Pius "Mau" Piailug

Pius "Mau" Piailug (1932-2010) was a master navigator from the small coral island of Satawal in Micronesia, who became legendary for preserving and sharing traditional Polynesian wayfinding techniques. Born in Weiso village on Satawal, a 1.5-mile by 1-mile coral island with about 600 residents, Mau learned the ancient art of navigation through decades of apprenticeship under his grandfather Raangipi in the Weriyeng wayfinding system. Mau earned the title of master navigator (palu) by age eighteen, mastering a complex system that relied on reading stars, planets, moon phases, winds, ocean swells, wave patterns (bugoloa), clouds, birds, and fish behavior. As Western influence grew in Micronesia, Mau became concerned that these ancient navigation traditions would be lost forever. In an unprecedented decision that broke with traditional cultural restrictions, he chose to share his sacred knowledge with outsiders. In 1976, Mau navigated the Polynesian Voyaging Society's reconstructed double-hulled canoe Hōkūleʻa on a historic 6,000-nautical-mile voyage from Hawaii to Tahiti without any modern instruments. The 34-day journey with a crew of 15 sailors empirically proved that intentional trans-oceanic voyaging was possible using traditional techniques, disproving theories that Pacific islands were populated by accidental drift. This voyage sparked a revival of Polynesian navigation traditions that had been dormant for approximately 600 years. Mau continued his work with the Polynesian Voyaging Society, returning in 1979 and 1980 to train navigators including Nainoa Thompson, who became his most accomplished student. Through his teaching and the success of the Hōkūleʻa voyages, Mau helped preserve invaluable maritime knowledge while fostering cultural exchange between Micronesian and Polynesian communities. His legacy lives on through the navigators he trained and the continued voyages of traditional Pacific canoes.
