Nautical signal flags are a colorful and practical way for boaters to communicate messages, identify vessels, and add authentic maritime character to a boat or yacht. The International Code of Signals assigns specific meanings to individual letter and number flags, allowing vessels to communicate visually when radio communication is unavailable or when a quick visual signal is useful.
