The straight baselines replace the low-water line of the coast with the exception of a narrow band in the north. This narrow band measures approximately 30 nautical miles in length and extends from the Bangladesh boundary at the Naaf River to the point a) on Oyster Island. A brief analysis of the straight baselines, taken from large-scale nautical charts, follows:

 

Points Length (Nautical Miles) Comments
a - b 36.0

Oyster Island is a small isolated island situated approximately 11.4 nautical miles from the mainland. Line a-b deviates from the general trend of the coast by c. 14".

b - c 30.1 Boronga point is situated a t the southern end of Myengun Kyun (isl.) . The entire coast from b-c is fringed with islands. Line b-c deviates from coast at an angle o f 12".
C - d 32.1 The line c-d deviates at an angle of 18' to enclose the large island of Cheduba within the internal waters of Burma.
d - e 42.5 This segment, 8" from the general trend of the coast, terminates at the southern end of the heavily-fringed coastline.
e - f 57.0 The straight baseline averages 18-20 miles offshore. Few islands exist in the neighborhood of the segment although many are situated close t o the shore. The line is approximately 12" from the general trend of the mainland.
f - g 33.0 Same general situation but approximately 12 nautical miles from the shore and at an anqle of 4'.
g - h 24.5 Same general situation except approaching coast; angle is 15" between segment and general trend.
h - i 13.5 Same but straight baseline now within 3 nautical miles of coast and angle is 2".
i - j 7.1 Shortest length of straight baseline on the Arakan coast. Straight baseline forms an angle of c . 10" to the general trend of the coast. The segment averages slightly less than 2 nautical miles from the coast.
j - k 29.0 The final point of the Arakan coast is situated on a reef ,which has a lighthouse thereon, near the Irrawaddy delta -- 13.8 nautical miles from nearest land. Angle measures c. 12" to the general coastal trend.
 
Gulf of Martaban
a - b 222.3

Point a is identical with the point k of the Arakan straight baseline. The closing line a-b is the longest straight baseline encountered in the world. The first segment remains with in 12" of the trend of the delta but the eastern two - thirds deviates at an angle of 60". At one point on the straight baseline, the nearest land is 75 nautical miles away and the mouth of the Sittang is over 120 nautical miles distant .

Tenasserim Coast
a - b 15.5 The straight baseline segment lies slightly over 12 nautical miles from the coast at an angle of 11" from its general direction . A large number of islands (+20) are situated close to the segment.
b - c 80.8 In the north b-c averages nearly 20 nautical miles from the mainland at an angle of 13" from its general direction. The number of islands is not great until south of the Savoy River (13" 31' North).
c.- d 17.9 A very large number of islands fringe the coast for the remainder of its extent southward. For the most part the straight baseline joins the outer most points. Three islets in this sector, however, are seaward of the straight baseline. The angle to the coast is c . 9".
d - e 29.0 The angle increases to 19" as t h e straight baseline extends to include outer islands .
e - f 19.2 The angle is  38' to the general trend o f the coast. Base point f is situated on a large island, over 75 miles from the mainland.
f - g 71.1 The number of islands in the vicinity of the straight baseline decreases markedly although many still fringe the coast. The angle of the straight baseline is 12" to the general coastal trend.
g - h 10.1 Same but the anqle is 9
h - i 38.1 The straight baseline draws nearer to the mainland ( c , 38 n.m.) and to the fringing islands ( c . 9 n.m.).The angle to the general trend of the coast is c. 15".
i - j 10.8 Same but the angle decreases to c. 10".
j - k 6.8 The shortest segment of the straight baseline terminates the limits with the southernmost Burmese island . Because the line is trending towards the shore the angle increases
greatly, to nearly 40"
Total 826.4 Nautical Miles

The twenty-one straight baseline segments total 826.4 nautical miles , forming all but approximately 30 miles of the Burmese baseline.The average segment length is nearly 40 n.m. The maximum leng h is 222.3 n.m. which forms a closing line for the Gulf of Martaban At no piont does the baseline extend seaward of the continental shelf of Burma. None of the base points are situated on the mainldnd of Burma. The ratio of water to land enclosed within the baselines is estimated to exceed 50:1.

Burma has not adhered to the Geneva Convention on the Territorial Sea and the Contiguous Zone.
