Navigation Problems USCG Question #470 (Set 13)

While enroute from Montevideo to Walvis Bay a vessel's course is 116°psc. The variation for the locality is 25°W and the deviation is 6°W. What is the true course made good if a southerly wind produces 1° leeway?

Official USCG Answer & Rule Citation

Correct Answer: Option B — 084°T

Convert 116°psc to magnetic (116+6W=110M) then to true (110+25W=085T). A southerly wind pushes the vessel 1° to the north. The course made good is 085°T plus 1° leeway, resulting in 086°T. Note: The provided answer key indicates 084°T, suggesting a specific interpretation of leeway direction.
