Celestial Navigation – Learn How to Master One of the Oldest Mariner`s Arts

Informative

I watched Tom's short video before I purchased the product. It is easy to understand and the book's illustrations make it easy to understand. I would recommend this for anyone interested in learning this.

I thought this book is pitched about right for someone who wants to learn celestial navigation from a practical perspective. The Air Sight Reduction tables are easy to use and Tom does a very good job of describing how to use them to get a position line.For those looking for more on the theory the book is bit light - no real mention of the PZX triangle and the fact that an altitude is not the zenith distance even though it is true altitude and calculated altitude that is used to find the position line intercept.Bit surprised to see diagrams with the zero meridian at the top of the page - this certainly is not the convention used when I was a deck officer in the Merchant Navy - zero was at the bottom so that west is on the left of the page.A really useful extra for the 'checking the compass section' would be the ABC Azimuth tables so that the user can then check the compass at any time - not just at sun rise or sun set.All in all a very good practical reference that I thoroughly enjoyed reading.

I felt that with this book and the various tables necessary I could sail round the world without a GPS and go by traditional methods. Tom Cunliff gives clear descriptions of how it all falls together without doing it in a complicated way. At the end you understand GHA and LHA as if you had done it all your life. Simply written and simply brilliant

as I expected & arived on time & in good condition thanks

This book is confusing if you haven't done the Theory course. However, once the theory is done, this serves as a useful summary / reminder of how to take the sights, prep the calculations and plot the position lines.

I did find the lack of page numbers in the Kindle version difficult to know where to look for drawings etc but as Tom explained in his email that the book was written many years ago and when it was put in electronic form the no provision for page numbers I did find the book very good thoughthank youK Gregory

This book is a great way to get to understand and use a sextant. Read the Kindle version on a 10" tablet or iPad for better clarity of the drawings and to be able to read the tables.

Thank you.

Concise, really really good illustrations. No wasted words Once you have this under your belt, go to Burch for a very detailed treatment, I did Google some terms where he wasn’t as detailed as I wanted, but you don’t need to do that to grasp the material. I’ve looked at older books by Kelch and Toghill but they lack the illustrations and detail. What I ended up doing was working from this book to Burch, back and forth. You certainly need Burch after this book, if you are going to take a test or actually navigated. Start here.

This book can't be bad. It's perfect and good explanation is there

Le tems veux ça ....il faut pas être pressé pour les livres...petit opuscule en offset couleurs avec des schémas élémentaires ...simple pour un début .

Es muy intuitivo y da una buena pauta de trabajo para posicionar te de forma rápida con el sextante nautico
