As paper navigational charts are replaced by vector images on computer screens, magnetic compasses enhanced by digital flux gate technology, and chronometers joined by atomic clocks, the demand has been mounting for an extensive update to the classic reference known worldwide as Dutton's. To meet the varied needs of today's recreational, naval, and commercial navigators the Naval Institute introduces this new edition of a guide that has remained the seafarers choice for more than three-quarters of a century. It blends the traditional navigation techniques first compiled by Benjamin Dutton in 1926 with technological marvels of the twenty-first century to authoritatively cover all phases of surface navigation. For example, while the book acknowledges that many navigators still peer into the skies through sextant telescopes, it also helps them take full advantage of man-made Global Positioning System (GPS) satellites. Valued as both an indispensable quick reference and a comprehensive text, Dutton's makes accessible such foreboding subjects as spherical trigonometry through the use of step-by-step explanations and examples that encourage practical use. To insure accuracy and relevancy, a board of experts made up of naval and Coast Guard officers, merchant mariners, accredited harbor pilots, and sea-service academy professors, has carefully reviewed this fifteenth edition. The result is an unparalleled treatment of the art and science of nautical navigation that both amateur and veteran navigators will use to safely navigate the waters of the world.
