Z flag
The Z flag is one of the international maritime signal flags.
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".
The Z flag when combined with four number flags (The leading two denoting hours, the trailing two denoting minutes) indicates Z Time (also called Zulu Time), a military and maritime term for Coordinated Universal Time (UTC)+0 (also known as Greenwich Mean Time (GMT)) expressed on a 24 hour clock. Thus this would mean 0800Z ("zero eight hundred zulu") equivalent to 08:00 UTC:
Or, more likely, the same information would be conveyed using repeat flags:
Under yacht racing rules, display of the Z flag indicates that a particular false start rule, the 20% Penalty Rule 30.2, is in effect: a boat on the course side (OCS) – that is, over the starting line – during the minute before the start will receive a 20% scoring penalty.
The Z flag has special meaning in Japan (as well as in naval history generally) due to its connection with and symbolizing of the Japanese victory at the Battle of Tsushima.
At the Battle of Tsushima on May 27, 1905, Admiral Tōgō raised a Z flag on his flagship Mikasa. By prearrangement, this flag flown alone meant, "The fate of the Empire rests on the outcome of this battle. Let each man do his utmost." (「皇國ノ興廢此ノ一戰ニ在リ、各員一層奮勵努力セヨ」). The Battle of Tsushima was one of the most important naval battles of history and this signal is, along with Nelson's signal "England expects that every man will do his duty" at the Battle of Trafalgar, one of the two most famous naval flag signals; the battle is of especial importance in Japanese national mythology.
The Z flag was raised on Vice-Admiral Nagumo's flagship Akagi before the aircraft were flown off for the 1941 Attack on Pearl Harbor (called Operation Z in its planning stages), explicitly referencing Tōgō's historic victory.
The carrier turned to port and headed into the northerly wind. The battle flag was now added to the 'Z' flag flying at the masthead... On the flight deck a green lamp was waved in a circle to signal 'Take off!'
