Etymology: "Chartplotters" is the plural of "chartplotter," a noun for a marine navigation device that displays a vessel's position on an electronic chart. The word is a compound of "chart," a map used for navigation, and "plotter," a device or person that marks points or lines on a map, from the verb "plot," meaning to mark out a course or position. Joined together, the two parts describe a device that plots a course over a chart, so the term's meaning is transparent from its components.
