Description
Excerpt from Maneuvering Board Manual
The ability of certain outstanding navigators and tacticians to rapidly and efficiently carry out missions, conduct scouting and search operations, and shift stations within a ?eet or other mobile unit has long been known. Although their skill has been described by such terms as having developed a good seaman's eye, basically their aptitude has been the result of being able to apply the principles of relative movement to the particular problem at hand. Relative movement is an everyday phenome non. The most familiar example of this is the apparent movement of celestial bodies across the sky. As the globe turns from the West to the East, to an observer stationed on the earth, the celestial bodies appear to rise in the East and set in the West. When two trains on adjacent tracks are moving in the same direction but at different speeds, to passengers on the faster train it appears that the slower train is moving backwards. By movement relative to the faster train and ignoring the actual direction and distance traveled over the face of the earth by both, that is what the slower train is doing.
The essential difference between the relative movement method of solving problems and the usual navigational plot method, is one of origins. The latter uses a point fixed with respect to the earth and called a Chart Point. The travel of units, portrayed by lines on the chart used, represents directions and distances actually traversed on the face of the earth' or over the ground. Such a diagram, when used in this publication, will be referred to as the Navigational Plot. The lines representing the travel of units over the ground in this diagram are called Chart Lines. When several units are being plotted on this diagram, their exact positions for any particular time must be carefully delineated before their positions relative to each other can be found. For a composite picture of the actions of several units, this is excellent; for planning actions in advance, the amount of trial and error involved usually causes much delay, so the relative movement method is to be pre ferred in most cases.
