Which flag would suggest that a vessel is dragging anchor?

The Yankee Flag indicates that a vessel is dragging anchor because it is a specific signal used in maritime communication to alert other vessels and observers of this situation. When a vessel is dragging anchor, it may pose a risk of collision or grounding, so signaling this status is essential for safety. The use of the Yankee Flag in this context comes from the International Code of Signals, where each flag or combination of flags conveys different messages based on established maritime protocols. This allows for clear communication among vessels, especially in busy waterways or during poor visibility conditions.

The other flags listed do not convey the same message. Each of them represents different signals or messages, confirming that the correct response is related to the implications of the Yankee Flag specifically regarding the status of a vessel's anchoring.
