The Marine Sextant
The marine sextants only function is to measure angles, either
horizontally or vertically. The most common use of the sextant is for
celestial observations using vertical angles between celestial objects and
the horizon. It is also used for fixing your position using horizontal
angles between three charted objects. In this chapter, we will concern
ourselves with the latter method. Before we can learn how to fix the
ships position using the marine sextant, we need to learn how to operate
the marine sextant. Figure 8-12 shows the parts of a marine sextant.
