Celestial for the Cruising Navigator ePub download

Merle B. Turner does an excellent job here. I particularly like the way Turner introduces you to Nautical Astronomy facts and fundamentals - this adds fascination to the subject.

Merle B. Have you ever opened an Elderidge Coastal Pilot and wondered why declination alone is given? Do you know about amplitudes and their uses at sea? Turner sheds more than a little light on these types of applications of celestial navigation. Finally, I have one complaint - minor, and one final area of praise. The complaint is that Turner occasionally assumes you know more than you do.

The American Practical Navigator (colloquially often referred to as Bowditch), originally written by Nathaniel Bowditch, is an encyclopedia of navigation. It serves as a valuable handbook on oceanography and meteorology, and contains useful tables and a maritime glossary. As of 2019 it is still published by the .

Merle Turner,Celestial Navigation for the Cruising Navigator - some theory. Alan Villiers, Cruise of the Conrad.

The book presents a comprehensive treatment of celestial navigation based upon the essential foundations of nautical astronomy and spherical trigonometry. Beginning with a discussion of position and time, it proceeds systematically to show how sextant observations coupled with time provide indispensable checks and information on course, distance, and position. Emphasizing computational rather than tabular solutions to sight reduction problems, while basic trigonometric formulae are developed, all computation is done with the most inexpensive hand calculator. The author also stresses the backgrounds of nautical astronomy, beyond the perfunctory routines of sight reduction. The reader, in other words, learns not only what, but why. While the treatment is directed toward the cruising sailor who wishes to plan and undertake oceanic voyages, it is sufficiently comprehensive to fulfill the needs of the professional mariner.

A great book for someone already very familiar with the popular method of celestial navigation - using Pub 249 and the Nautical Almanac. Mr. Turner promotes the use of the handheld calculator as an alternative to using the Pub 249. I enjoyed learning all the formulas and how to apply them to obtain solutions for much more than just a celestial navigation fix. I highly recommend the book for an advanced student of celestial navigation - something he himself says at the first of the book. Admittedly, this book is not for the novice. Regardless, it is a very good reference book. All that being said, there is an error in the book; either that or his description is poorly written. On page 153 he uses formula 8.11 to solve for a longitude from a Sun sight at time 0046 May 18. He combines this with a running latitude from a noon shot at 2205 May 17 for a running fix. His solution however is the longitude at 2205 May 17, not longitude at 0046 May 18 as he says. I think he may have used a wrong Hs which led him to the wrong longitude for 0046 May 18. Additionally, I appreciate he is trying to teach the use of the calculator, but it would have been much easier to use the GMT of his noon sight to figure his longitude straight up instead of the contortions on the calculator on a second shot. By using LAN (local apparent noon) there would have been no need to bother with the second shot at 0046 May 18 - perhaps negating his purpose of demonstrating a second observation. I would be happy to be corrected by anyone who differs with my opinion on this. Great book. I will carry it on board.

I regained an interest in navigation as a result of my desire to improve my ability to read technical material. I had graduated from Navy OCS in the mid 60's my initial exposure. My interest has been inspired by Patrick O'Brian novels.
I made little progress with celestial navigation by reading various editions of Duttons and Bowditch. Was surprised HO 214 was obsolete! Made tremendous progress using 'A Star to Steer Her By." But, came to the rapid conclusion that HO 229 sight reductions were tedious, slow, and error prone if you lack sleep or are under pressure. This is despite excellent tools such as the Davis workforms. Maybe Im just error prone!
Knowing that O'Brian era navigators and midshipmen did and learned navigation with use of only an almanac and logarithm tables? I looked for a method to do sight reductions using a scientific calculator. "Celestial for the Cruising Navigator" answers that need.
I also believe texts designed for amateurs (Sail Boat Types) should be enjoyable to read and be easily seen as being practical and useful to you. Merle B. Turner does an excellent job here.

Finally, I have one complaint - minor, and one final area of praise. The complaint is that Turner occasionally assumes you know more than you do. Keep Bowditch handy and it's no big deal. Finally, The book conveys a lot about the personality of its author. Turner is very intelligent, knowledgeable, occasionally likeably eccentric and entertaining. But, don't use this as your first celestial text. Start with something like "A Star to Steer Her By." This will boost your confidence, de-mystify the subject and whet your appetite for more. Collect a Bowditch and then read this text. The navigation space on a typical sailing cruiser is pretty cramped, the crew is limited, and you will come to appreciate the efficiancy using a calculator. Someday, GPS may fail you.

Probably one of the best, in depth, celestial navigation books out there. I wish it was available in electronic format.
