Marine parallel ruler is made of transparent acrylic with aluminum arms.
A marine parallel ruler is a navigation tool used by sailors and navigators to plot and measure courses on nautical charts. Its unique design allows you to draw parallel lines with ease, which is essential for accurate chart navigation at sea.

1.It is made from transparent acrylic which allows navigators to see through the ruler and view the chart beneath clearly.
2.The ruler consists of two straight arms joined by pivots. These arms remain parallel to each other when adjusted, allowing them to maintain a constant distance apart.
3.The pivots between the arms allow the ruler to be adjusted to different distances, accommodating various scales on nautical charts.
4.Have non-slip cork pads to ensure stability on the chart and prevent accidental movement while plotting.

1.It is a reliable method for manual chart plotting and navigation, serving as a backup in case electronic navigation systems are unavailable.
2.It is lightweight and compact design that make it easy to store and carry aboard ships and boats, ready for use whenever needed.

The marine parallel ruler remains an essential tool for navigators, ensuring accurate and reliable navigation through proper chart plotting, measurement, and course planning techniques.
It is also a valuable tool in maritime training and education, helping students and sailors learn essential navigation skills, chart reading, and plotting techniques.
