Question 1877Navigation General70% to pass
You are on course 303°T. To check the speed of your vessel you should observe a celestial body on which bearing?
AI Explanation
The correct answer is C) 123°.
To check the speed of your vessel, you should observe a celestial body on a bearing perpendicular to your course. Since you are on course 303°T, the perpendicular bearing would be 123°T. This allows you to accurately measure the change in the celestial body's azimuth over time, which can then be used to calculate your vessel's speed.
The other options are incorrect because they do not represent a bearing perpendicular to your course. Option A) 213°T is the opposite of your course, Option B) 090°T is too far off to the side, and Option D) 000°T is directly in front of your vessel, which would not provide the necessary perpendicular reference for speed checking.
