Question

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

Accepted Answer

Option A: 153&deg;T. Applying chart work principles: compass 166° minus 3° West deviation gives magnetic 163°, minus 8° West variation yields true 155°. A west-southwest wind produces 2° leeway to port, subtracting 2° for a true course made good of 153°T.
