Wayfinding Voyage

How Pacific Navigators Find Their Way

Wayfinding is the practice of traveling across the open ocean by carefully observing the natural world. Pacific navigators traditionally traveled without GPS, maps or magnetic compasses. Instead, they learned to read the sky, ocean, wind, wildlife and islands. This knowledge was taught over many years by master navigators and is still practiced today.

At night, navigators use the stars to keep a steady direction. Particular stars rise and set in predictable places along the horizon. A navigator memorizes these positions and follows a “star path” toward a destination. At sunrise and sunset, the Sun helps confirm direction.

Swells are long, rolling waves created by distant winds. They can move in the same direction for days. A skilled navigator feels the swells against the canoe and uses them to stay on course, even when clouds hide the stars.

Marshallese navigators made stick charts to model how swells bend, cross and change near islands. They memorized the charts on land before a voyage. Carolinian navigators use a system called etak. They imagine a reference island to one side to track progress across the sea.

Islands often occur in groups, creating a larger target than one small island alone. Navigators watch for birds, clouds gathered above islands, a glow above a lagoon, drifting plants and changes in the color or movement of the water.

In 1976, Mau Piailug of Satawal navigated the canoe Hōkūleʻa about 2,500 miles from Hawaiʻi to Tahiti without modern instruments. He later taught Native Hawaiian navigator Nainoa Thompson, who helped revive long-distance Hawaiian wayfinding. Not every Pacific tradition was recorded the same way, so historians avoid assuming that all navigators used identical methods.
