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