Improve your understanding of charts and you will navigate with increased safety and confidence. First explaining how charts are compiled, this guides you through the elements that make up these vital navigational tools. In addition to the wealth of practical advice the book contains the Symbols and Abbreviations Used on Admiralty Charts in full.

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.

Designed for both land and water use, this comprehensive guide helps unlock the complexity of map and chart reading as it relates to navigation. Beginning with detailed technical descriptions of the tools of navigation—a compass, an altimeter, a GPS system, and a sextant—this handbook shows how to use these tools either individually or in combination with each other to navigate any area. Factors that cause tools and techniques to fail are discussed, such as why an altimeter often shows the wrong elevation, a GPS position is sometimes off track, and the sun often points in an unexpected direction. Twenty-one real-life scenarios provide practical wisdom for even the most intrepid navigator. Specific information on using the moon for directions and the stars for position, measuring boiling water temperature for elevation, map projections, map datums, great circle routes, and the UTM/UPS grid system is included.

A lot of people are drawn to the sea, and for good reason – it's the world's last wild and largely unspoilt wilderness. But to properly enjoy the sea, and to do so safely, you must have the skills, knowledge and confidence to plan thoroughly and stay one step ahead of the game. This book is thoughtfully written to help yachtsmen do just that. It's not another RYA Course Handbook; it's written by a mariner for other mariners. It's well-informed, easy to read and honest about the author's triumphs and disasters over a lifetime's navigating. He has a unique perspective having navigated in many parts of the world from high up on the bridge of a warship, close to the water in a cruising yacht and at depth in a submarine. After his navy career he was Chief Executive of the Royal National Lifeboat Institution (RNLI), often dealing with the consequences of poor navigation. The author brings the subject to life in a book that is designed to help yachtsmen refresh their knowledge of, and their enthusiasm for, the timeless skills of navigation. It is packed with hundreds of illustrations – colour photographs, charts, diagrams and tables – making the text easy to understand. The book is part of Fernhurst Books' Skipper's Library series of practical books for the cruising sailor.

What if you could take a voyage with an ancient mariner and have him teach you the navigation skills he has acquired over a lifetime of sailing? Now you can. Come along with Nick de Munnik as he explains basic navigation fundamentals and shows you how to use them for coastal, electronic and celestial navigation.The author's conversational and easy to understand descriptions include extensive diagrams and examples, making all aspects of boat navigation seem intuitive. This book is a 'must have' for the new boater and a great reference for the seasoned sailer.Building on the navigational skills covered in the coastal and electronic navigation sections, the celestial navigation section is second to none. Nick developed this for his celestial navigation courses and it continues to be used as class materials in celestial navigation courses today.

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.

A guide to tuning the sails and rigs of yachts and small keelboats, featuring step-by-step instructions and more than 150 illustrations.
