It is essential for commercial skippers\/superyacht captains to know and is also helpful for those taking the RYA Ocean Yachtmaster™ exam. The author breaks down the process step-by-step, providing context and memorable information, and includes troubleshooting tips and time-tested 'proformas' to aid in putting the theory into practice on board. \u003c\/blockquote\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\\n                                                            \u003cstrong\u003eFormat\u003c\/strong\u003e: Hardback\u003cbr\u003e\\n                              \u003cstrong\u003eLength\u003c\/strong\u003e: 160 pages\u003cbr\u003e\\n                              \u003cstrong\u003ePublication date\u003c\/strong\u003e: 14 October 2021\u003cbr\u003e\\n                              \u003cstrong\u003ePublisher\u003c\/strong\u003e: Bloomsbury Publishing PLC\u003cbr\u003e\\n                          \u003c\/p\u003e\u003cp\u003e\u003cbr\u003eThe 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 traveling 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 backup 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 Yachtmaster™ 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.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cp\u003eDid you know that a person standing on the equator is effectively traveling at 900mph?
