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.
