All about the adventures of the 20th-century anthropologist Thor Heyerdahl, the Kon-Tiki Museum is named after the balsa wood raft that Heyerdahl sailed from Peru to Polynesia in 1947. 

His purpose for taking on this perilous journey was to prove that Polynesians had emigrated to the Central and South Pacific from South America.

In another daring expedition Heyerdahl sailed from Morocco to Barbados on the papyrus reed boat Ra II to prove that the Ancient Egyptians could have crossed the Atlantic.
