Weems & Plath 12" Parallel Rule
Perfect for Small Craft Charts
This sturdy 12-inch (30.48cm) parallel rule with brushed aluminium arms is a reliable tool for plotting courses and measuring distances on nautical charts. It features an integrated protractor scale, allowing you to measure angles and bearings from any convenient meridian or compass rose.
This parallel rule is comprised of two straight edges joined by hinges, allowing them to move closer or further apart while remaining parallel. By carefully moving the rule across the chart and securely holding down the non-moving edge, you can effectively plot a course or transfer bearings with accuracy.
Features:
- 12-inch (30.48cm) length
- Brushed aluminium arms
- Polished aluminium handles
- Milled acrylic with bevelled edges
- Integrated protractor scale (Captain Fields Pattern)
- Protective plastic sleeve
- Limited Lifetime Warranty
How to Use a Parallel Rule
Place one edge of the parallel rule along your desired course or bearing on the chart. Hold this edge securely while carefully moving the other edge to a new position on the chart. This allows you to transfer lines and angles accurately, making it an essential tool for navigation and chartwork.
A History of Precision
Parallel rules have been used by navigators for centuries to draw parallel lines on charts. The earliest versions date back to the 16th century, and the design was further refined in the 19th century by Captain William Andrew Field, who added a protractor scale and compass points for easier bearing measurement.
