Weems & Plath Deluxe Parallel Rule
An essential item in any proper navigation kit, the aluminum parallel ruler is used to plot direction on your nautical chart. The aluminum parallel ruler is, essentially, comprised of two straight-edges hinged so that they maintain the same angle. By alternating the moving edge, and securely holding down the non-moving edge, you can move the aluminum parallel ruler about the chart while still maintaining the same angle. Includes protractor markings.
