Product Description
Traditional navigation with a sextant, an almanac, and a book of tables is still thriving, even with the availability of accurate, cheap GPS receivers. Batteries sometimes go dead, and electronic devices fail, especially in salt air. Also, it can be satisfying, and fun, to work out a position and plot it, all on your own - but getting good at it requires some practice. 100 Problems is a self-contained book of realistic celestial navigation problems, including excerpts of all the necessary Nautical Almanac pages and sight-reduction table, with answers and explanations. All of the regularly encountered navigation situations are covered, as well as those that are used only occasionally and whose routines may have been forgotten, such as the backsight, shooting an unknown body, finding Venus in daylight and storm avoidance. Procedures for all the needed methods are outlined in an appendix, for review and for reference, and a sight-reduction form is included. It may be photocopied, for non-commercial use. In the problems, emphasis is on actual conditions at sea, so sometimes sights are poor or planned-for bodies are not visible. Errors are made - and an occasional blunder - as in real life.

The text arrived quickly and in good shape. The material got its arms around the subject very, very nicely; The artwork was outstanding. But I think the presentation could be strenghtened with inclusion of intermediate mathematical steps

I am in the process of teaching myself Celestial Navigation. I bought this book to help my learning process by having problems with answers to work through. And therein lies the problem. I applaud Mr. Gray's approach to set up realistice navigation problems. However, only THE ANSWER is given. Here we have a multi-step problem involving many aspects of navigation and by only giving the answer without showing solutions or partial solutions your left twisting in the wind if you didn't come up with the answer. You have no guidance on where you have erred. This has been extremely frustrating. It would have been so easy for the book to have at least included filled out sight redution forms for each problem. This addition would have enabled a "just learning neophyte" to see where his errors were. If your are an accomplished celestial navigator looking for practice or have access to an expert to mentor you than the book would be of value. To the beginner trying to learn the craft it comes up very short....too bad, it could
be so much better. I would have gladly paid more for additonal pages that showed the solution process for the problems.

Even in a world with accurate and cheap GPS receivers, traditional navigation with a sextant, an almanac, and a book of tables is still an important skill - sometimes batteries go dead or electronic devices fail, especially in salt air! Written by experienced navigator Leonard Gray, 100 Problems In Celestial Navigation: Self Contained - With Answers is a compendium of realistic navigation problems, including excerpts of all required Nautical Almanac pages and sight-reduction tables, complete with answers and explanations. These problems cover all regularly encountered navigation situations, as well as those that are only occasionally used and often forgotten, such as backsight, shooting and unknown body, finding Venus in daylight, and storm avoidance. A superb manual for safely practicing and honing one's navigational skills.
