About the Author
David Burch is the founder and president of the Starpath School of Navigation and the author of nine books on navigation. Burch has more than 70,000 miles of ocean sailing experience, ranging from the Arctic to Tahiti. He has sailed across the Pacific twelve times and has received the Institute of Navigation's Superior Achievement Award for outstanding performance as a practicing navigator.
Every sailor knows that instruments can fail. Things get wet, break, fall overboard. Whether you're safe on your boat or drifting in a life raft, let David Burch show you how to find your way no matter what navigational equipment you have.
Often relying on common materials like a small stick, a plastic bottle, even a pair of sunglasses, Burch explains how to make use of all available means梖rom the acient skills of Polynesian navigators to the contrails of airliners overhead梩o calculate speed, direction, latitude, and longitude and to perform all aspects of piloting and dead reckoning.
