Your vessel receives a distress call from a vessel reporting her position as LAT 35°01'S, LONG 18°51'W. Your position is LAT 30°18'S, LONG 21°42'W. Determine the true course from your vessel to the vessel in distress by Mercator sailing.

Question

Your vessel receives a distress call from a vessel reporting her position as LAT 35&deg;01'S, LONG 18&deg;51'W. Your position is LAT 30&deg;18'S, LONG 21&deg;42'W. Determine the true course from your vessel to the vessel in distress by Mercator sailing.

Accepted Answer

Option C: 153&deg;T. Mercator sailing employs the difference in meridional parts (m) to determine the course angle. Using the formula tan(Course) = DLo / m, where m is the difference between meridional parts of the two latitudes, the calculation results in a true course of 153°T, adhering to standard rhumb line navigation principles.
