The Complete On-Board Celestial Navigator

The Complete On-Board Celestial Navigator


Once the universal system of navigation out of sight of land, celestial navigation is now more often a backup to electronic navigation methods, chief among them the Global Positioning System (GPS). However, among cruising sailors the use of a sextant to locate one's position on the ocean is still a skill treated with pride and respect. U.S. Power Squadron courses in celestial navigation remain popular for this reason, and because it's wise to have a backup method of navigation if your GPS receiver malfunctions. The Complete On-Board Celestial Navigator responds to these realities with the ideal package for today's market. Traditionally, the navigator would learn sight-taking skills from an instructional book; identify stars or planets for "shooting" sights using a graphic or tabular star finder; obtain the precise position in the heaven of the chosen star, planet, moon, or sun at the time of the shooting from an annual nautical almanac; and "reduce" the sextant sighting using sight reduction tables. All these components together add up to an unwielding package.



Celestial Navigation in a Nutshell by Hewitt Schlereth


From Book News, Inc.
In this guide, Schlereth draws on his experience as a sailor to explain 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 book offers instruction on how to take sights by the sun, moon, stars and planets, and discusses the advantages and disadvantages of each method. Common errors are reviewed, and suggestions given for improving accuracy. Several examples and situational illustrations are included. No bibliography.Book News, Inc.®, Portland, OR
