In sailing, each flag represents a unique message. The worldwide system is the International Code of Signals, where flags have alphabetical equivalents and can represent specific messages. For example, the Alpha flag means "I have a diver down; keep well clear at slow speed," while the Bravo flag indicates "I am taking in, discharging, or carrying dangerous cargo." Learning the meanings of different flags is crucial for effective communication and safety at sea.
