The Weems Parallel Plotter is our most popular rolling plotter. It is mounted on an aluminium roller assembly that allows you to plot courses & parallel lines with simple direct transfer & doesn’t require the space that traditional parallel rules or triangles need. The roller keeps the plotter parallel as you slide it across the chart. 

It includes distance scales at 1:20,000, 1:40,000 and 1:80,000 as well as an inch scale. A semi-circular protractor for measuring course & bearing against meridian on a chart & two quarter circle protractors for measuring course & bearing against parallel of latitude are built into the plotter. It is also used for measuring or laying off courses & distances on a nautical chart.
