Any kind of boating can be fun, the author points out, racing around the marks, or coastwise cruising where there is almost always at hand visual reference ashore from which bearings can be taken for locating ones position and thus finding ones way home. Severing these ties with land, however, offers a new kind of fun, a new kind of freedom, a freedom from dependence on land. Here is a basic beginners book, introducing the amateur to the tools, the vocabulary, and the techniques of celestial navigation. Among the recommended tools are the H. O. 249 tables, the most widely used among amateur navigators at sea because of their simplicity. The ability to determine ones position at sea both liberates the sailor from the land and enables him to find his way to his destination. If you can read, add and subtract, understand angles, and use a protractor, you can learn to navigate in your armchair or at sea from Celestial Navigation by H. O. 249.
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.
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.
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. 'The "bible" of navigation for generations of yachtsmen... worth its weight in gold' Sailing
Learn—and Appreciate—What Master Navigators Have Practiced for Centuries in This Hands-on, Friendly Approach. Celestial navigation, in all its forms, is nearly as old as mankind. Anyone who can master its intricacies stands at the end of a long line of master navigators that is centuries old—an expert among many who would be lost with electronics. David Berson, a columnist for Ocean Navigator magazine and an instructor at both the Ocean Navigator School of Seamanship and onboard the training schooner Ocean Star, offers here an approach that is refreshing, unique, and sure to attract a new generation of readers looking to demystify this essential art for sailors. Through his hands-on coursework Berson has developed a practical and learnable method of teaching that has appealed to a new generation of students. He will share his proven method here for the first time. While many books on celestial navigation insist this age-old art is needed only when electronics fail, Berson uses a unique approach that allows boaters to combine both the modern and the traditional. No other books does that. In Celestial Navigation, as he does in his popular column and classes, Berson simplifies the math that so often frightens and deters potential students. Berson takes the same approach with his writing that he does with his classes and columns,informal true-life anecdotes that entertain as well as educate. To Berson, celestial navigation is personal and valuable. Anyone reading this book will catch his contagious enthusiasm.
