This circular slide rule provides for the solution of time, speed and distance, fuel consumption, conversions, multiplication, and division. The face of the Vectormaster permits the rapid solution of problems involving vectors, such as those encountered in current sailing, determination of true wind direction and force, and apparent wind to be expected on other headings. Given the position of a storm and direction and speed of its advance, with the aid of your Vectormaster you may quickly determine a course which will put maximum distance between your vessel and an oncoming storm. Vectormaster instruction booklet included.

      Wonderfully failsafe low tech navigation tool. When your plotter fails you need this in the chart table.
