VEC Vectormaster

Given the position of a storm and the direction and speed of its advance, with the help of your Vectormaster, you can quickly determine a course that will put the maximum distance between your ship and an imminent storm. This circular rule provides the solution of time, speed and distance, fuel consumption, conversions, multiplication and division.

The face of the Vectormaster allows the rapid resolution of problems involving vectors, such as those encountered in the current sail, the determination of the direction and strength of the true wind, and the apparent wind to be expected on other items .
