Question 589Rules of the Road90% to pass
BOTH INTERNATIONAL & INLAND You see a red sidelight bearing NW (315°). Which direction may the vessel be heading?
AI Explanation
The correct answer is A) south (180°).
When you see a red sidelight bearing NW (315°), this indicates that the vessel is heading in a southerly direction. According to the Rules of the Road, a red sidelight is visible from the starboard side of a vessel, meaning the vessel is heading to the right of your position. Therefore, if the red sidelight is bearing NW (315°), the vessel must be heading in a southerly direction, which is 180° from your position.
The other options are incorrect because a vessel with a red sidelight bearing NW (315°) cannot be heading east (090°), west (270°), or northeast (045°), as that would not align with the location of the red sidelight.
