Just saw that the ship has been refloated. Maybe this was all part of a white or black hat operation. But if it is, we’ll all be the last to know what it was all about. Perhaps the blockage wasn’t about the ship Evergreen itself. Maybe some operation took place on one of the other ships that was rerouted or was waiting in the queue.

ThanQ for that link. This article is the best I have seen in explaining how and why the ship was stuck in the Canal.
