Astro Navigation Demystified
Jack Case is a retired naval officer and experienced navigator who became a teacher when he left the sea.  He taught navigation not only to sailors but also to students of mathematics and geography and was able to demonstrate the important links between these subjects.  Over many years, he developed the art of teaching navigation in an interesting way so that it could be understood by students of all ages.  Many of the author's adult students, including small boat owners and yachtsmen, expressed the need for an easily read and un-complicated book to help them to understand astro navigation. Hence the reason for writing this book.
