In 1970, Thor Heyerdahl and his crew used this raft to cross the Atlantic from Morocco to the Barbados to demostrate that earlier cultures could have also have crossed in primitive craft.

"In 1969 and 1970, Heyerdahl built two boats from papyrus and attempted to cross the Atlantic Ocean from Morocco in Africa. Based on drawings and models from ancient Egypt, the first boat, named Ra (after the Egyptian Sun god), was constructed by boat builders from Lake Chad using papyrus reed obtained from Lake Tana in Ethiopia and launched into the Atlantic Ocean from the coast of Morocco. After a number of weeks, Ra took on water after its crew made modifications to the vessel that caused it to sag and break apart. The ship was abandoned and the following year, another similar vessel, Ra II, was built of totora by Demetrio, Juan and Jose Limachi from Lake Titicaca in Bolivia and likewise set sail across the Atlantic from Morocco, this time with great success. The boat reached Barbados, thus demonstrating that mariners could have dealt with trans-Atlantic voyages by sailing with the Canary Current.[18]
The book The Ra Expeditions and the film documentary Ra (1972) were made about the voyages. Apart from the primary aspects of the expedition, Heyerdahl deliberately selected a crew representing a great diversity in race, nationality, religion and political viewpoint in order to demonstrate that at least on their own little floating island, people could cooperate and live peacefully. Additionally, the expedition took samples of marine pollution and presented their report to the United Nations."
