‘Barefoot navigation: 5,000 years in the making.' Barefoot Navigator introduces us to a unique take on navigation – using the skills of the ancients and technology-free techniques, we learn how to navigate using the sun, sea, wind and stars, and even the flight patterns of ocean birds. The first part of this absorbing book recounts a colourful history of seafarers and their navigation techniques. How did the Polynesians manage to populate an area of ocean larger than North America simply by analysing clouds,currents and wind direction? How did the Vikings routinely travel on the notorious stretches of water between Iceland, Greenland and Scandinavia? The second part shows how to use these ancient techniques to supplement today’s navigational hardware, especially in survival situations. Fascinating history, useful advice, enjoyable writing, and different to every other navigation reference out there, this second edition has been beautifully packaged in a hardback format, with new illustrations and thoroughly revised text.
