Ujung Raya (Ujung Raja is a lofty promontory rising precipitously from the sea and easily recognized from all directions; there are depths of 21.9m at a short distance from it.
A number of sunken dangers lie near the coast rendering it advisable to give it a berth of 5 or 6 miles, especially at night.
Most of the dangers are steep-to, as is the coast in most places, but they are generally seen by the surf breaking over them.
There are numerous prominent headlands and mountains by means of which the position of a vessel is easily verified.

An indifferent bottom almost everywhere, and the heavy ocean swell and poor shelter from W winds, render most places on this portion of the W coast as undesirable anchorages. 

The coast between Ujung Raya to Teluk Rigaih, about 57 miles SSE, is very irregular and has many prominent headlands, with bays between, none of which afford secure anchorage during the Southwest Monsoon.
