Each flag has a specific meaning, often representing letters of the alphabet, numbers, or specific messages like distress signals or navigational instructions. These flags are crucial for ensuring safe and effective communication between vessels, especially when radio silence is required or in situations where radio communication is not possible. The International Code of Signals, established in the mid-19th century, standardizes the meanings of these flags, allowing for consistent and clear exchanges of information among ships worldwide.
