Junior Navigation is the first of a two-part program of study in offshore (open ocean) navigation.  It is designed as a practical, how-to course, leaving the theoretical and more advanced techniques for the Navigation Course.  Subject matter includes: basic concepts of celestial navigation, how to use the mariner's sextant to take sights of the sun, moon, planets and stars, the importance and techniques of accurate time determination, use of the Nautical Almanac, how to reduce sights to establish lines of position (LOPs), and the use of special charts, plotting sheets and other navigational data for offshore positioning and passage planning.
