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).
