From the Back Cover

"A practical, convenient, and economical solution for the mariner who wants a backup system to GPS that contains all the essential instructions and data."—Foundation for the Art of Navigation

Your All-in-One Navigation Tool Kit

Celestial navigation remains an essential skill for every mariner who ventures out of sight of land. In this era of electronic navigation, it is the perfect backup system, enabling you to determine your position when the GPS malfunctions or your boat loses electrical power.

Here in one volume is every bit of information you need to understand the process, take sights, and find your location anywhere in the world. Compiled for beginning and experienced celestial navigators alike, and elegantly designed on the assumption that 1-mile precision is perfectly adequate for backup navigation, this handy volume replaces $300 worth and thousands of pages of guides, tables, and almanacs.

The Complete On-Board Celestial Navigator includes:

• A clear, concise primer/refresher that explains the entire process
• A five-year nautical almanac (2007–2011) for determining precise star, sun, moon, and planet locations at the time of sighting
• A star finder
• Sight reduction tables for crunching the numbers and producing a fix anywhere in the world

"The only complete self-contained work available. When your electronic navigation fails, 'steering by the stars' will guide you safely to your destination."—Sydney Afloat (Australia)

Brilliant!
Lots of books have been written on this subject, not an easy one for the beginner to understand, and all so complicated requiring other books to be purchased as references. Not this book, it has it all, every table you need for successful position-plotting, until the end of 2011. All it lacks is an idiot's guide approach, but then all these kind of books use complex language and jargon for what should be a fairly straightforward process. I think the ideal book on Cel Nav has still to be written, but this one is the closest I've seen. I will use it along with the other two I already have, and perhaps then I can come up with the idiot's guide I was looking for in the first place.

Very good
I am a professional captain and am usually blessed with the latest in navigation aids - plus back-ups and of course a sextant. This book not only provides a concise and easy to follow aide memoir for the rusty navigator but is a huge saving on both cost and bookshelf space in eliminating the need for sight reduction tables and almanac. I am very pleased with it.The Complete On-Board Celestial Navigator, 2007-2011 Edition: Everything But the Sextant
