The Polynesians were the greatest ocean navigators in history, settling a third of the planet — thousands of islands across the Pacific — with no instruments at all. Their compass was the sky itself.
A wayfinder memorised where hundreds of stars rise and set on the horizon, and steered by them through the night. To hold it all in memory, the Hawaiian tradition groups the brightest into four great star lines (nā kūlia) — arcs of stars that rise together and sweep across the sky in turn through the year.
Along them ride the wayfinder's key marks: Hōkūleʻa (Arcturus), the star that passes straight overhead at Hawaiʻi; Hōkūpaʻa (the North Star) and Hānaiakamalama (the Southern Cross) to hold a course; and Ka Makau Nui o Māui — the great fishhook (Scorpius) with which the demigod hauled the islands from the sea.

Pick a figure to see it over the real stars — with its story and the Chinese mansion & Indian nakshatra it shares.
Where a star rises is a bearing. Every star rises at the same point on the eastern horizon each night and sets at the mirror point in the west. The wayfinder divides the horizon into 32 houses (like our compass points) grouped in four quadrants: Koʻolau (NE), Malanai (SE), Kona (SW), Hoʻolua (NW).
To hold a course, you keep a known star rising or setting off a fixed point of the canoe. As one star climbs too high, the next in its "house" takes over — a chain of steering stars all night long.
Between the stars, the wayfinder also reads the swells, the wind, the clouds and the flight of birds — the whole ocean and sky as one instrument.
Figures follow the Hawaiian star-line system of the Polynesian Voyaging Society (Nainoa Thompson), drawn from their bright stars at Hipparcos J2000 positions; Hawaiian names are given with their Western stars. Sky-lore varies across Polynesia (Māori, Tahitian, Sāmoan and others share many of these stars under their own names). Shared-star links use the same coordinates as The Chinese Sky and The Indian Sky. Live view: The Polynesian Sky Tonight.
