The Nautical Flag System is a method of communication used at sea, employing flags to convey messages between ships. Each flag represents a letter of the alphabet or a specific meaning, allowing sailors to send important information quickly and effectively. This system is essential for safety and coordination in maritime operations. Flags can be combined to form messages, and specific flags indicate common maritime signals, such as distress or the need for assistance. The International Code of Signals is a standardized set of flags used globally, ensuring that sailors from different countries can understand each other while navigating the oceans.
