating| dated]] to about 1400 AD. This provides very strong evidence that there was trade between Polynesia and South America, though the researchers suspect that the trade originated from Polynesia, not South America.<ref>{{Cite journal

*It was parodied in an episode of [[Tiny Toon Adventures]] called ''Kon-Ducki''. It featured [[Plucky Duck]] as Pluck Heyerdahl, [[Hamton J. Pig]] as his assistant Koom-bye-ah, and [[Sweetie Pie]]. Pluck attempts to prove that he is able to, like his ancestors from the 1970s, sail on a [[raft]] apparently filled with [[ABBA]] [[8-track cartridge|8-track]]s and [[Screaming Yellow Zonkers]] and make it to [[Salinas, California]].
*In the ''[[Star Trek: Deep Space Nine]]'' episode, "[[Explorers (DS9 episode)|Explorers]]," [[Benjamin Sisko]] and his son go on a [[solar sail]]ing voyage on a [[spacecraft]] based on ancient [[Bajor]]an design to see if an old tale of a Bajoran successfully sailing to [[Cardassia]] was possible.
*It is the book Holly reads to Kit in their treehouse in [[Terrence Malick]]'s ''[[Badlands (film)|Badlands]]''.
*Musically, it inspired the 1961 track [[Kon-Tiki (song)| Kon-Tiki]] by [[The Shadows]], and the 2007 album track 'The Kon-Tiki Expedition' by the [[Portico Quartet]].
*It was mentioned in an episode of the show The Oblongs where Bob Oblong was creating a replica of the Kon-tiki out of wood when his son, Milo told him it was made out of reeds.
== Tangaroa Expedition ==
[[Image:Tangaroa 1.jpg|thumb|175px|Tangaroa anchored by [[Stavern]], Norway]]
On [[April 28]], [[2006]], a [[Norway|Norwegian]] team attempted to duplicate the ''Kon-Tiki'' voyage using a newly-built raft, the Tangaroa, named after the Māori sea-god [[Tangaroa]]. Again based on records of ancient vessels, this raft used relatively sophisticated [[square sail]]s that allowed sailing into the wind, or [[tacking]].<ref name="AP 2006-04-29">{{cite news
