slides expeditions of the "Ra"

Sketch of Ra II, papyrus craft with which Thor Heyerdahl tried to demonstrate the ability of the Egyptians to sail the high seas.

beam Egyptian Boats papyrus became famous and were fully technically known through the work of Norwegian anthropologist and explorer Thor Heyerdahl, who dedicated his life to researching the ancient sea migrations. When Heyerdahl in 1947 was devoted to the study of the Egyptian ships had already successfully made the famous expedition of Kon Tiki, the raft with which I wanted to test the theory that Polynesia had been populated by two successive waves of immigrants from Peru and the islands of the East, who have navigated using wooden rafts. At the end of the decade of 1960, Heyerdahl began Ra project, which involved the construction a bundle of papyrus craft, a replica of ancient Egyptian boat to cross the Atlantic with her and show that the Egyptians could have reached America. For the construction of the first Ra were used 12 tons of papyrus stalks collected in the marshes of the Nile in Sudan, and followed the plans of the Swedish historian Björn Landström. The artisans made up of Lake Chad (the only ones left in Africa) experts in shipbuilding with stems. They used a makeshift site a few miles south of Giza. The raft measuring 17.7 meters in length and 5.5 wide. Ra sailed on May 25, 1969 the port of Safi in Morocco, with Heyerdahl and a group of six anthropologists on board. Storms whipped repeatedly. Although the papyrus is not decomposed with seawater and stems were dried in the desert stretch like rubber, July 16, after a big storm, the Ra was very concerned and began to suffer an irreversible grief . Finally, broke in two and sank after a month at sea and 2,700 miles traveled. The crew was rescued by boat tracking.

Heyerdahl was not discouraged by this failure and built the Ra II , in this new ship took more account of the construction methods practiced by the Indians stems from Lake Titicaca, in Peru, and corrected the problems of Ra adds stiffness to the hull and reducing the length of three meters. The final crew was eight climbers, including Heyerdahl. The Ra II sailed from Safi on 16 May 1970 and arrived in Barbados on July 12, after traveling 3000 miles in 57 days, sailing the trade winds from the northwest. It was a great success and showed that vessels of papyrus, well built, could cross the Atlantic when sailing with the trade winds.
