Semaphore Flags

Semaphore flags are a visual signaling system used primarily in maritime communication. Two flags are held in each hand to represent letters of the alphabet. By positioning the flags in different angles, a person can convey messages over distances, especially when voice communication isn't feasible. This method is efficient and can be used day or night. Semaphore is important for safety at sea, allowing ships to communicate crucial information like directions or warnings, especially in busy or restricted waters. It’s a practical skill still taught in some maritime training programs today.
