Which signal is used to request assistance?

The Victor Flag is utilized to signal for assistance, particularly in maritime communication. When a vessel displays the Victor Flag, it indicates that it requires help, signaling its distress to nearby ships and maritime authorities. This flag is part of the International Code of Signals, which provides a universal way for vessels to communicate critical information, especially in emergencies.

The other flags mentioned represent different messages. The Whiskey Flag indicates that a vessel is in need of medical assistance, but it is not the general distress signal. The Hotel Flag signifies a vessel's presence in a port or anchorage, and the Xray Flag is used for when a ship is requesting a pilot, not for general assistance. Understanding the specific meanings of these flags is crucial for effective communication at sea, particularly during emergencies when timely assistance is crucial.
