Sail Rock is the remaining uppermost part of a submerged volcanic edifice lying 7 nautical miles (13 km) southwest of Deception Island in the South Shetland Islands, Antarctica. It is 20 m long in southwest-northeast direction, 12 m wide and 30 m high. From a distance, the rock is reported to resemble a ship under sail, but at close range it is more like a house with a gable roof. The feature's name, which dates back to at least 1822, was probably given by sealers.
