The Weems & Plath Compact Parallel Plotter, as the name would suggest, allows you to parallel plot easily even when in restricted spaces. The Weems plotter comes with a semi circular protractor and contains distance scales at 1:20,000, 1:40,000 and 1:80,000 to fit N.O.S. Coast and Harbor Charts, along with an inch scale.

A smaller version of the more traditional rolling plotter, it is mounted on an aluminium roller assembly that gives you the freedom to plot courses and parallel lines by simple direct transfer, and without needing the space of traditional parallel rules or triangles.

  • Dimensions: 89mm x 318mm
  • Weight: 141g
  • Distance scales at 1:20,000, 1:40,000 and 1:80,000
  • Fits N.O.S. Coast and Harbor Charts, as well as an inch scale
  • Semi-circular protractor to plot courses against a meridian
  • Durable acrylic construction
  • Lifetime Warranty
