Between Tanjung Pertandangan and Tanjung Sinaboi, about 56 miles ESE, the only points of identification are the river mouths.
The mangrove covered coast is mostly muddy and low lying. The coastal bank, as far out as the 10m curve, is marked by fishing stakes and enclosures. Fishing boats range well offshore and at night display no lights. At times they work as far out as close S of the Kepulauan Aruah group of islands.
Caution.—A former mined danger area exists in the approaches to the Sungai Kualoh and the Sungai Panai in which it is reported to be dangerous to anchor, trawl, or engage in any sea bed activity. The area is best seen on the chart.

A dangerous wreck lies approximately 15 miles NNE of Tanjung Pertandangan.

Tanjung Pertandangan is low but shows up well from the N because of its high trees.
From Tanjung Pejudian, about 11 miles SSE of Tanjung Pertandangan, a spit with depths of less than 10m extends about 11 miles N almost parallel with the coast. The S end of the spit is fairly steep-to. Fishing stakes were reported to stand in the vicinity of this spit.
