Question

Your vessel is steering course 299&deg;psc, variation for the area is 7&deg;W, and deviation is 4&deg;W. The wind is from the southwest, producing a 3&deg; leeway. What true course are you making good?

Accepted Answer

Option C: 291&deg;T. Converting compass to true course (Compass +/- Dev = Magnetic +/- Var = True) incorporates leeway. A southwest wind pushes the vessel to starboard/port depending on heading, altering the resulting true course made good to 291&deg;T.
