[1] The goal of the expedition was to show that balsawood rafts can be sailed across long distances, and to collect scientific data in the southeast Pacific.
On the return journey from Easter Island to South America, the expedition was terminated after 71 days at sea due to difficult weather conditions.
Like the Kon-Tiki, Rahiti Tane and Tupac Yupanqui were built from balsawood transported from Ecuador to SIMA, the Peruvian Army's shipyard in Callao, Lima.
[4] The Kon-Tiki2 Expedition had crew from many nations: Norway, Russia, UK, Mexico, New Zealand, Sweden, and Peru.
On the return journey, Pedro De La Torre was responsible for the technical equipment and the scientific work.
