While proceeding along the Norwegian coast on course 039°T, you sight the black- yellow-black banded buoy shown in illustration D021NG below, bearing 053°T. What action should you take?

Correct Answer: Option D — Alter course to 060° and ensure that the true bearings decreases

A black-yellow-black banded buoy is a West cardinal mark, indicating safe water to the west. With the buoy bearing 053°T, you are currently east of the mark. Altering course to 060° and ensuring the bearing decreases moves your vessel further west, safely clearing the danger marked by the cardinal buoy.
