Parallel Rulers 18"

The 18-inch (45.72cm) Aluminum Arms Parallel Rule feature aluminum arms that join two clear acrylic rulers inscribed with a protractor scale. An essential item in any proper navigation kit, these rules are used to plot direction on a nautical chart from any convenient meridian or compass rose. The two straight-edged rules are connected to maintain the same angle. By walking the rules across the chart and securely holding down the non-moving rule, you can effectively plot a course.
