Emergency Navigation: Find Your Position and Shape Your Course at Sea Even If Your Instruments Fail 2nd Edition by David Burch
Requirements: PDF Reader, 5.5 mb
Overview: 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–from the ancient skills of Polynesian navigators to the contrails of airliners overhead–to calculate speed, direction, latitude, and longitude and to perform all aspects of piloting and dead reckoning.
