Anchorages

Anchorage can be obtained on the SW side of Peremul Par, abreast the boat entrances to the lagoon, about 3 cables offshore in a depth of 18 m; local knowledge is necessary here, and also for another anchorage off the NE side of the reef, with the sand cay bearing 213 distant 4½ cables, in depths of from 18 to 22 m.

Off Kiltan anchorage is available but only in fair weather conditions. In adverse weather the swell conditions in the anchorage described below tend to be far more severe than those prevailing farther offshore.

The best position to anchor is reported to be with Kiltan Island North Light, bearing 129 distant 5½ cables, in depths of about 9 m, fine sand and coral; during S winds vessels should anchor a little closer inshore.

Vessels anchoring should keep well clear of a dangerous wreck, the position of which is approximate, which lies 2 cables N of the light.

Anchorage can also be obtained off the S end of the island, if the swell is not too heavy, about 3½ cables offshore in depths of 9 to 11 m, fine sand and coral.

Anchorage can be obtained, in fine weather, on the shoal areas extending SSW from the S end and NNW from the N end of Chetlat.

During the NE monsoon the best anchorage is off the S end of the island, about 4 cables offshore, with the SW end of the barrier reef bearing about 345 and the SW and SE points of Chetlat bearing about 010 and 039 respectively, in depths of from 11 to 18 m, as shown on the chart.

However, it has been reported that the SW end of the barrier reef does not provide a good mark; also, it was noted in January, that a vessel anchored close N of the charted anchorage lay across the anchor cable during both the in-going and out-going streams.

During the NE monsoon and in fair weather, anchorage can be obtained on the shoal which extends SSW from the S end of the island, in depths of from 7 to 15 m, sand and coral, as shown on the chart.

Good anchorage can be obtained on the bank between Agatti Island and Bingaran Island; the area is apparently free from charted dangers but vessels should proceed with caution. The recommended anchorage is with the NE extremity of Agatti bearing 215, distant 1½ miles, in a depth of about 13 m, coral.
