Parallel Rules - Sailing (gambling)


A navigational tool used to move a line on a chart from one location to another without changing its angle, such as when moving a plotted course to a compass rose. Parallel rules are two straight edges that are mechanically connected such that both edges always remain parallel. Lines can then be "walked" across a flat chart.
