Find your way on the water, even when your equipment is down
As complex electronics have come to dominate boat navigation, "Emergency Navigation" provides an essential backup for every ocean mariner. David Burch shows you how to find your position and plot a course to safety--even if your navigation equipment is damaged or lost--using ancient and modern skills or rudimentary materials like a stick, a piece of string or a pair of sunglasses. New edition includes new navigation methods, enhanced graphics and updated resource lists.
