by Blewitt, Mary, revised by Andy Du Port

CAD $23.00

13th ed. Since this book was first published more than six decades ago, advances in electronic navigation have moved most offshore navigators to adopt press-button convenience. But traditional skills are still invaluable when things go wrong: batteries fail, aerials go overboard, electronics get wet. This guide’s simple approach to celestial navigation–the worked examples require only addition and subtraction–explains its reputation and longevity.
