Our parallel rules are made by Weems & Plath, one of the most respected brands in the navigational instruments business. These respectable 24″ rules (610 mm) will leave you smug as you draw lines that your classmates could only dream of. They are great for the classroom, easy to carry around and equally at home in the chartroom or on the bridge.

Navigational equipment should always be top quality, and we can say beyond all doubt that Weems & Plath have got it right. The blades are a strong, sturdy acrylic with bevelled edges. The knobs, pivot pins and link bars are aluminium, with cork feet to ensure no slipping and sliding.

Weems & Plath supply many of the major chart agents, which means these rules are in daily use on merchant ships around the world. If that’s not a stamp of approval, we don’t know what is!
