About this item

  • Rotating Protractor


This is a Breton Plotter also known as a Portland Plotter or rotating protractor. It is used for chart navigation. Align the plotter between two points then rotate the centerpiece to align with the latitude and longitude lines and read the angle.

If you're looking for a Bretton plotter, this is a good one. It also has some additional navigation formulas screen printed on the surface, which are very helpful..

Flimsy but strong and durable for Being out in the desert, I love that It doesn’t have the twisty knob and can easily be moved from the center

Although not as best to use vs a Weems and Plath Protractor, it is great for travel as it is smaller and unbreakable.

This is a very convenient and practical tool, but don't forget to adjust for magnetic courses, because it is based on true magnetic projections.

Thin plastic that gets a myriad scratches and easily looses the printed lines. The only thing I like about the product is it's flexible nature. It would be nice to have this product built with better materials and a coating to prevent scratches.

Way too short given the size of nautical charts and the all black design makes reading difficult. Wonder whether people who designed this tool ever left their drawing board to step on a boat.

Four stars because it's difficult to spin the compass dial without moving the plotter. Add a couple of adhesive rubber feet and you've got a winner. :)
