[.ca] Dutton's Nautical Navigation (ISBN 155750248X)

Not essential to navigation, but most desirable:
The essentials to celestial navigation are a sextant, the current nautical almanac, and an accurate timepiece correctible to Greenwich Mean Time (Coordinated Universal Time.) Given those things and some basic instruments and charts, and of course the requisite knowledge and skills to use them, you can find your way on the trackless oceans of the world. If you lack the knowledge and skills to use the above instruments and objects, you can learn to use them, with the application of the necessary dilligence and intelligence, in either of two volumes, this one and the 'American Practical Navigator.' The latter comes in two volumes, and is published by the U.S. government (Defense Mapping Agency Hydrographic Center). Both volumes are used as textbooks by the United States Naval Academy and the United States Power Squadrons, to teach celestial navigation. I am a full certificate member of the latter organization. I recommend them to you. Joseph Pierre, N Author of THE ROAD TO DAMASCUS: Our Journey Through Etermnity
