Your vessel is steering course of 197° psc, variation of the area is 7° East and the deviation is 4° West. The wind is from the west producing a two-degree leeway. What true course are you making good.
Given:
Compass Course = 197°
Variation = 7° East
Deviation = 4° West
Leeway = 2°
What is asked?
Course made good
Solution:
In correcting a compass, that is compass to true:
+ if east
- if west
Compass Course = 197°
Deviation = - 4° W
Magnetic Course = 193°
Variation = + 7° E
True course = 200°
Leeway = - 2° (wind is from starboard, so subtract)
198° T is the course made good
