A beginner's text, giving straightforward explanations of everything you need to know to find your way across the bay or around the globe, this book takes you step-by-step through celestial navigation. You'll learn how to use the Nautical Almanac, chronometer, sextant, star finder, and both the H.O. 229 and assumed altitude sight reduction tables. The book features specially designed celestial navigation workforms developed from the course material the author has used in his Weems & Plath -- sponsored navigation course.
