Olav Heyerdahl, 28, is one of a six-person crew that set sail May 1 on a 56-foot balsa raft. Tangaroa, named for the Polynesian god of the sea, is equipped with a hand-woven sail, thatched hut, GPS equipment and solar electric panels.
The voyagers believe their raft is more authentic than the historic Kon-Tiki, which sailed from South America to Tahiti in 101 days. Unlike Kon-Tiki, Tangaroa can sail against the wind.
Readers can follow the expedition's progress on its webpage http://pub.tv2.no/nettavisen/friluftsliv/tangaroa/, although it will be most effective for readers of Norwegian.
