CHART-4177  Tillanchang Island

Tillanchong Island (8°28’.5N., 93°38’E.) lies with Cape Winifred its S end, about 34 miles E of Chowra Island.  Maharani Peak, the highest of several peaks forming a jagged ridge along the length of the island, lies in the center of the island and attains an elevation of 300m.
Tillanchong Island has been reported to be a good radar target up to 17 miles.
Paira Rock (8°35’N., 93°36’E.), 86m high, lies 0.5 mile NNW of Cape Maud, the N extremity of the island. Several detached rocks lie up to 1 mile off the W side of the island.
Isle of Man (8°24’N., 93°39’E.), a detached rock 111m high, lies about 2.8 miles SE of Cape Winifred. A chain of needle-like rocks lie between this rock and the cape.
Paria Rock has been reported to be a good radar target up to 19 miles.
An unexamined detached shoal, with a least depth of 27.5m, lies about 1.6 miles SW of Cape Winifred.  Castle Bay (8°27’N., 93°38’E.), which lies on the SE coast of the island about 2 miles N of Cape Winifred, is deep and clear in its central part.
A rock awash lies about 0.3 mile S of Castle Bay Point, the N entrance point of the bay. Foul ground, with depths of less than 9.1m, extends about 0.2 mile S from the rock. A dangerous wreck lies in shoal water about 0.3 mile SSW of Castle Bay Point.

During fair weather, anchorage can be taken in depths of 25.6 to 27.4m with Castle Bay Point bearing 062°, distant a little over 0.5 mile.
Terasa Dwip (8°18’N., 93°07’E.), roughly crescent-shaped and low in its central part, lies 6.5 miles SE of Chowra Island.  It appears as two separate islands from the offing. The N end of the island is 250 high. Hinam Village lies 4.5 miles SSE of the N summit and is only visible from seaward on a NE bearing. Laksi Village, which consists of some huts amongst the trees, lies 4 miles SE of Hinam Village. The village is hard to identify from seaward. Bengala Village lies on the E side of the island about 2 miles S of its NE extremity. Karawa Village lies 3.5 miles farther S.
Reefs extend over 1 mile from the N and S ends of the island, but less off the W coast.
Terasa Island has been reported to be a good radar target up to 25 miles.
Anchorage can be taken by small vessels with local knowledge close off Hinam Village in depths of 11 to 25.6m.  Small vessels can also anchor in a depth of 25.6m coral and coarse sand, SSW of Laksi Village, about 0.5 mile seaward of the coastal reef.
Small vessels with local knowledge sometimes anchor in a depth of 45.7m, about 0.5 mile off Bengala Village, with the NE end of the island bearing 006°, the E end bearing 146°, and the N end of Bompoka Island bearing 115°. This is a fair-weather anchorage.
Bompoka Island (8°14’N., 93°14’E.) lies 1.8 miles NE of the SE tip of Teressa Island and is 208m high. The intervening channel seaward of the fringing dangers is deep. Poahat Village lies on the W side of the island.
Small vessels with local knowledge can anchor about 0.3 mile offshore with the village in range 040° with the N peak of the island. Seaward of this position the depths decrease rapidly and caution is advised.
