ABOUT CELESTIAL NAVIGATIONS BY DOMINIQUE PRINET
Celestial Navigation is an excellent instructional tool that has grown out of all the courses given by Dominique Prinet, a certified Instructor-Evaluator for Sail Canada who taught celestial navigation for close to 15 years. It has benefitted from the thoughtful contributions of over 100 students. The manual is designed to help navigators prepare for the official tests by Sail Canada, The Royal Yachting Association, and the American Sailing Association, in class or by home study.

This manual is specifically designed to help students understand the concepts of Celestial Navigation and the logic behind each step. Through clear graphics and numerous examples, it demonstrates the simple calculations required, which are basic additions or subtractions of angles and times, as well as straight interpolations.
