Reading star compasses, ocean swells, and seabird flight arcs across the Pacific.
ALong before European vessels ventured out of sight of land, Polynesian navigators sailed double-hulled voyaging canoes across thousands of kilometres of open Pacific without sextants or magnetic compasses. Mastery rested on memorising a mental star compass mapping rising and setting azimuths of over two hundred stars.
BWhen cloud decks obscured night skies, wayfinders crouched inside the hull to feel subtle pitch and roll patterns caused by primary ocean swells refracting around distant invisible atolls. Modern GPS reconstructions aboard the replica canoe Hokule'a verified that traditional swell-reading sustained dead-on headings within two degrees.
Write TWO WORDS: Under cloudy skies, Polynesian navigators read refracted ocean _______ from inside the canoe hull.
