70% to pass

You are on course 238°T. To check the course of your vessel you should observe a celestial body on which bearing?

A 180°
B 238°
C 328°
D 090°
AI Explanation

The correct answer is C) 328°. To check the course of a vessel, you should observe a celestial body on a bearing that is 90 degrees from your course. Since you are on a course of 238°T, the bearing to observe the celestial body should be 328°, which is 90 degrees to the right of your course. The other options are incorrect because: A) 180° is directly opposite your course, B) 238° is your current course, and D) 090° is 90 degrees to the left of your course, not the right.
