What does the Yankee Flag signify in maritime communication?

The Yankee Flag in maritime communication signifies "Dragging anchor" or "Visual Comms duty." This flag is part of the International Code of Signals, which utilizes flags to convey specific messages between vessels. When the Yankee Flag is raised, it alerts other vessels that the ship is having difficulty maintaining its anchor position, which is crucial information for safety on the water. This signal helps prevent collisions or accidents that could arise from a drifting vessel, enabling nearby ships to take appropriate precautions.

In the context of maritime safety, the ability to communicate crucial information visually allows for effective maneuvering and management of navigation among vessels. The other options do not pertain to the meaning of the Yankee Flag, as they refer to different signals and situations not covered by this specific flag's designation in the code.
