Description
The Weems & Plath Parallel Ruler 18″ (45.7 cm) is a timeless navigation tool designed for accurate course plotting and alignment on nautical charts. This model features robust aluminum frames that hold together two transparent rulers with a built-in degree scale, allowing the rulers to be moved across the map without changing the angle.
By holding one ruler firmly and moving the other in parallel, courses and directions can be transferred precisely from one point to another on the map. The transparent design provides a good overview of map details during work and contributes to high accuracy.
The parallel ruler is well suited for navigation courses, maritime education and professional chart work, as well as for recreational boaters who want to master traditional navigation. Weems & Plath is known for the high quality and longevity of its navigation instruments.
