Correction for the magnetic variation from the compass rose. The answer is 6.75 deg, E or 6.8 deg.E, not 4.75 deg E.
In this comprehensive tutorial, we're diving into the essential skill of determining magnetic variation using both a compass rose and an Electronic Chart Display and Information System (ECDIS). Understanding magnetic variation is crucial for safe and accurate navigation, whether you're a seasoned mariner, a budding sailor, or a maritime student.

Magnetic variation, also known as magnetic declination or compass variation, is the angle between the true north direction (geographic north) and the magnetic north direction indicated by a compass at a specific location on the Earth's surface.
