In a crossing situation, what does a single short whistle from one vessel signify?

• A. I intend to leave you on my port side.
• B. I intend to pass on your starboard side.
• C. I am giving way.
• D. I intend to stop.

Answer: (A)

In crossing situations, vessels use whistle signals to spell out their intended maneuver and which side they’ll pass on. A single short blast communicates: I intend to leave you on my port side. In practical terms, that means I will pass you on your port side (the left side as we go by). This specific signal helps both vessels coordinate so they don’t collide. It isn’t indicating giving way or stopping—that would be shown by different whistle patterns.
