Sector 8. The Solomon Islands—Central and West Parts

8.7

Estrella Bay (Ghehe Bay) (7°55'S., 159°11'E.) is located on

the E side of a remarkable promontory. Kesuo Cove, the nar- row inlet off the bay, is about 0.4 mile wide at the entrance be- tween fringing reefs that also ring the shore.

8.7

Anchorage.—There is good anchorage anywhere in Kesuo

Cove. A vessel anchored off White Rock, which lies on the coastal reef close within the S entrance of the cove, in 29m, mud.

8.8 The coast between Ghasetataauro Rock (Gasetata-

turo) (7°55'S., 159°12'E.) NW to Cape Megapode has not been examined. It breaks for several bays and is fronted by many dangerous reefs and shoals. Vessels passing along this coast are recommended to keep at least 8 miles offshore.

8.8

Cape Megapode (7°48'S., 158°59'E.) is a low, rounded,

heavily-wooded point. With its fringing reef, it meets the sunken barrier. About 5 miles WSW of Cape Megapode is Mount Gatere, a conspicuous double peak, 540m high. From the cape NW, a submerged barrier reef extends to the Ghiz- unabeana Islands (Gijunabeana) (7°33'S., 158°42'E.), enclos- ing a lagoon, about 3 miles wide. The seas break at intervals over the reef when the swell is heavy. The reef apparently has no passage.

8.8

The Ghizunabeana Islands are a group of islands lying on a

reef. Rekata Bay, extending between these islands and the main island, contains several islets and dangers. It is reported that Rekata Bay is best approached from the NW, but the Penrose Patches, lying 2 miles ENE of Cape Pachena, and which component parts of a reef extending N and S, are difficult to distinguish.

8.8

Anchorage.—Anchorage has been taken, in 26m, mud,

about 0.6 mile NW of Taimihaza Island (Taimihaja). There was anchorage, in 37m, E of Memehana Island.

8.9 The coast WNW from Cape Paehena to Litundo

Point (Wreck Point) (7°31'S., 158°26'E.) is indented by several bays, densely wooded, and protected by a barrier reef, cut by several passages. The lagoon inside the barrier reef has not been surveyed.

8.9

Austria Sound (N Entrance) (7°28'S., 158°25'E.), leading

into Kia Bay, is 0.75 mile wide between the reefs extending from the Kakatina Islands and Rapita Island on the E and W sides. It is deep in the fairway through to Kia Bay.

8.9

Kia Bay (7°30'S., 158°25'E.), at the N end of the channel be-

tween Santa Isabel Island and Barola Island, is part of a lagoon contained between the barrier reef. Its outer part is deep and affords no anchorage.

8.9

Caution.—Durour Ridge, with depths of less than 457m,

lies almost 20 miles N of Cape Paehena. The ridge has been surveyed and was found to have three separate shoal patches, with depths from W to E of 7m, 11.9m, and 10m, respectively. It was reported (2002) that dangerous underwater rocks of un- certain depths lie 13 miles W of Durour Ridge in position 7°10.8'S, 158°22.2'E. Fish rafts, fitted with radar reflectors, are situated about 20 miles NE of the ridge. Apart from these dan- gers, the coast appears to be free of dangers in the approach.

8.10 Barola Island, which appears as a continuation of the

NW extremity of Santa Isabel, has a range of hills running its entire length. The N side is protected by a barrier reef which

215

lies 1 to 2 miles offshore, enclosing a partially examined la- goon.

8.10

The coast between Port Praslin and Cape Comfort (Lave

Point), the NW point of Bates Island, is low and wooded, and presents a broken appearance from seaward.

8.10

The barrier reef continues WNW from Cape Comfort to a

point about 10 miles NE of Kumboro Peak, at the NE end of Choiseul Island. That part of the reef extending 11 miles from Cape Comfort has not been surveyed, but the remainder, form- ing a barrier to the entrance to Manning Strait, has been sur- veyed.

8.10

Manning Strait is the passage separating the islands off the

NW end of Santa Isabel from those off the SE end of Choiseul Island and has not been completely surveyed. The strait is divided by the two island groups forming the Aravon Islands (7°27'S., 158°00'E.). Both groups, Kerehikapa Island to the W and Sikopo Island to the E, are featureless and uninhabited. Reefs extend from the E sides of each island affording shel- tered and good anchorage for vessels with knowledge of this area. In Sikopo Harbor, on the E side of Sikopo Island, anchor- age may be obtained, in a depth of 25m, in all seasons. Tides—Currents.—The pattern of tidal currents in Man-

8.10

ning Strait is rather complex, since the tides on the N coasts of Choiseul Island and Santa Isabel are mostly semi-diurnal, with a range up to 1.5m, while on the S coasts of those islands they are mainly diurnal, with a range of less than 1m; therefore, there is great difference even from the pattern at the N and S ends of the Arnavon Islands. Nevertheless, the tidal current in the main channel through the strait sets along it at a rate of less than 2 knots. Rates up to 3.5 knots have been observed over the shoal areas and in the restricted channels.

8.10

The current in Northern Passage sets through it at a rate up to

2.25 knots, while outside the passage it sets parallel to the barrier reef.

8.10

The current attains a rate of 2 to 4 knots in Kologilo Passage.

Slack water occurs in the passage at about half tide along the shore.

8.10

The current has a rate up to 2.5 knots in the three S passages.

Tide rips and eddies may be experienced S of the submarine barrier reef, and a heavy swell occurs at times in Pasco Passage and over the reef close W of it.

8.10

Depths—Limitations.—As defined by the 20m curve, the

barrier reef in the N entrance to Manning Strait is continuous from Suki Island to North Passage. West of North Passage, the reef becomes more broken, with deep water between the shoal areas. Within the 20m curve, the reef has isolated depths of 7 to 14m. Fahlander Shoal (7°11'S., 157°35'E.), about 6 miles NE of Cape Kumboro, has a least depth of 7m and breaks in heavy weather. The E edge of Fahlander Shoal has a depth of 8.2m, with lesser depths extending to the West. Depths of 5.5 to 9.1m lie about 2.3 miles S and 2.8 miles SE of the 8.2m depth. Wooding Patches (7°15'S., 157°43'E.) has depths of 15.6 to 22m. A 13.6m shoal, with an unexamined shoal patch close W of it, lies 1.5 miles WNW of Wooding Patches. Several shoals lie S of Wooding Patches; Asbey Reef, with a depth of 10.8m, lies 5 miles ESE of Wooding Patches, while Audrey Reef, with a charted depth of 6m, is located 6 miles further SE.

8.10

Laiena Rock, 5m high, is located about 0.8 mile NNW of

Silkopo Island, and is surrounded by an extensive reef. Haber- lin Reef (7°24'S., 158°02'E.), located about 5.5 miles E of Lai-
