Vessels sailing under the United Arab Emirates Country Flag are required to have on board this flag as part of flag state requirements that derive from maritime regulations in the International Code of Signals and the International Safety Management (ISM) Code. These codes are published by the International Maritime Organization (IMO) as an ongoing effort to reinforce maritime safety procedures and communications to the international maritime community. Fleet management companies and ship owners are responsible to ensure that each vessel in their respective fleets have the appropriate flag signage onboard to be in compliance. This flag is used to identify the flag state a vessel is sailing under and to communicate with other vessels under the provisions of the International Code of Signals.
The United Arab Emirates Country Flag is represented by four stripes. Three horizontal stripes of equal proportions are colored green, white and black from top to bottom. A fourth stripe of red adorns the hoist, or left side of the flag, being of a similar width as the horizontal stripes. The Flag was officially adopted in 1971. Each color represents one or more specific events or traits relating to the seven Emirates that make up the Union. Black is meant to represent the violent medieval history of the region, and today has also taken on a meaning related to crude oil and it's production. The green stripe references the Fatimids Caliphate which occurred in the several hundred years surrounding the turn of the first Millennium. It has come to also represent fertility and vegetation in the region. Red is meant to represent the Ottomam Empire, while the white stripe may reference the ideals of peace and honesty. The United Arab Emirates Country Flag is designated to be proportioned in a ratio of 1:2, height to length, respectively.
