Vessels sailing under the Dominica 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 flag of Dominica is a rather ornate flag that, since its inception in 1978, has gone through a few simple alterations, although it would take a trained eye to be able to spot the differences in the current flag than from previous versions. The flag was adopted by the nation on November 3, 1978. In 1981, the order of the colored stripes changed, and then in 1988, the location of the bird in the middle of the flag was flipped in order to face the other direction. The current version has slightly darker stars that circle the bird in the middle of the flag as well, although these slight adjustments did not alter the general design of the flag.
The background of the flag is a dark green and, in the middle of the flag, is a red circle. Standing proudly in the middle of the circle is a sisserou parrot, which is then surrounded by a series of 10 stars, which makes up the 10 parishes of the country. There are three stripes of colors running both horizontally and vertically. The yellow always comes first (on the top and on the left), followed by a black stripe and white stripe.
