Description
Length arm: 38cm.Length base: 14cm. Used to plot position and course.
A nautical plotter typically consists of two straight edges, often called arms or rulers, joined by a pivot point. The rulers are usually transparent or translucent, allowing the navigator to see the chart beneath them. br>
To plot a course or position on a nautical chart using a plotter, the navigator places one ruler along the desired course line or bearing on the chart. The other ruler can then be moved along the chart to measure distances or plot additional lines, markings along the rulers to allow for easy measurement of distances on the chart. By aligning one ruler with the starting point and using the other ruler to measure along the chart, the navigator can determine the distance and bearing between two points.
Correct use of a plotter needs care and attention to detail to make sure plots and measurement are accurate.
