Question 1872Navigation General

A) 312° is the correct answer. To check the speed of your vessel, you should observe a celestial body on the same bearing as your course, which in this case is 312°T. This allows you to use the celestial body as a fixed reference point to accurately measure your vessel's speed over ground. The other options are incorrect because: B) 090° would be perpendicular to your course, C) 000° would be opposite your course, and D) 222° would be the reciprocal bearing, none of which would provide an accurate speed measurement relative to your course.
