Sector 2. The Line Islands, the Cook Islands, the Samoa Islands, and the Tonga Islands

these three, and Tofonga (19°57'S., 174°28'W.) is the farthest NE.

2.59

A shoal, which consists of a narrow ridge with a least depth

of 1.8m, lies about 2 miles SW of Uanukuhihifu. This shoal is formed by a bank 2.5 miles long, extending in a WNW and opposite direction. A small reef, awash, lies about midway between this shoal and the barrier reef.

2.59

Ladd Reef, a small coral patch with depths of 0.6 to 0.9m,

lies 2 miles NNW of Uanukuhihifu; a similar patch exists 0.5 mile SE of Ladd Reef.

2.59

A bank of irregular soundings, all over 37m, lies NW of

Ladd Reef. The bank is marked by tide rips and overfalls dur- ing the strength of the tide, giving the appearance of shoal water.

2.59

There is an anchorage, in 33m, sand and coral, with the W

extremity of Uanukuhihifu bearing 212°, distant 1.1 miles, and the N extremity of Tofonga bearing 094°.

2.59

Tides—Currents.—The tidal currents set through with a

velocity of 4 to 5 knots flood to the E, and about 3 knots ebb to the W. During the E current with an E wind, there are heavy tide rips and overfalls dangerous to boats, but by keeping close to the reef on the S side they may be avoided. It is not advisable for vessels to use the passage except at the time of slack water.

2.60 Uiha Island (19°54'S., 174°24'W.), 3.5 miles NE of Tofonga, is 2.5 miles long N-S.

2.60

Island.

2.60

Tatafa Islet, 27m high, lies off the NW extremity of Uiha Ava Auhangamea, the channel separating Tatafa Islet on the

S from Uoleva on the N, is 0.4 mile wide between the reefs on either side. Two shoals, with depths of 5.5 to 8.2m, lie nearly in the middle of the channel.

2.60

Tides—Currents.—The tidal currents in Ava Auhangamea

run at the rate of 3 to 4 knots on the E current, which does not begin to make until 2 or 3 hours before HW. When there is an E wind, heavy tide rips and overfalls extend across the passage, making it dangerous for boats.

2.60

Uoleva (19°51'S., 174°24'W.) is covered with trees which

attain a height of 30m. It is the S island of a chain of islands, connected by reef, extending in a NNE direction for 14.5 miles. Off the NW coast of the island there are patches of reef, with foul ground between them and the shore, at a distance of 0.8 mile.

2.60

Hakau Faha, 2 miles NW of Uoleva, is a reef awash, which

always breaks. Nearly 1 mile WNW of Hakau Faha there are two patches having depths of 4.6 and 5.5m. Many coral heads have been reported to lie E of Hakau Faha.

2.61 Lifuka Island (19°48'S., 174°21'W.), 0.7 mile NE of

Uoleva, is the principal and farthest SW of the three largest is- lands of the group.

The seaward coast toward the N and S ends of the island is cliffy, but the remainder is low and covered with trees. On the W side of Lifuka Island, there are numerous reefs and

2.61 2.61

shoals within the 37m line. Beacons, which may have been destroyed, have been erected on some of the reefs.

Depths—Limitations.—The reefs in the vicinity of the an- chorages and in the approaches are so numerous that only those bordering the entrance channels are described.

A reef, which has a sandbar that dries 1.2m, lies just over 2

miles NW of the N end of Lifuka Island. Shoal water extends nearly 0.1 mile E of the reef, and shoal patches extend 0.5 mile W of the reef.

The shore reef extends 1.3 miles SW from the N extremity of Lifuka Island; the edge is usually indicated by breakers. Mariner Patch, a detached coral head with a depth of 4.6m,

2.61 2.61

lies 0.1 mile off the W part of the above reef and is marked by a buoy.

2.61

Lua Sii, marked by a buoy, is a coral patch with a depth of

2.1m WNW of Mariner Patch. It is not always seen in passing. There are two rocky patches W of Lua Sii which sometimes break.

Lua Matavai, with a depth of 2.7m, lies about 0.4 mile SSW of Mariner Patch and is marked by a buoy.

2.61 2.61

Hakau Mateialona, which dries, lies 0.6 mile WNW of Lua

Matavai. Sunken reefs extend 0.1 mile SE from it and a patch, with a depth of 5m, lies 0.3 mile NW of it.

2.61

Navigators should be aware that the buoys referred to above

may not be in place. Therefore, be prepared to navigate vis- ually, bearing in mind that the reefs in this area are difficult to make out at high water.

2.62 Hakau Tuaniu (19°47'S., 174°23'W.), which dries

0.3m, lies 0.5 mile SW of Hakau Mateialona. A coral head, with a depth of 4.1m, lies 0.1 mile S of the reef. Lua Tula, with a depth of less than 1.8m, lies 0.4 mile S of Hakau Tuaniu. Lee Patch, with a charted depth of 3.7m, lies 1 mile SW of Lua Tula.

Lua Vika, with a depth of less than 1.8m, lies about 0.6 mile ESE of Hakau Tuaniu.

Matavai.

Hakau Fusipala, which dries, lies about 0.3 mile SSW of Lua Buchanan Reef (19°47'S., 174°22'W.) is a small reef,

awash, about 0.4 mile S of Hakau Fusipala. To the N and E of it, foul ground and reefs too numerous to mention form part of the inner line of reefs fronting the anchorage off Pangai. This line of reefs is prolonged to the S by two large reefs, with a pass between them, for a distance of 1.3 miles.

2.62

Hakau Sela, a small drying reef, lies 0.5 mile SE of Buch-

anan Reef. In 1991, it was reported that a dangerous wreck, with a depth of 0.6m, lies 0.1 mile N of Hakau Sela. Rachel Patch, with a depth of 3.2m, lies 0.15 mile E of Hakau Sela. Hakau Vonu, about 0.5 mile S of Rachel Patch and about 0.3 mile offshore, is awash.

2.62

David Patch, with a charted depth of 3.2m, lies 0.15 mile N

of Hakau Sela; a patch, with a depth of 4.6m, lies 0.2 mile SW of David Patch.

Pilotage.—Local pilots are not available, but may be ob- tained at Nuku’alofa by prior arrangement.

Anchorage.—Anchorages are available off the W side of

Lifuka, and are described below, along with the channels lead- ing to them. The reefs and channels are marked by lights, bea- cons, and buoys, but such aids should not be relied upon. Addi- tionally, there is a lack of landmarks in the area to assist in fixing a vessel’s position. It may be necessary to navigate strictly by eye from aloft. On a calm day at HW the reefs are frequently impossible to see. Vessels are urged to exercise the appropriate caution.
