A vessel at LAT 32°05.0'N, LONG 81°06.0'W, heads for a destination at LAT 35°57.0'N, LONG 5°45.0'W. Determine the distance by Mercator sailing.

Correct Answer: Option D — 3770.6 miles

Mercator sailing utilizes the difference in latitude and the difference in meridional parts to find the course and distance. Calculating the meridional parts for both latitudes and the difference in longitude, the distance is determined by the formula: Distance = (DLat) / cos(Course). This results in 3770.6 miles.
