A webcam aboard the Nordnorge, a Norwegian liner, captured an image of the sinking Explorer, which had taken on water through a fist-size hole punched into the ship's starboard. Water flooded the grinding engine room and eventually caused a power failure. Photo: Cruise Norway, via Associated Press
Built in Finland in 1969, the Explorer was designed to operate in Antarctic and Arctic waters. It was small, to move swiftly through dangerous waters, and had a double bottom, a second layer of steel. But the vessel did not have a double hull, a complete second steel sheath, the kind developed after the sinking of the Titanic. Photo: Michael S. Nolan/Lindblad Expeditions
Shortly before the boat sank The Chilean navy said the entire MS Explorer finally slipped beneath the waves Friday evening, about 20 hours after the predawn accident near Antarctica's South Shetland Islands.
