A vessel at LAT 45°36.0'N, LONG 11°36.0'W, heads for a destination at LAT 24°16.0'N, LONG 73°52.0'W. Determine the true course and distance by Mercator sailing.

Correct Answer: Option D — 247°T, 3299.3 miles

Navigational triangle resolution via Mercator sailing principles accounts for the earth's expansion on flat charts. Using meridional parts difference and longitude difference per Bowditch formulas accurately resolves the rhumb line track to course 247°T and distance 3299.3 miles.
