With the Weems Compact Parallel Plotter you can do parallel plotting easily in restricted spaces. This parallel plotter is a smaller version of our traditional rolling plotter. It is mounted on an aluminum roller assembly that allows you to plot courses and parallel lines by simple direct transfer without the space required of traditional parallel rules or triangles. The two rollers keep the plotter parallel to the chart as you slide it.
