Signal Flag Code

The Signal Flag Code is a system of using brightly colored flags to communicate messages between ships or with people on shore. Each flag or combination of flags represents specific letters, numbers, or messages, allowing marine vessels to send important information such as navigational instructions, safety alerts, or distress signals without words. This visual communication method is especially useful when voice communication isn’t possible. It provides a standardized and universally recognized way for ships of different languages and countries to exchange vital information while at sea.
