Karang Passo (Indonesia)

Karang Passo, lying 2,5 miles NW of the light structure on karang Galang and 1,3 NM offshore, is a coral patch, with a least depth of 1,8 m and with depths of 7,3 to 9,1 m.

Batu Betata, a small islet, lies on the coastal reef about 2 miles W of Pasop Reef.

There is a passage on either side of Karang Galang.

On the W side between the reef and the coast of Pulau Batam, although not so wide as the E or main passage, has general depths of 11 to 14.6m.

Vessels with a draft of less than 7.9m can safely use this passage by day. Native pilots seldom use the E passage, where the depths are much greater.
