A vessel at LAT 32°14.7'N, LONG 66°28.9'W, heads for a destination at LAT 36°58.7'N, LONG 75°42.2'W. Determine the true course by Mercator sailing.

Correct Answer: Option C — 301.8°T

Applying Mercator sailing principles, the difference in latitude and meridional parts are calculated to determine the course angle. The formula tan(C) = DLo / DMP yields a course of 301.8°T. This method accounts for the convergence of meridians, ensuring accuracy over long distances as defined in Bowditch.
