Summary

This volume of the Admiralty Manual of Navigation describes off-shore navigation - the safe conduct of a ship across the open sea where, in general, hearings of objects on land cannot be obtained except by means of radio waves (i.e. using radio fixing aids). The first chapters are mainly concerned with distances, courses, tracks and charts; then various methods of obtaining position lines and positions from astronomical observations are explained, including a rapid. method in the last chapter.
The volume also contains an outline of meteorrology and weather forecasting.
