In fact, there are no pre-requisites for using this book - the readers are only expected to be able to read, add/subtract, understand the angles and know how to use the protractor. Al sailors will for sure enjoy this volume, regardless of their experience - the content of this classic book will definitely be equally useful and interesting to everyone from armchair-navigators to the racers and circumnavigators.

Any kind of boating can be fun, the author points out, racing around the marks, or coastwise cruising where there is almost always at hand visual reference ashore from which bearings can be taken for locating ones position and thus finding ones way home. Author:, Date: 01 Dec 2010, Views: Celestial Navigation by H. 249 Schiffer Publishing (April 1975) ISBN: 0870331914 111 pages File type: PDF 51 mb. Sailors, from the most serious of circumnavigators and racers, to the armchair-navigator will enjoy this classic on celestial navigation.

John Karl's book lets the reader proceed in this way. A line of position is put on a chart after only 40 pages. But then he will take you further in understanding the science and art of celestial navigation than any other book I have seen. Celestial Navigation in the GPS Age is a mixture of history, math, and rational explanations that the reader may sample as desired. This may not be the only book to which you are exposed in learning celestial navigation, but it certainly should be one of them

"Any kind of boating can be fun," the author points out, "racing around the marks, or coastwise cruising where there is almost always at hand visual reference ashore from which bearings can be taken for locating one's position and thus finding one's way home. Severing these ties with land, however, offers a new kind of fun, a new kind of freedom, a freedom from dependence on land." Here is a basic beginner's book, introducing the amateur to the tools, the vocabulary, and the techniques of celestial navigation. Among the recommended tools are the H. O. 249 tables, the most widely used among amateur navigators at sea because of their simplicity. The ability to determine one's position at sea both liberates the sailor from the land and enables him to find his way to his destination. If you can read, add and subtract, understand angles, and use a protractor, you can learn to navigate in your armchair or at sea from Celestial Navigation by H. O. 249.

Enough information to sail anywhere in the world without a GPS.
Hi_Jacker
Milligan lays out the process for you, but does very little in explaining what is going on within the process.
He pools a LOP right in with the noon shot. I didn't like that, The book draws no line between the noon shot, and determination of LP's and the the use of sight red. tables. He doesn't make it clear that you don't need S.R. tables when you do a noon shot.
I found myself asking when will I use these S.R. tables during the noon shot. He leaves out details when it comes to teaching the inexperinced.
