Question

A vessel at LAT 40&deg;42.0'N, LONG 74&deg;01.0'W, heads for a destination at LAT 14&deg;41.0'N, LONG 17&deg;26.0'W. Determine the true course and distance by Mercator sailing.

Accepted Answer

Option A: 118&deg;T, 3365.0 miles. Mercator sailing is the standard method for determining rhumb line tracks. By calculating the difference in latitude and the difference in meridional parts between the departure and arrival points, the course is found to be 118°T and the distance 3365.0 miles, as verified by standard navigational tables.
