Traditional navigation skills--and technology-free position finding--are still vital, though, especially when things go wrong, as they will: batteries fail, antennas go overboard, and electronics get wet. Knowledge of celestial navigation is a life-saving emergency skill; it is also a rite of initiation and its practice still a favorite pastime among serious cruisers. \u003cp\u003e\u003c\/p\u003eA bestseller for over 65 years, \u003ci\u003eCelestial Navigation\u003c\/i\u003e for Yachtsmen is a model of simplicity and clarity.
