Description
The Weems & Plath Parallel Ruler 15″ (38.1 cm) in aluminum is a traditional and reliable navigation tool for manual course plotting and alignment on nautical charts. The parallel ruler consists of two transparent acrylic blades with *protractor scale*, connected by aluminum arms and polished aluminum handles that provide stable and smooth movement across the chart.
As you “walk” the ruler across the map, the hinges keep the angle constant so that courses and directions can be transferred precisely from one point to another. This makes the product particularly useful for traditional navigation, positioning work and teaching.
The Weems & Plath Parallel Ruler 15″ (38.1 cm) has a length that fits most charts and provides a good balance between reach and control. The transparent construction provides a good overview of chart details while working, while protecting the ruler from wear and tear during use.
This is a reliable and functional navigation tool that is suitable for both outdoor use, navigation courses and as a reliable tool on board. Weems & Plath is known for the quality and durability of its navigation instruments.
