90% to passBOTH INTERNATIONAL & INLAND You are on a vessel heading due south and see the lights shown in illustration D051RR below, one point on the port bow. What direction could this vessel be heading?
A
NW
B
SE
C
SW
D
NE
AI Explanation
The correct answer is A) NW. The lights shown in illustration D051RR represent the navigation lights of a vessel heading in a northwesterly direction. According to the International and Inland Rules of the Road, when viewing these navigation lights from one point on the port bow (i.e., 1 point off the port bow), the vessel must be heading in a northwesterly direction. The other options are incorrect because a vessel with these navigation lights would not be heading in a southeasterly (B), southwesterly (C), or northeasterly (D) direction when viewed from one point on the port bow.
