In 1995 Hawaiiloa and five other double canoes, reconstructions of ancient Polynesian craft, set sail from the rugged Marquesas archipelago and headed north across the equator to Hawai`i. Their Hawaiian and Polynesian crews were sailing to commemorate the original discovery of Hawaii some fifteen centuries ago and to celebrate the revival of long-distance voyaging that had begun during the 1960s. In learning how to sail and navigate in the old way they had rediscovered their own identity as worthy heirs to a great seafaring tradition. In "Sailing in the Wake of the Ancestors," anthropologist Ben Finney, who helped start the revival, tells the story of how Hawaiians and other Polynesians have struggled to become deep-sea voyagers again, and how their experiences are helping them to face contemporary problems with renewed pride and courage.  (PAC178, $19.95)
