Polynesian Voyaging Society

Using replicas of traditional double-hulled canoes, PVS undertakes voyages throughout Polynesia navigating without modern instruments. After an attempted voyage to Tahiti in 1978 was aborted when the Hokuleʻa capsized near Lānaʻi and crew member Eddie Aikau was lost at sea, Piailug trained Nainoa Thompson in the ancient navigation methods. Two years later in 1980, Thompson replicated the successful 1976 voyage to Tahiti, becoming the first modern Hawaiian to master the art of Micronesian navigation.
