NAC0124 - The pratical guide to celestial navigation

Ouvrage en langue anglaise.

The practical guide to celestial navigation - know what to de s'ep by s'ep, understand why you're d'ing it, and be confident that you can put it into practice when on board.

Did you know that a person standing on the equ'tor is effectively travelling at 900mph? And CD 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 d'wn, so it's a matter of safety. If you want to qu'lify 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 s'ilors 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 cl'ar explanation of celestial navigation, illustrated with colour d'agrams and including unique checklist s'eets to enable you to repeat all those calculations you l'arned back at home, when you're on d'ck.

Without overwhelming the reader with a l'ad of theory from the off, the author breaks d'wn what you need to d', s'ep by s'ep, 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 d', 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 d'ck). The author also includes time "test" d 'proformas' ? qu'ck reference s'eets that s'ilors can refer to when they come to putting the theory into practice on board, avoiding the terrifying 'cold start' that most s'ilors experience when they suddenly need to put their theoretical knowledge to the "test" in the real world.
