Vessels sailing under the Turkey 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 Turkey Country Flag can be recognized by it's red background. The red is broken by a white crescent moon, centered on a horizontal plane but offset toward the hoist side, or left of the flag with the crescent tips touching near or at the center. A white, five pointed star hangs centered between the tips, slightly offset from the crescent toward the fly, or right side of the flag. The star hangs just to the right of center on a vertical plane, but is centered horizontally. Centuries ago, the Ottoman Empire that ruled the region acquired the color red as an official representative hue. The color is meant to represent that historical affiliation. The Turkey Country Flag was officially adopted in 1936, but has been used unofficially as the national symbol of the country since 1844. The crescent moon and white star, or morning star are ancient symbols of the Islamic faith. They are meant to always face to the East. The Turkey Country Flag is designated to hold a proportionate ratio of 2:3, height to length, respectively.
