Description
The Nautical Parallel Ruler is used on paper charts to transfer directions while maintaining parallel alignment between chart references.

Transparent acrylic and metal-edged models support clear chart visibility and repeated bridge use. Ruler length, hinge construction, edge graduation, roller option, material and storage sleeve should be selected according to chart-table size and navigation practice.
