Your vessel is leaving New York harbor in dense fog. As the vessel slowly proceeds toward sea, you sight a green can buoy on the starboard bow. Which action should you take?

Correct Answer: Option A — Stand on, leaving the buoy to your starboard.

In IALA-B, green buoys are left to port when entering from seaward. If you are leaving the harbor, you are proceeding toward seaward; therefore, you must reverse the rule and leave the green buoy to your starboard side. This maintains the vessel within the designated channel boundaries.
