BOTH INTERNATIONAL & INLAND You are on a vessel heading due north and see the lights shown in illustration D051RR below one point on your port bow. This vessel could be heading in what direction?

Correct Answer: Option D — SE

Illustration D051RR shows a vessel displaying sidelights and a masthead light. If you are heading North and see these lights one point on your port bow, the other vessel is crossing from your port to starboard. To be on your port bow while heading SE, the vessel must be moving SE.
