Gopnath Point, the W entrance point of the Gulf of Cambay, is moderately high, with a conspicuous light structure and bungalow on it. A temple, 23m high, lies near the coast, about 0.8 mile N of the point.

A reef, which dries 2.7m, extends about 1.5 miles ENE from Gopnath Point.

Gopnath Shoals, nearly steep-to on the E side, extend about 3.5 miles NNE from about 2 miles ENE of Gopnath Point. The shoals consist of a reef, which dries from 1.2 to 2.7m, and several patches with depths of less than 5.5m.

Sultanpur Shoals extend about 4 miles NNE from the N end of Gopnath Shoals to about 9 miles NNE of Gopnath Point, then W to the coast. These shoals consist of drying rock, sand and clay, and numerous patches with depths of 0.6 to 5.5m.
