Vessels sailing under the Jamaica 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 Jamaica Country Flag is represented by two crossed gold stripes from corner to corner. The areas above and below the stripes form isosceles triangles that are colored solid green, while the areas to the hoist, or left and fly, or right form isosceles triangles, both colored solid black. The Jamaica Country Flag is designated to hold a proportional ratio of 1:2, height to length, respectively. The Flag was officially adopted in 1962, being designed by a committee of representatives and marking the celebration of Jamaican independence upon the country's withdrawal from the Federation Of the West Indies. The green color is meant to symbolize the lush vegetation and fertility of this region. It is meant to inspire hope for the future. Black is representative of the hardships endured by the people of Jamaica throughout history, and the strength and determination they demonstrate in meeting those challenges. The gold is reminiscent of the plentiful sunshine the country enjoys. The Jamaica Country Flag is meant to inspire the citizens to achieve higher goals and continue to be innovative in creativity.
