Whiskey Signal Flag (W) – International Nautical Signal Flag
The Whiskey signal flag, also known as the W nautical flag, is a distinctive blue flag with a white square center that represents the letter W in the International Code of Signals.
Traditionally flown by vessels to communicate a medical emergency, the Whiskey flag sends an important maritime message:
“I require medical assistance.”
Used by mariners around the world, the Whiskey flag is a powerful symbol of safety, cooperation, and the long tradition of communication at sea.
