I must admit, after watching both the NATGEO and the DISC shows, the DISC show was the better of the two in that it finally explained the change of course, after hitting the rocks, that Concordia took that saved so many lives.
I first thought the Capt had turned the ship and tried to beach her, but without any power, that wasn't possible. The DISC show, with their track and expert commentary showed that the winds essentially blew the ship into the rocks and saved many lives. Had she been in deeper water she would have capsized and taken a lot of people with her.
