Question

Your vessel is steering a course of 337&deg;psc. Variation for the area is 13&deg;W, and deviation is 4&deg;E. The wind is from the south, producing a 3&deg; leeway. Which true course are you making good?

Accepted Answer

Option C: 331&deg;T. Convert steering compass 337°psc using deviation 4°E to get magnetic 341°, then apply variation 13°W to find true course 328°T. A southerly wind pushes the vessel north, adding 3° leeway to starboard for a final true course made good of 331°T.
