Captain and corporate responsibility

A have a question I have not seen raised on the cruise line disaster of the Costa Concordia when it ran aground January 13, 2012 off the coast of the Tuscan island of Giglio. Although the executives of the cruise line have said the captain was on an unauthorized route; it appears from local villagers that these ships have done this repeatedly in the past. With that said, I would think all of these large ships would have a GPS and tracking type devices, so operations at corporate would know where these ships are at all times. Wouldn't you think that after all this time, with these ships navigating an unauthorized route, that someone would have said, that is an unauthorized route, do not do that anymore. So before total blame is put on the captain, what about those who supervise the captains, and their actions on a daily basis. Hopefully this will come out in court and hearings. Trucking and delivery companies have tracking systems, and have done so for around 10 years. I would find it hard to believe these large ships, with so many people on them, would not have this technology.
