This guide to celestial navigation covers the instruments required, estimating positioning and dead reckoning, tables and computations, course plotting and star identification. It concentrates on the plotting of the boat's position by sun, planets and stars when out of sight of land.
This was a decent book to learn the basics of celestial navigation. It went into detail on the use of the sextant, which was the most valuable section, as I used the instructions that came with my Mark 3 sextant to get through it. There are also chapters on dead reckoning, the celestial globe and star identification. Other valuable chapters included information on the sight reduction tables and use of the Nautical Almanac. Very dry, but highly instructive and in no way a waste of time and money. I am interested in comparing it to Practical Celestial Navigation, by Susan Peterson Howell.
