Show Notes

The Kon-Tiki expedition, led by Norwegian explorer and ethnologist Thor Heyerdahl, reached Raroia in the Tuamotu Archipelag near Tahiti, on 7th August, 1947. The 45-foot-long balsa wood raft, with a five-man crew, had completed a 4,300-mile, 101-day journey from Peru. 

Heyerdahl wanted to prove his (now discredited) theory that prehistoric South Americans could have colonized the Polynesian islands by drifting on ocean currents. The Kon-Tiki was made of indigenous materials and designed to resemble rafts of early South American Indians, although the expedition carried some modern equipment, such as a radio, watches, charts, sextant, and metal knives. While crossing the Pacific, the sailors encountered storms, sharks and whales.

In this episode, Arion, Rebecca and Olly explain why Heyerdahl’s hypothesis of a South American origin of the Polynesian peoples is rejected today; marvel at his bold use of eye-catching graphic design; and expose how the crew’s food rations weren’t all that they seemed…
