If you're interested in learning about this kind of navigational knowledge, about how Pacific Islander sailors could hop from island to island over the horizon without maps, I recommend reading The Last Navigator. It is also an interesting story told in the first person by the author going to learn the art of navigation and observing a culture being pushed aside.

A third good book is Vaka Moana, Voyages of the Ancestors: The Discovery and Settlement of the Pacific

We, the Navigators by David Lewis is another good book on the topic
