Nautical Almanac for the Year 1981
The Nautical Almanac for the Year 1981 for Study and Exam Preparation
Although data in this book is no longer valid for navigation, it is preserved in print because many training programs (including USCG and US Navy ) use examples from 1981 to teach celestial navigation. USCG license exams require data from this almanac. It is helpful for study purposes and exam preparation.
