Cruising sailors who venture beyond the sign of land on either sailboats or powerboats should have a thorough knowledge of celestial navigation to allow them to plot and follow a course. On long sailing races, this facility becomes critically important to winning. Celestial navigation, an exact science, is not the mystery it has been made out to be. As the author shows, all the navigator needs in the way of equipment is a relatively inexpensive sextant specific recommendations are given and a reasonably accurate timepiece. All the rest is in this book, which is a complete navigation system in itself. Each step in this system is clearly explained, and the book is illustrated throughout by simple yet precise line drawings and charts.
