Integral Ruler

Unmatched Precision for Modern Navigation
The Integral Navigation Ruler is more than just a plotting tool—it’s a game-changer for sailors who refuse to compromise on accuracy. By merging the time-tested Jean Cras ruler with an integrated TOPO protractor, this ruler eliminates the need for multiple tools, streamlining your workflow while delivering unparalleled precision. Its rotating window, a standout feature, ensures that your route readings remain straight and clear, even when plotting courses in the southern hemisphere, where traditional rulers often fall short.

Designed for Real-World Conditions
Navigating with paper charts demands tools that can keep up with the challenges of the marine environment. The Integral Navigation Ruler rises to the occasion with its exclusive yellow flat surface, which dramatically improves visibility against the often cluttered and colorful backgrounds of nautical charts. The red and black engravings—specifically for angles between 180° and 360°—are not just for aesthetics; they’re strategically placed to reduce errors and speed up your plotting process. Crafted from high-quality 1 mm thick PVC, this ruler strikes the perfect balance between durability and lightweight handling, ensuring it won’t weigh down your navigation station.
