This famous introduction to navigation omits theory, trigonometry, and confusion. Since 1967, the first edition has been one of the best known, best loved primers on the subject. It is a straightforward presentation of what to do and how to do it using the Nautical Almanac. The appendix contains the Almanac pages needed to work every example in the book, so that no additional reference book is needed for study purposes. One of the best books we know of for the beginner.
