This isn't the first time the Belle has been blown aground, rube. It's happened on a couple of other occasions that I know of, and come very close at still other times. The showboat has powerful maneuvering thrusters on it's sides that it uses in cases of high winds and also when docking. Apparently there was a failure of some sort with those thrusters after it got underway, otherwise they would never have taken it out in those windy conditions.
Those passengers will have interesting stories to tell when they get back home. They were well taken care of, being fed during the night and having a "lunch" for breakfast. And no accident related injuries occurred either, although a few received medical care for pre-existing conditions.
