The Weems and Plath 15 inch Parallel Ruler is a very effective navigation tool which has been assembled using high-quality solid brass arms and handles which adds a traditional elegance as well as durability to a practical piece of a vessel’s navigation equipment.
Made to last in extra-strong, crystal-clear acrylic, the Weems and Plath 15 inch Parallel Ruler backs that up by carrying a Weems and Plath lifetime warranty.
Parallel rulers are used by navigators to plot direction on a nautical chart. They are, essentially, 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 rulers about the chart while still maintaining the same angle.
