Question 6Navigation Problems
70% to passYour vessel is steering course 299°psc, variation for the area is 7°W, and deviation is 4°W. The wind is from the southwest, producing a 3° leeway. What true course are you making good?
A
296°T
B
299°T
C
313°T
D
291°T
AI Explanation
The correct answer is D) 291°T. To calculate the true course, we need to apply the variation and deviation to the compass course, and then account for the leeway. The vessel is steering a compass course of 299°psc. Applying the variation of 7°W and the deviation of 4°W, the magnetic course is 299° - 7° - 4° = 288°M. With a leeway of 3° to the southwest, the true course being made good is 288° + 3° = 291°T. The other options are incorrect because they do not properly account for the variation, deviation, and leeway factors in the calculation.
