Question

Your vessel is steering course 197&deg;psc, variation for the area is 7&deg;E, and deviation is 4&deg;W. The wind is from the west, producing a 2&deg; leeway. Which true course are you making good?

Accepted Answer

Option C: 198&deg;T. Convert compass to true using the standard mnemonic 'Can Dead Men Vote Twice At Elections'. Compass course 197° plus 4° West deviation gives magnetic 193°, plus 7° East variation yields true 200°. Applying 2° leeway from a westerly wind pushes the vessel to starboard, resulting in a true course made good of 198°T.
