As we already know, Captain Schettino was attempting a very close pass of the ships' port side, at less than one mile. Inexplicably, the ship was going too fast when it initiated the turn. What the navigation data seems to show is that the turn came too late and it wasn't strong enough, which may indicate a steering failure before the first hit. This idea seems reinforced by the fact that he didn't try to back down hard or twin screw—a maneuver that uses both propellers—one forward, one backward—instead of just the rudder to quickly turn the ship.
