The 12th edition of this bestselling textbook is proof of the success of Mary Blewitt's concise and clear style in explaining a particularly difficult skill, and it has been the bible for many generations of ocean navigators. Since this book was first published, the huge advances in electronic navigation has transported most offshore navigators to a world of press-button convenience. However, there is still a vital need for traditional skills when things go wrong: batteries can fail, aerials go overboard, and electronics have been known to get wet. A bestseller for over 50 years, Celestial Navigation for Yachtsmen is a model of simplicity and clarity. The worked examples require only straightforward addition and subtraction, which explains why this book has truly earned its reputation for admirable conciseness and making a tricky subject easy to understand.

[Winner of the2011 Dan Poynter Global eBook Award in the non-fiction category] Some time ago, Gene Grossman signed on as a crew-member with some friends of his who were delivering a large sailboat with no navigation electronics from Marina del Rey California, through the Panama Canal, to a charter company’s tropical island location. On the evening of departure, Gene asked the young skipper (Ron) which crew-member was going to be acting as navigator. Ron answered “I am,” Gene responded, “Oh, I didn’t know you knew celestial navigation.” Ron said “I don’t, but I will by the time we get down to Baja.” When Gene asked Ron how he intended to learn celestial navigation in the next week or so, Ron responded, “No problem, Gene, you’re going to teach it to me.” At that point in time Gene did not know anything about celestial navigation, and when he confessed that lack of knowledge, Ron said, “that’s okay; I’ve got some books about it on board, and I know you went to college, so you can learn it and teach it to me.” Gene was relieved of ‘watch’ duty and spent the next couple of weeks immersing himself in the subject. By the time they reached Cabo San Lucas, Gene was on the beach giving lectures to other boaters desirous of a celestial navigation refresher course. Bottom line: There is no shortage of books that purport to teach you the classic art of Celestial Navigation, but almost all fall short in one way: they lose you early on by using terms you’ve never heard of, assuming that you already have that knowledge. The writers of those books just don’t have the ability to ‘dumb things down’ to the level of absolute beginner. Gene Grossman solves that problem by assuming that you are a complete idiot, and talks down to you in such a simple way that you’re sure to understand everything simple step that he clearly explains. This is the perfect book for any boater interested in improving his or her navigational skills, and would like to look into proper use of the sextant to navigate around the world without depending on the reliability of several expensive electronic devices. There are no complicated drawings, no mathematical problems, no big astronomical words you’ve never heard of, and no reason to feel like the idiot you are with respect to celestial navigation. Reading this book is guaranteed to raise your level from ‘Idiot’ up to being merely ‘Navigationally Challenged,’ and will also suggest how to further elevate your status to that of Competent Navigator

Many books on celestial navigation take shortcuts in explaining concepts; incorrect diagrams and discussion are often used for the sake of moving the student along quickly. This book tells the true story-and the whole story. It conveys celestial navigation concepts clearly and in the shortest possible time.It's tailored for navigation in the GPS age-a time of computers, calculators, and web resources. Although it covers all of the traditional methods of 'working a sight, ' the primary thrust is using the (under $10) scientific calculator. By using equations that you key into your calculator, this book guides you toward a better understanding of the concepts of celestial navigation.You will learn novel ways to plot lines of position, ways to check your sextant accurately by star sights, and how to tell what time it is from a moon sight. The many appendices are a treasure of references and explanations of abstract ideas. Celestial Navigation is a crucial skill for the offshore navigator to know, this book provides the shortest path to that knowledge.

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 tables, with answers and explanations.

This book has been used for 30 years, updated periodically as needed. More than 20,000 students have successfully learned ocean navigation from these materials and gone on to cross oceans or circumnavigate the globe. This book covers how to find position at sea from timed sextant sights of the sun, moon, stars, and planets plus other routine and special procedures of safe, efficient offshore navigation. No previous navigation experience is required. The only math involved is arithmetic (adding and subtracting angles and times). This is a practical, how-to-do-it book, which also includes clear explanations of how it works and how to do it well. Plus this book includes other crucial factors of ocean navigation besides just finding out where you are from the stars, such as logbook procedures, dead reckoning, error analysis, route planning, and more. At the end of this book, you will be ready for ocean navigation. The book includes: text, practice problems, tables selections, detailed glossary, and full solutions. Printable work forms, plotting sheets, and other resources are available at no charge from www.starpath.com/celnavbook. Preface to the Second Edition: We are pleased to say that after ten more years of using this text we do not find reason to change the basic approach and methods of the teaching. We still use most of the same examples, which are now quite old, but that is the beauty of celestial navigation. It has not changed, so we do not benefit in any way from making all new examples, which would bring with them more chance of error in a book of many numbers. We have, however, notably improved and expanded the book. Each section has been updated and reformatted for a clearer presentation, often in response to student questions over the years. New graphics have been added and older ones all updated. There is much new content in the text, especially in the In-Depth chapter, including more detailed discussion of the sailings and more background on the principles. New sections were added on general ocean navigation and optimizing the fixes. We have also updated the electronic navigation section, as most ocean navigators will also be using other tools besides celestial.

Loran and GPS notwithstanding, there will always be a place for the sextant aboard any blue-water boat, if for no other reason than the thrill and mystery of finding one's position on earth by gazing at the heavens. Here is the indispensable reference that should accompany the instrument aboard. Cmdr. Bruce Bauer, a professional navigator and master mariner with the U.S. Merchant Marine, has distilled years of hands-on experience into an eminently readable guide to buying, adjusting, using, and repairing sextants. The Sextant Handbook is dedicated to the premise that electronic navigation devices, while too convenient to disregard, are too vulnerable to rely on exclusively. The book is designed to make beginner and expert alike conversant with this most beautiful and functional of the navigator's tools. Topics include: Assembly and Disassembly Vital Adjustments Avoiding Problems Rough Weather Sightings Oiling and Cleaning Immersion Baths Emergency Silvering Finding and Buying Used Sextants And Much More You'll also find a list of distributors, manufacturers, and dealers worldwide, a discussion of future trends, and numerous helpful hints, including sighting with eyeglasses and using a Rude starfinder. All in a thoroughly revised edition of a book acclaimed by navigation professionals.
