Your course to steer and speed over the ground are calculated instantly.
Enter magnetic variation and deviation and your course to steer is converted from True to Magnetic to Compass bearing.
Correct for Leeway, simply enter the wind direction and the course to steer will be corrected to counteract the wind.
