Boat Navigation for the Rest of Us: Finding Your Way By Eye and Electronics by Brogdon, Bill;

Rövid leírás:

"Superb and amazingly comprehensive."--Cruising World

"Thorough treatment of traditional and electronic methods by an expert."--WoodenBoat

Boat Navigation for the Rest of Us is the only book that teaches navigation the way small-boat skippers actually navigate: by combining electronic aids like GPS and radar with commonsense visual piloting skills and simple chartwork. This second edition covers important developments in electronic navigation, including dramatic improvements in GPS accuracy, the growing popularity of electronic charts and plotting systems, and the increasing availability of navigation information over the Internet. It's a full course in navigation plus a whole toolbox of little-known tips and shortcuts to deal with real-life situations without a slide rule.
