While electronic navigation is here to stay, author Bob Sweet recognizes that they are still based on traditional charts and piloting skills, and he combines the two to pass along to you a solid understanding of all the principles of marine navigation. In addition to its continued ground-breaking instruction for the now-digital process of navigation on board power- and sailboats, Sweet helps you understand recent options for chartplotters, less expensive handheld GPS units, smart phones, and the navigation possibilities presented by phone apps. New to this edition is a section entitled "Ooops," which provides an insightful collection of boating accident tales resulting from common GPS and chartplotters no-nos. Using The Weekend Navigator, you can get on the water right away and learn to navigate in an afternoon with GPS; master chart-and-compass piloting while, not before, he or she departs; plot courses and fix positions on paper or electronic charts; and more.
