Sector 7. The Solomon Islands—East Part

7.13

The coast of Malaita Island, a mountainous and thickly-

wooded island, is in places low and bordered by mangroves; in others it consists of dark coral, about 1m high, wooded to the edge of the water. The land rises gradually from the coast to the mountains in the middle of the island, which vary in height from 183 to 1,219m. About midway between the ends of the is- land is Mount Kolovrat, 1,303m high.

7.13

Maramasike, an island E of the SE end of Malaita Island, is

separated from it by a narrow channel running in a N and S direction.

7.13

Caution.—The relative positions of the NE and SW coasts

of Malaita Island, and also of the mountains within both coasts, are inaccurately charted. Care must be taken when approaching the coasts not to place undue reliance upon the charted positions of the mountains.

7.14 Mabo Harbor (9°36'S., 161°32'E.), entered about 6.8

miles N of Cape Zelee, is open to the E. This circular harbor has a reef extending 183m S from the N entrance point, and 137m N from the S entrance point.

Anchorage.—Good anchorage may be taken by small vessels, in 9.1 to 12.8m, in the middle of the harbor.

7.14 7.14

Port Adam (9°32'S., 161°33'E.) is formed between the E

coast of Maramasike and the Greenwich Islands, consisting of two low swampy islands, Fanelei Island (Halelei Island) and Malau Island (Mary Island), lying parallel to the coast. Both islands are covered with coconut palms and are easily disting- uished from seaward, although Fanelei Island is only about 1m high. At the S end of each island is a village.

7.14

There are depths of 7.3 to 35m in this port, but its shores are

irregular, and it is encumbered by projecting points, reefs, and islets. Walande Island lies near the coast about 1 mile WNW of Malau Island. Dead trees standing above water, mark the position of this sunken island.

7.14

There are three entrances to this port, and when a strong sea

breeze and an ebb tide coincide there are heavy overfalls, hav- ing the appearance of breakers from seaward. The S entrance, between the coast and the S point of Fanelei Island, is about 0.4 mile wide, but the navigable portion is reduced to about half that width by projecting reefs. A heavy sea occurs in this channel during the Southeast Trades.

7.14

Safe channel, the middle entrance, and the unnamed en-

trance N of Malau Island, are much wider, but the latter has some detached patches in it, which are, however, easily seen from aloft.

There is good anchorage within Malau Island, in 33 to 40m, and also within Fanelei Island, in 24 to 28m. Shoals extend up to 3 miles NW of Malau Island.

7.14 7.14 7.14

The coast NW of Port Adam to the N end of Maramasike is

little known. Auru Rock (Aulu Island), a small islet, lies close offshore, about 4.5 miles NW of Walande Island.

7.14

Maramasike Passage (North Entrance) (9°16'S., 161°16'E.)

is encumbered with several rocks and shoals. The passage is suitable only for light draft vessels; depths of less than 3.6m are in the narrows in the middle of the passage.

7.14

Anchorage.—Anchorage can be taken in Takataka Bay

(9°14'S., 161°15'E.), in 18.3 to 28m, S of the village on the NE shore of the bay. The head of the bay is shoal.

7.15 Manawai Harbor (9°04'S., 161°08'E.) is small but

protected, with mountain ranges extending to both entrance points. The entrance is only 0.3 mile wide but is deep. Anchor- age can be taken, in 18.3 to 37m, NW or SE of a 2.7m reef about 0.8 mile SE of the village at the head of the bay. Aio Island is a low and wooded island, about 3 miles N of

7.15

the entrance of Manawai Harbor; the N end of the island is about 0.5 mile offshore. The reef on which the island lies extends about 0.8 mile NW and 0.5 mile SE of the extremities of the island.

7.15

Aio Harbor is a lagoon formed on the W side of the island

between the fringing reefs. It affords anchorage in its center, in 29m, mud, but the entrance is very narrow as the reef on the N side extends about halfway across. A 3.8m shoal is close NW of the SE entrance point. The harbor should not be approached without local knowledge.

7.15

Anchorage.—Anchorage can be taken in Olomburi Bay

(Double Bay) (8°58'S., 161°04'E.), in 37m, about 0.3 mile off the S shore, in 51m, about 0.3 mile W of the N end of the reef at the entrance and, in 44m, inside Panchingi Point.

7.15

There is a small jetty for vessels drawing up to 3.6m in

Sinarango Harbor (8°53'S., 161°01'E.), about 8 miles NW of Olumbari Bay.

Anchorage, in 28 to 41m, is available with local knowledge in Sinalaka Bay.

7.15 7.15

Kingfish Shoal and an unnamed 9.1m shoal are close NE of

the entrance to Sinalaka Bay. The depth over Kingfish Shoal was estimated to be 5 to 7m in 1982, and was reported to ex- tend 2 miles further NW than charted.

7.15

Uru Island Anchorage affords anchorage 0.1 mile S of Uru

Island, in 12.8 to 32m. The chart should be used with caution, however, because a partial survey in 1971 showed extensive shoreline and depth changes.

7.16 Cape Arsacides (8°39'S., 161°00'E.) is low. but grad- ually rises to 610m about 8 miles to the NW.

7.16

Anchorage.—Anchorage with local knowledge may be ob-

tained during the Northwest Monsoon, in 18.3 to 22m, off Fak- anakafo, about 3.5 miles SW of Cape Arsacides.

The coast NW of Cape Arsacides to Urasi Cove is fringed by a reef extending as far seaward as 1 mile.

7.16

Manaoba Island, marked by a light, is a low wooded island surrounded by reefs lying close off the NE coast of Malaitao. The island is fringed by a coral reef and forms the N side of

7.16 7.16

Lau Lagoon. The narrow N entrance to the lagoon is deep and marked by beacons, and may be used by small vessels with local knowledge. The S entrance is only navigable by boats. There are two mission stations on the S side of the lagoon on the NE end of Malaita Island.

Tides—Currents.—Currents off the NE side of Malaita Island set SE and NW at an estimated rate of 3 knots.

7.16 7.16

Anchorage.—Anchorage may be obtained by vessels with

local knowledge off the NW end of Manaoba Island, in 74m, excellent holding ground.

7.17 Suaba Bay (Suafa Bay) (8°20'S., 160°40'E.) affords

anchorage, in 29m, about 0.6 mile from the middle of the head of the bay.

Ndai Island (7°54'S., 160°37'E.) is covered with trees from 46 to 52m high. A fringing reef surrounds the island and ex-
