The channel is not closed: in fact what happened is that she was supposed to turn tightly into the channel and ... didn't. So she continued on ahead, burying herself an entire boat length into the sandbar. This is why she is stuck so tightly- a ~40 ft drought in ~20 feet of water, but she's so far stuck that she's cleared the channel. As for why, the investigation hasn't completed, there is no official ruling on who's fault it is, and a whole lot of lawyers telling people not to comment because this is big, big money.
