Vessels sailing under the Malaysia 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 Malaysia Country Flag is identified by it's fourteen, equally proportioned horizontal alternating stripes. The stripes are colored red and white, red at the top and finishing with white at the bottom. A light blue background fills the upper hoist, or left quadrant and is broken by a crescent moon that opens toward the fly, or right side. A yellow star lies directly in front of the crescent's opening, two of the fourteen wavy rays that protrude from it touching the upper and lower tips. The yellow colors are indicative of the Royal Color of the Malaysian rulers. The crescent is symbolic of Islam. The stripes are meant to symbolize the Federal government of Malaysia and the thirteen states that make up it's citizenship. The Federal stripe was an effort to avoid changing the flag after Singapore withdrew from the Union. The star represents unity between the states and the blue color represents unity of the people. The Malaysia Country Flag was officially adopted in 1950. The Flag is proportioned at a ratio of 1:2, height to length, respectively.
