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

Nice one mate
ReplyDeleteThank you
ReplyDeleteYou want to make good a true course of 038° T. The variation is 5° E, magnetic compass deviation is 4° W and gyro compass error is 4° W. A southwesterly wind produces a 4° leeway. What is the course to steer per standard compass to make the true course?

DeleteCan you show the solution to this? Thanks!
Deletehello if the Leeway is in the portside of the ship am i gonna add it or still subtract? thank you
