The Parallel Ruler is an essential navigation instrument used for accurately plotting courses and transferring bearings on nautical charts. It consists of two straightedges connected by hinged arms, allowing movement while maintaining a constant angle.
This tool enables navigators to transfer course lines from the compass rose to different areas of the chart with precision. By "walking" the ruler across the chart, the user can maintain the exact angle needed for accurate navigation planning.
Manufactured from durable materials with metal linkages, it ensures stability, longevity, and reliable performance. Suitable for professional mariners, sailors, and navigation enthusiasts using traditional chart navigation methods.
