Sector 1. Iles Tuamotu, Iles Marquises, Iles de la Societe, and Iles Tubuai

1.57 Makatea (15°50'S., 148°15'W.) is an island about 4

miles in extent in a NW-SE direction. The highest point of the island, 110m high, is near its N extremity. The island can be seen at 20 miles. Cliffs border the island and at the foot there is a narrow strip of low ground which is covered with coconut trees.

Tides—Currents.—Currents in the vicinity of Makatea set

W, when the Southeast Trades blow steadily, at a rate of 0.5 to 2 knots, except at Moumu Bay on the E coast, where it follows the shore in a NW direction. Off Port Temao an indraft is felt. During W winds, the direction of the current is often com- pletely reversed with a rate of 1 to 1.5 knots.

1.57

Aspect.—Port Temao on the W coast was the site of mining

and loading operations for phosphates. In 1971, the phosphate workings were abandoned and the port installations were no longer maintained.

Iles de la Societe

1.58 Iles de La Societe are divided into two groups for

administrative purposes and are known as Iles du Vent (Wind- ward Islands) and Iles Sous le Vent (Leeward Islands). Iles du Vent is composed of Meetia, Tahiti, Moorea, Tetiaroa, and Maiao. Iles Sous le Vent consists of Huahine, Raiatea, Tahaa, Bora-Bora, Atoll Tupai, Maupiti, Atoll Maupihaa, Atoll Manuae, and Atoll Motu One.

1.58

All of these islands, except Tetiaroa and those at the W end

of the group, consist of high volcanic mountains surrounded by coral barrier reefs.

1.58

Currents in the vicinity of Iles de la Societe have no constant

set. Except in their coastal waters, the current follows the direction of the wind. Easterly winds are the most frequent; consequently, W currents predominate; its rate depends upon the strength of the wind.

Regulations.—A continuous watch on VHF channel 6 is required in the territorial waters of these islands.

1.58 1.58

Meetia (Mehetia) (17°52'S., 148°04'W.) is the farthest E of

Iles de la Societe. The island is 435m high and has a diameter of 1 mile. The N side is remarkably steep, but on the S side the slope is more gradual.

1.58

There are two prominent rocks near the E extremity of the

island; a reef, which has no passage through it, extends about 1.5 miles E of the rocks.

1.58

In clear weather, Meetia may be seen for 60 miles.

Caution.—Breakers have been reported about 1 mile off the island’s SW point, but their existence is doubtful.

1.58

Tahiti

1.59 Tahiti (17°41'S., 149°22'W.) is the most important of

Iles de la Societe; it is 33 miles long NW-SE and is 15 miles wide. The island is formed by two ranges of high mountainous land, which are connected by the low narrow Isthme de Taravao (Isthmus Taravao), rising to a considerable height in each part from a low, and generally narrow margin of coast. Of these two parts the NW and larger is called Tahiti, and the SE, Presqu’ile de Taiarapu (Taiarapu Peninsula). Mont Orohena in the N part is 2,240m high, and Roniu, 1,323m high, is on Presqu’ile de Taiarapu.

1.59

The mountains are frequently enveloped in clouds, so

caution is necessary when making land at night. If coming from the N or E the light on Pointe Venus (Venus Point) should be sighted before closing the coast.

1.59

A barrier reef surrounds the island at a distance of 1 to 2

miles. Within this reef there are several good harbors, the principal ones are Papeete on the NW coast, and Port Phaeton on the SW side of Isthme de Taravao.

1.59

Winds—Weather.—The trade wind blows from the SE be-

tween May and September; between September and December it is more frequently from the E, and from January to April it is from between the NE and NW. The winds are modified by the high mountains of the island and by the action of land and sea breezes. Along the shore the prevailing wind is from the ENE to ESE.

1.59

If the wind is from the ESE it divides on striking Presqu’ile

de Taiarapu; the S portion blows along the S coast of Tahiti as far as Pointe Maraa, when it turns from the coast and blows toward the S point of Moorea. The N portion blows along the N coast as far as Pointe Venus, where it becomes a E wind. There it leaves the coast and blows toward the N point of Moorea.

1.59

Between Pointes Maraa and Venus there are generally calms

and local breezes which extend for a short distance into the channel between Tahiti and Moorea. The dividing line between the winds to seaward and the calm is very clearly marked. Should the wind be from the E or ENE it strikes the N coast

1.59

of Presqu’ile de Taiarapu, and the SW coast as far as Passe de Teputo becomes becalmed, while a breeze crossing the Isthme de Taravao blows from the E along the S coast of Tahiti as far as Pointe Maraa. There it turns away from the coast and leaves a calm between Pointe Maraa and Pointe Faaa.

In proportion, as the wind shifts to the E and ENE the line of demarcation between the breeze and calm, which begins at Pointe Venus, approaches the land again and blows along the coast to Pointe Fare Ute, where it turns toward the reef off Pointe Faaa, leaving the roadstead at Papeete calm.

1.59

At Papeete, land and sea breezes usually prevail, the former commencing about 2000 and lasting until 0700; the sea breeze generally sets in about 1100, blowing from NW, and subsides about 1700.

1.59 1.59

Tides—Currents.—Along the N coast of Tahiti the general

set of the current is to the NW, and on the S coast to the SE. With W winds the current is often reversed. In good weather the velocity of the current is about 1 knot, but with strong winds it sometimes attains a velocity of 3 knots. Off Presqu’ile de Taiarapu, with N winds, the set of the current is SE.

1.60 Pointe Venus (Venus Point) (17°29'S., 149°29'W.) is

the N extremity of the island. It is a long low point extending about 1 mile to the N from the foot of the mountains. The point is marked by a light.

1.60

A reef, awash, extends in an arc N, E, and W of the point,

about 0.5 mile from the beach, and there are probably shoal heads a short distance seaward of the line of breakers.

1.60

From Pointe Venus the coast trends 8 miles SW to Pointe

Tataa (Tatuu Point), which lies close S of Point Faaa, the NW extremity of the island. The fringing reef lies up to 0.9 mile off this coast and the 100m curve lies from 0.2 to 1 mile offshore.
