Which flag indicates that a tug is required?

The Zulu Flag indicates that a tug is required. The use of signal flags in maritime communication is crucial for conveying critical information quickly and efficiently. The Zulu Flag, specifically, is recognized internationally as a signal that demands the assistance of a tugboat, often due to the vessel needing help with maneuvering, docking, or in response to specific operational needs.

This flag is an essential part of safe maritime practices, as it ensures that nearby vessels and harbor services are aware of the need for assistance, promoting a safer navigational environment. Understanding the significance of the Zulu Flag can assist mariners in effectively communicating their requirements while at sea or in port, preventing potential accidents or operational delays. In contrast, the other flags mentioned—Yankee, One, and Two—do not carry the specific meaning indicating the necessity for a tug, which is why they would be incorrect choices in this context.
