That's actually really smart, shows a lot of composure: that guy single handedly saved hundreds of lives.The Concordia apparently hit some undersea rocks while coasting the Tuscan islands and started taking on water from a gash in the left side. The captain understood that his ship was in danger of sinking so he decided to bring it closer in toward the island of Giglio so it would settle down near the shore rather than sink in the open sea. The major inclination occurred as the ship settled in the low water near the island's port entrance.
Still kind of shocking to me that the sonar/sat wouldn't pick up the rocks and put up a huge alert saying there's a risk of collision.
