This book is ground breaking not because of what it has, but what it doesn't have: No complicated drawings; no mathematics problems; no astronomical talk; no big words you've never heard of. Sailor-author Gene Grossman finally breaks this wonderful subject down into plain English and explains it in such a way that you will no longer have any excuse to claim that you know nothing about the valuable boater's subject of Celestial Navigation. This book was inspired by Gene's DVD program of the same title, which has gained worldwide popularity and is being used the the Navy, Coast Guard and sailing schools all over the world.
