Boat Flags - Nautical Flag Code Signals

Nautical flags have been in existence for more than 150 years. They remain an important way for sailors to communicate between land and sea. The International Code of Signals was published by the British Board of Trade in 1857. It was updated in 1932 and 1969. The flag system is still used at sea today though their use serves as more of decorative purpose during special occasions and ceremonies. However, when modern technology fails, the age-old flag system remains the only means of communication at sea.
