All crew members were taken aboard a Japanese freighter, and later transported to shore by the Chilean Armada. Expedition leader Torgeir Higraff chose to terminate the expedition to avoid risking the life of crew members. The expedition built and sailed two balsawood rafts: "Rahiti Tane" and "Tupac Yupanqui". The rafts were similar to the "Kon-Tiki" raft built by Thor Heyerdahl in 1947. Like the "Kon-Tiki", "Rahiti Tane" and "Tupac Yupanqui" were built from balsawood transported from Ecuador to SIMA, the Peruvian Army's
Thor Heyerdahl evidence suggesting contact between South America and Polynesia. The "Kon-Tiki" smashed into the reef at Raroia in the Tuamotus on August 7, 1947, after a 101-day, 4,300-nautical-mile (5,000-mile or 8,000 km) journey across the Pacific Ocean. Heyerdahl had nearly drowned at least twice in childhood and did not take easily to water; he said later that there were times in each of his raft voyages when he feared for his life. "Kon-Tiki" demonstrated that it was possible for a primitive raft to sail the Pacific with relative ease and safety, especially to the west (with the trade winds). The raft
