Question 591Navigation General

The correct answer is C) 315.0°. A vessel heading northwest is on a course of 315.0°. This is because northwest is one of the four cardinal directions, and the course heading for a northwest direction is 315.0°. The other options are incorrect because: A) 292.5° would be a west-northwest heading, not a northwest heading. B) 274.5° would be a west-southwest heading, not a northwest heading. D) 337.5° would be a north-northwest heading, not a northwest heading.
