What are Nautical Flags?
Nautical flags are specially designed flags in distinct colors which can be used to signal from ship to ship, or ship to shore. In addition to an internationally recognized signaling code, many nations have specific nautical flags of their own, but ships are able to communicate through the international code with ships from other nations. These communications are used to exchange information such as news, information about hazards, or requests for assistance. Nautical flags are also known as signaling flags, because of their use in signaling information.
