Plotting in restricted spaces can be accomplished easily with the Weems Compact Parallel Plotter. This 8.2-inch (20.8cm) rolling plotter is a smaller version of our popular 12-1/2 inch (31.75cm) Weems Parallel Plotter (#120). 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 for traditional parallel rules or triangles. The two rollers keep the plotter parallel to the chart as you slide it.
