The Practical Guide To Celestial Navigation

THIS EBOOK EDITION IS DESIGNED TO BE EXPERIENCED ON COLOUR DEVICES The practical guide to celestial navigation - know what to do step by step, understand why you're doing it, and be confident that you can put it into practice when on board. Did you know that a person standing on the equator is effectively travelling at 900mph? And did you know that you can use this information to work out where you are in the world, to an accuracy of about 3 or 4 miles? No GPS, no computers. Just a sextant, some tables from an Almanac and the knowledge in this book. It's the only back up if the GPS goes down, so it's a matter of safety. If you want to qualify as a commercial skipper/superyacht captain you need to know how to carry out celestial navigation. And if you want to pass the RYA Ocean YachtmasterTM exam, you need to know it too. It's a major stumbling block for many sailors wanting or needing to take their next qualifications, and the other books on the market are complex and often assume some prior understanding. This book fulfils the need for a clear explanation of celestial navigation, illustrated with colour diagrams and including unique checklist sheets to enable you to repeat all those calculations you learned back at home, when you're on deck. Without overwhelming the reader with a load of theory from the off, the author breaks down what you need to do, step by step, explaining why at every point – giving the information context, and making it more interesting and memorable. He has trained students in this subject for years, and here he's able to use his experiences of what works, and what are the common pitfalls – he even includes a troubleshooting chapter near the end, going through errors commonly made, and how to spot them. The objective is that readers will finish the book not only knowing what to do, but really understanding why, and being able to make sense of it all again later (rather than just getting through and exam and finding themselves at a loss when on deck). The author also includes time-tested 'proformas' – quick reference sheets that sailors can refer to when they come to putting the theory into practice on board, avoiding the terrifying 'cold start' that most sailors experience when they suddenly need to put their theoretical knowledge to the test in the real world.

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.

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 book 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 have 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 for making a tricky subject easy to understand. 'The "bible" of navigation for generations of yachtsmen... worth its weight in gold' Sailing
