Year: 2021 Language: english Author: Phil Somerville Genre: Guide Publisher: Bloomsbury Publishing Edition: 1st ISBN: 1472987586 Format: EPUB/PDF/AWZ Quality: Unknown Pages count: Multiple (252 pages for .pdf) Description: 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. It's the only back up if the GPS goes down, so it's a matter of safety. So 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 jargon-free 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. 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.
