Your vessel is steering course 027° per standard magnetic compass (psc), variation for the area is 19°W, and deviation is 2°E. The wind is from the north-northwest, producing a 5° leeway. What true course are you making good?

Your vessel is steering course 027&deg; per standard magnetic compass (psc), variation for the area is 19&deg;W, and deviation is 2&deg;E. The wind is from the north-northwest, producing a 5&deg; leeway. What true course are you making good?

Accepted Answer

Option A: 015&deg;T. Applying compass errors (19°W variation, 2°E deviation) converts the 027°psc course to true. Accounting for a north-northwest wind producing 5° of leeway yields a true course made good of 015°T.
