Tapaktuan, entered between Ujung Kupiah and Ujung Batu Itam, about 2 NM E, is entirely open S.
The shores of the roadstead are high and steep, and consist of wooded rocks and high hills.
It is reported to be fringed by a reef in most places, but abreast Tapaktuan, on the W side of the bay, there is a narrow channel through the reef, with a pier on its S side.
The NW portion of the bay is encumbered by Pakah Reef, which is marked by breakers and rollers.

Depths—Limitations

The pier can accommodate vessels up to 5,000 dwt, with a maximum length of 60m and a maximum draft of about 5m, although ships remain in the roads to load and discharge. Cargo is conveyed to and from shore by private barges.

Aspect

A very prominent house stands among those on the W shore of the bay.

Anchorage

Good anchorage may be obtained, in a great depth of 36m, mud, with the pier head bearing 324° and Ujung Kupiah bearing 270°. The anchorage is uncomfortable with winds between W and S.

Caution.—Batu Tungkat, a rock which dries, lies about 1 mile W of Ujung Kupiah. Batavia Rock, with a depth of 11.9m, lies about 0.3 mile NW of Batu Tungkat. Batu Kupiah, which dries, lies about 0.1 mile SW of Ujung Kupiah, the W entrance point of the bay.
