Ten Degree channel to Chowra Island - 407

Ten Degree Channel (09°45'N., 92°40'E.), which lies between Little Andaman Island and the Car Nicobar, about 77 miles to the S, is deep and clear of any charted dangers.   
Car Nicobar (9°10'N., 92°46'E.), the N island of the group, lies about 77 miles SSE of Little Andaman Island. The island is densely wooded, mostly coconut trees.
The island has been reported to be a good radar target up to 14 miles.
Sawi Bay (9°14'N., 92°45'E.) indents the NW coast, between Keating Point and Hog Point, about 3.5 miles to SW. Sawi Village lies 0.5 mile SE of Hog Point.  A light shows from a concrete tower on Hog Point.
The tidal currents off Sawi Bay set NE on the flood tide.
An observation spot lies on a small promontory that extends WNW from the coast about 1 mile S of Keating Point. Keating Point Light is shown from a round metal tower on the point; a racon and a radio beacon transmit from the light tower.
A light shows from a 13 m high concrete tower on Observation Point, 1 mile S of Keating Point.
A coral patch, with a least depth of 17.4m, was reported to lie about 0.7 mile NW of the observation spot. A 9.6m patch lies 0.8 mile WNW of the same spot.
Anchorage can be taken in a depth of 21.9m, rock and coral over a thin layer of sand, about 0.8 mile N of Sawi Village.  Anchorage can also be taken in similar depths just over 1 mile W of the observation spot. Small vessels with local knowledge can anchor closer inshore off the observation spot.
Arong Village (09°10'N., 92°43'E.) lies 3 miles S of Hog Point. Anchorage can be taken about 0.5 mile W of the village in depths of 16.5 to 20.1m. Vessels should approach the anchorage with the village bearing 090°.
Kimios Bay (9°07'N., 92°46'E.) is a slight indentation on the S side of the island. Kemois Village, fronted by a beach, lies close W of a well-defined entrance of a creek. A village lies close E of this entrance.
The tidal currents set ESE on the flood at a rate of 3 knots at springs and in the opposite direction on the ebb. Small vessels with local knowledge can anchor in depths of 18.3 to 21.9m, about midway between the two villages.
Kokana (9°07.5'N., 92°48'E.), a small village, lies about 2 miles SW of the SE end of Car Nicobar.
Mus (9°14'N., 92°47'E.), the principal village on the island and the residence of the Assistant Commissioner, lies 0.8 mile SE of Keating Point. The Village lies at the head of a small inlet and the village of Lapate lies 1 mile farther SE.
 Anchorage can be taken off Mus in depths of 13.7m, about 0.4 mile offshore, with the NE extremity of Car Nicobar bearing 284°. Vessels may drag anchor because of the strong currents at springs.
Vessels can anchor about 0.5 mile NE of Lapate Village in a depth of 21.9m.
Anchorage can be taken in a depth of 25.6m, about 0.5 mile offshore of either village.
Malacca Village (9°10'N., 92°49'E.) lies on the S side of a small bight about 6 miles SE of Keating Point. A small masonry jetty, which dries completely at LW, serves as a good landmark. Two groups of beehive-shaped huts lie close N and S of the jetty and lie out clearly in contrast to the jungle. A conspicuous two-storied house, painted white and green with a red roof, lies about 0.3 mile SSE of the jetty. A beacon lies close SE of the two-storied house. Two flagstaffs lie near the jetty, and two lie in the village.
A dangerous reef extends offshore close N of the jetty.  Stranded wrecks lie on this reef within 0.3 mile N and S of the jetty-head.
The Nicobar Islands extend about 160 miles SSE from Car Nicobar, the northernmost island of the group. These islands are a dependency of the Andaman Islands and are administered by the Assistant Commissioner who resides at Mus, Car Nicobar. The islands range from hilly and undulating to mountainous and volcanic. There are few rivers.
The Nicobar Islands are usually divided into three groups.
The N group consists of Car Nicobar and Batti Malv Island.  The S group consists of Great Nicobar and Little Nicobar together with their off-lying islets. The central group includes all the remaining islands of the Nicobar Islands. Nancowry Harbour, between the islands of Camotra, Nancowry, and Trinkat is perhaps the most important and best sheltered harbour.
The channels between the groups of islands and between the individual islands have irregular depths, but are for the most part deep and clear of dangers.
Batti Malv Island (8°50'N., 92°51'E.), which lies about 17 miles SSE of Car Nicobar, appears wedge-shaped from the offing. This very small island rises to a densely wooded peak about 73m high. The NW end of the island is low, but rocky cliffs lie on the other sides. Reefs appear to extend 0.5 mile off the NW, SW, and SE sides of the island. The 40m curve surrounding the island lies up to 5 miles SE and 2.8 miles N of the island. A light shows from a metal framework tower, 20m high, on the N side of Batti Malv.
Batti Malv Island has been reported to be a good radar target up to 11 miles.
