This Waypoint Directory is a useful guide for anyone who navigates with Decca or GPS, whether under sail or power. It contains 60 coastal approach charts for the English and French sides of the English Channel, showing the positions of over 500 carefully chosen and precisely specified waypoints. Alongside each chart is a table giving the latitude and longitude of each waypoint, as well as details of the coastal dangers to take into account when using the waypoints. Having selected the best waypoints for a required passage, the navigator can enter their latitudes and longitudes directly into a Decca or GPS memory and build up a route or sailplan quickly and easily.
