Your vessel is steering course 166°psc, variation for the area is 8°W, and deviation is 3°W. The wind is from the west-southwest, producing a 2° leeway. What true course are you making good?

Correct Answer: Option C — 153°T

Convert compass course to true by applying variation and deviation (166° + 8°W + 3°W = 155°T). Leeway is the drift caused by wind; with wind from the WSW, the vessel is pushed to the east (starboard), requiring a 2° correction to the left, resulting in 153°T.
