COETIVY ISLAND CHART NO. 2557(INT7605) General Information 10.56 1 Topography Coetivy (7º 08'.00S, 56º 17'.00 E) is covered with trees, mainly coconut palms, except at the S end where it is more open. There are several sandhills but none higher than the trees and they cannot be seen from seaward. On the W coast of the island there is a small settlement. 2 The island lies on the E edge of a rectangular-shaped bank, occupying the N half of that side. It is partially surrounded by a coastal reef which partly dries and borders the entire E coast and which extends 23/4 miles farther SW, beyond the island, to occupy another quarter of the E side of the bank. There is an extensive area of rocks to the W and SW of the S half of the islands and reef. 3 Depths. A shoal area extends SSW of the island, bordering the reef mentioned above which partially dries at LW and on which the sea breaks heavily during the South-east trade wind. The main bank extends W from the islands a distance of about 9 miles, having depths between 6.7 m and 200m. Beyond the edges of the bank and E of the island the depth increases rapidly beyond 300m. 4 Overfalls from at LW about 1 mile W of the S point of the island. Tidal levels. Mean spring range about 1.0m; mean neap range about 0.3m. For further information see Admiralty Tide Tables Volume 3. Directions 10.57 1 Passage south of Coetivy. The island should be given a wide berth in order to avoid the bank and shoaled area described at 10.56. Passage west of Coetivy. From a position not less than 8 miles SW of the island a vessel on passage W of the island should proceed generally N, passing W of the shoaled area described at 10.56. Deep-draught vessels should attempt to pass not less than 10 miles W to avoid passing over the main bank. 2 Passage east or north of Coetivy. The plan is sufficient guide. Useful marks: Small sand cay (7°11'.31S 56°14'.78E). White cross, about 3m in height (7°08'.56S 56°16'.25E), situated in the settlement. Approaching from N the cross cannot be seen until it bears 120°. In 1978 it was reported as not having been sighted. Anchorages, landing and facilities 10.58 1 Anchorages. Excellent shelter from the South-east trade wind can be obtained anywhere on the bank W of Coetivy. The most convenient berth for communication with the shore is off the settlement, but it is advisable to anchor more than 5 cables from the shore due to the presence of coral heads. Previously, HM Survey vessels have found safe anchorage in the following positions: 2 In the position shown on the plan, in 26m, with settlement bearing 130° and the NW point of the island bearing 037°. In 15 m, 71/2 cables offshore, with the S point of the island bearing 1761/2° and the NW point bearing 036°. 3 Landing. A boat channel leads to a beach off the settlement. The channel should be used with extreme caution as there are coral heads up to 4 cables off the beach. Facility: hospital on Coetivy. Communications. Airstrip with links to Mahe.
