The Barefoot Navigator is the most innovative book about marine navigation for decades. Jack Lagan believes there is nothing so valuable at sea as standing on a deck and just knowing where you are using special knowledge about the sea and the sky and using your senses--in other words, practical technology-free navigation.

Part 1 looks at the navigation achievements of the ancient seafarers--the Pacific islanders, the Vikings, the Phoenicians, the Arabs and the Chinese. Just how did the South Pacific islanders manage to populate every habitable island in an area bigger than North America? And did the Phoenicians really circumnavigate Africa 2,000 years before Vasco de Gama?

Part 2 explains how to use the wind, swell, sun and stars to estimate position and hold a course. And how sea breezes, isolated clouds and seabirds can make a landfall safer.

Part 3. shows how you can use DIY devices to calculate latitude, obtain bearings and estimate longitude.

Part 4 describes how all these techniques can be used in survival situations

The Barefoot Navigator is about wayfinding from what you can see around you and what you have in your head. It will fascinate navigators and landlubbers alike.
