The Southeast Atlantic comprises all the marine waters, bounded by a line beginning at a point on the west coast of the African continent at 6°04'36'' S latitude and 12°19'48'' E longitude; thence running in a northwesterly direction along a rhumb line to a point at the intersection of the meridian 12°00'E with the parallel 6°00'S; thence due west along this parallell to the meridian 20°00'W; thence due south along this meridian to the parallel 50°00'S, thence due east along this parallel to the meridian 30°00'E; thence due north along this meridian to the coast of the African continent; thence in a westerly and northerly direction along the coast of Africa to the original point of departure.
