signal flags
Ship-to-ship communication
Signal flags are colored flags used to communicate between ships or across distances.
Each flag in a maritime signal system represents a letter, number, or specific message, allowing vessels to spell out words or convey standard meanings: The ship hoisted signal flags requesting a pilot.
Signal flags also appear at yacht clubs and in nautical decoration.
