Your vessel is steering course 149°psc, variation for the area is 13°E, and deviation is 4°E. The wind is from the northeast, producing a 4° leeway. What true course are you making good?

Correct Answer: Option A — 170°T

Convert compass to true: 149°psc + 4°E (Dev) = 153°M. 153°M + 13°E (Var) = 166°T. A northeast wind pushes the vessel to the southwest, requiring a 4° leeway correction to the northeast. Adding 4° to 166°T results in a true course made good of 170°T.
