This guide to celestial navigation has grown from the author's experience gained through many years of teaching navigation. It is intended to answer the need for a quick, easy and thorough explanation with realistically worked problems, of the practice of celestial navigation at sea, using simple and inexpensive equipment. Accompanied by sextant and the Nautical Almanac, celestial navigation remains an extremely important method of navigation on a yacht, ocean liner, or man-of-war. If electronic devices fail, celestial navigation is a natural substitute and, in many cases, more accurate! Softcover. 130pgs. 2010.
