Your vessel is steering course 216° per standard magnetic compass, variation for the area is 9°W, and deviation is 2°E. The wind is from the east, producing a 5° leeway. What true course are you making good?

Question

Your vessel is steering course 216&deg; per standard magnetic compass, variation for the area is 9&deg;W, and deviation is 2&deg;E. The wind is from the east, producing a 5&deg; leeway. What true course are you making good?

Accepted Answer

Option B: 214&deg;T. Applying compass corrections per Bowditch: Compass 216° plus 2° East deviation gives magnetic 218°, minus 9° West variation yields true 209°. An easterly wind sets the vessel to the west, adding 5° leeway to port for a resulting true course made good of 214°T.
