20 October 2009 by Tristan Gooley

using colour to gauge sea depthThis photo shows the colour difference as the water shallows over a sandbank of the beach at West Wittering. Colour has been used by nautical navigators since the first boats went to sea. In places where the water was too murky to use colour, like rivers, other techniques were developed. There are images dating back four thousand years that show ancient Egyptian boats plying the Nile with a man standing at the bow with a sounding pole. The pole gave an instant and very physical reading of depth.

Welcome to the home of natural navigation on the Internet.

Natural navigation is the art of being able to find your way solely by using nature. It encompasses using the sun, moon, stars, weather, water, land, sea, plants and animals.

The Natural Navigator is the school set up by Tristan Gooley to research and teach natural navigation. It is also the title of his book on the subject.
