You are underway on course 127°T. You sight a buoy with the topmarks shown in illustration D025NG below, bearing two points on the starboard bow. Which action must be taken?

Correct Answer: Option A — Ensure the bearings change to the right.

The illustration shows a North Cardinal mark. To pass safely, you must remain to the north of the buoy. With the buoy bearing two points on the starboard bow, you must ensure the bearing changes to the right to pass clear of the hazard on its northern side.
