A point of interest here is the change of color of the graphic for the ship's position. It changes from green to yellow. In the AIS color scheme; Red indicates an identified ship that is considered a potential danger; green indicates an identified ship that is not a potential danger; yellow indicates an "unidentified" ship that is not a potential danger.
So why did the Costa Concordia become an unidentified ship? Perhaps it went from green to yellow because it lost power to the equipment that transmitted some of its data. Or perhaps Qastar interpolated the data for the ship when its speed dropped below a certain value. If this happened, the AIS plotter could no longer determine exactly how it was moving through the water.
Meanwhile, given what we're seeing here, it was quite a piloting feat to lay the ship on that sandbar.

From most recent data, the skipper was having dinner with a hot 25 year old babe and was more worried having his dessert (use your own imagination as to what it was) than piloting the ship. There is a recommended GPS track for that area and he obviously disregarded it. Let's see how this one plays out in the media court......
Go for it.
I'm going to go out on a limb here and say the captain of the Costa Concordia is All Done, regardless of his efforts to put the ship on the bar.
