You depart LAT 49°45.0'N, LONG 06°35.0'W, and steam 3599 miles on course 246.5°T. What is the longitude of your arrival by Mercator sailing?

Correct Answer: Option C — LONG 77°02.8'W

Applying Bowditch's Mercator sailing methodology, the difference of latitude and meridional difference are used to determine departure-to-arrival longitude offsets. Steaming $3599$ miles on course $246.5^\circ\text{T}$ from the initial position establishes the arrival longitude at $77^\circ02.8'\text{W}$.
