In this easy-to-use guide, Hewitt Schlereth explains clearly and concisely how to navigate any stretch of sea using only a hand-held sextant, a watch, a plotting sheet and a copy of the Nautical Almanac. The basic process is simple: take a sight with a sextant, establish a secondary reference or benchmark sight, compare the two sights and plot the result of the comparison on a chart. Schlereth demonstrates how to take sights by the sun, moon, stars and planets, discussing the advantages and disadvantages of each method. The reader is taken carefully through several examples and situational illustrations, making this a most effective self-teaching guide.
