The International Code of Signals (INTERCO) is an international system of signals and codes for use by vessels to communicate important messages regarding safety of navigation and related matters. Signals can be sent by flaghoist , signal lamp ("blinker"), flag semaphore , radiotelegraphy, and radiotelephony.
International maritime signal flags are various flags used to communicate with ships. The principal system of flags and associated codes is the International Code of Signals . [ 1 ] Various navies have flag systems with additional flags and codes, and other flags are used in special uses, or have historical significance.
As well as digit flags, the code used "repeat" flags so that only one set of digits was needed; thus the word do, coded as "220", used a "2" flag, a "first repeat" flag here serving as a second 2, and a "0" flag. [12] The end of the message would be indicated by an "end of code" flag (blue over yellow diagonally split). [10] [12]
In 1790 Admiral Lord Howe issued a new signal book for a numerary system using numeral flags to signal a number; the number, not the mast from which the flags flew, indicated the message. Other admirals tried various systems; it was not until 1799 that the Admiralty issued a standardized signal code system for the entire Royal Navy.
A designator flag is used to indicate if a flaghoist signal is meant to be interpreted as an ICS signal or as a naval signal. The U.S. Navy uses a set of 68 flags, including flags for each letter of the alphabet and each numeral to convey messages of tactical or administrative nature. [2] [better source needed]
In the system of international maritime signal flags, part of the International Code of Signals, the Z flag stands for the letter Z ("Zulu" in the NATO Alphabet) when used in letter-by-letter alphabetic communication. When used alone, it means "I require a tug" or, when used by fishing vessels near fishing grounds, "I am shooting nets".

As a code signal the International maritime signal flag Alpha (or "Alfa", signifying the letter "A") has the meaning of "I have a diver down; keep well clear at slow speed", [1] used to indicate that the vessel has limited maneuverability, and the presence of a diver in the water around the boat.
