Those elements of pilotage and navigation which are of fundamental importance for managing the passage of small craft - both within sight of land and offshore - are handily summarized in this clearly written text. Starting with the care and reading of a chart, the student is presented with simple, step-by-step instructions in the skills and information necessary to navigate small boats. A concise treatment of nautical astronomy, necessary as a foundation for a complete understanding of celestial navigation, is also included. The three primary approaches to sight reduction - by calculation, short method tables, and inspection tables - are presented in an orderly way for easy understanding. In addition, the Loran C system is explained precisely, together with the hyperbolic grid concept. To make sure the lessons have been mastered, there are appropriate practical exercises directed towards those conditions and operating situations likely to be encountered by fishermen and other small boat operators. This approach provides an effective and appealing way to learn, which is more interesting than the traditional navigation text. The many illustrations throughout the book enhance its usefulness for the boat operator. --- from book's back cover - from Amzon
