deep 6-mile wide channel. Murilo Atoll, the E atoll, has a num- ber of small islets with coconut palms and other trees on a barrier reef. Nomwin Atoll has a number of low coral islets. Murilo Atoll has the greater part of its S reef submerged.

10.20

Most of the islands are found here. The N and NW sides of the atoll consist of a nearly unbroken reef, with openings at the NW end.

10.20

Extensive areas in the S and SE part of the lagoon have been

swept. Numerous coral patches, some of which almost dry, are found within the lagoon. The passes have been swept to depths indicated on the chart.

10.20

A wreck stranded on the NE portion of the reef is reported to

give a good radar return. Ruo Island, on the S side of the atoll, is reported to give a good radar return up to 16.5 miles. Strand- ed wrecks were reported to be on the W and S portions of the reef in.

10.20

Murilo Atoll should only be approached during favorable

conditions of light, due to the submerged reefs. The reefs fring- ing the entrances are usually visible by color or by breakers. Anchorage.—There are extensive anchorage areas within

10.20

the lagoon, but most of the area is unprotected from the pre- vailing winds.

10.20

Nomwin Atoll consists of some low coral islands, some of

which are densely wooded. Nomwin Island, on the S side of the atoll, has a rounded summit. Several islets and sandbanks of a shifting nature stand on the reef W of the island. There are two wooded islets on the W side of the atoll. A radio station stands on Fananu Island on the E side of the atoll. A jetty extends about 90m N from the N shore of Nomwin Island. The lagoon is encumbered with many coral patches, one of

10.20

which dries. A large area in the S part of the lagoon has been swept to a depth of 14.9m, with shoal patches swept to lesser depths, as indicated on the chart. The main and best entrance to the lagoon lies between the edge of the reef 2 miles NW of Nomwin Island and the reef 1.5 miles farther NW. The en- trance is divided into three passages by South Patch, awash, and North Patch.

10.20

Anchorage can be taken off the N side of Nomwin Island,

fairly sheltered from S and W winds, but open to the NE. An- chorage can also be taken WSW of Fananu Island. The strength of the NE sea and wind is broken by the barrier reefs.

10.21 Fayu (8°33'N., 151°20'E.) is a low densely-wooded

coral island. Reefs fringe the island to a distance of 0.5 mile offshore. The entrance to a small boat passage, with depths of 0.6 to 0.9m, lies on the NW side of the island. Several prom- inent rocks lie on the reef SW of the island. A stranded wreck of a 3,000 grt vessel lies on the N edge of the reef. The wreck was reported to give a reasonable radar return. Namonuito Atoll (8°40'N., 150°00'E.) is a large triangular-

shaped atoll. Pisaras, at the E end of the atoll, Ulul, at the W end of the atoll, and the Magur Islands, at the N end of the atoll, are the most important islands. The atoll reef is sub- merged for the greater part and is marked by the lighter color of the water over it. The reef appears to be in the process of formation and can be crossed at many places where it is sub- merged.

10.21

Pisaras Island has coconut palms and other trees growing on

it. Reefs extend NW and WNW from the island, enclosing a shallow and foul bay.

10.22 Ulul Island (8°35'N., 149°40'E.) is densely covered

with co-conut palms. A drying reef fringes the island. There is a radio station on the island.

10.22

The reef forming the rim of the atoll has charted depths of

0.9m to over 18.3m and can usually be identified by the discol- oration of the water and by the action of the sea. The lagoon is not of uniform depth. Except for a 5.5m patch, located 14 miles W of Pisaras island, and a detached reef, with depths of 2.7 to 3.7m, located about 6 miles NW of Pisaras, there appears to be no less than 9.1m on the scattered coral heads.

10.22

Vessels can cross the atoll at any of the swept areas. An ex-

cellent place to cross is at a position about 8 miles W of Pisaras Island. Another good position at which to cross the reef is at a position 6 miles SE of Magur Island.

10.22

Anchorage.—There is reported to be good anchorage in the

swept area NW of Pisaras. Protection is afforded from E and SE winds.

During W winds, vessels can anchor 0.5 mile off the E side of Ulul Island, in 27m.

10.22 10.22

Vessels can anchor outside the lagoon, in 55m, about 0.3

mile off the S part of the W side of Ulul. There is limited space, but some protection is afforded against the prevailing NE winds.

10.22

Caution.—The island has been reported (1993) to lie 1.5

miles SE of its charted position. 10.23 Pulap Atoll (7°36'N., 149°25'E.) consists of three low

islands lying on the same reef. Pulap Island, the N of the three islands, is fertile and has many coconut trees on it.

10.23

Detached reefs, with depths of 9.1 to 13.7m, lie along the

atoll reef and inside the lagoon. They are hard to distinguish. The submerged reefs on the E and SW sides can be discerned under favorable conditions of light.

10.23

Anchorage.—The lagoon is exposed to strong winds and

heavy swells. The best anchorage is about 1 mile S of Pulap Island, in 27m, sand. Vessels can take fair weather anchorage off the N side of Tamatam, the S island of the atoll.

Caution.—Hitchfield Bank, with a least depth of 9.1m on its E edge, is located about 12 miles ENE of Pulap Atoll. Shoals, with depths of 9.1 to 22m, have been reported to lie

10.23 10.23

up to 16 miles W of the bank. 10.24 Puluwat Atoll (7°21'N., 149°11'E.) consists of five

coral islands lying on the same reef. Puluwat and Alet, the two largest islands of the group, have breadfruit trees at the middle and coconut palms along the shores. The smaller islets are wooded, but have few coconut palms. A white concrete tower, 40m high, stands on the NW end of Alet. There is a radio station on Puluwat.

10.24

A coral patch, with a depth of 18.3m, is located about 1.3

miles NW of the NW end of Alet. Shoaling was reported between this patch and the NW end of the island.

10.24

Enderby Bank, with a depth of 16m, coral, lies about 3 miles

WNW of Alet. A detached 12.8m patch lies about 1.5 miles SE of Puluwat. Uranie Bank, which extends about 17 miles SE from Puluwat, has depths of 11 to 61m. On its NE part, about 9.5 miles E of Puluwat, there is a depth of 11m which is marked by discoloration.

Anchorage.—Anchorage can be taken outside the lagoon, in 13.7m to 18.3m, about 1.8 miles SSE of Alet. The anchorage
