It looks as if the dredging might take a bit longer than first thought. Work continued throughout the afternoon to try to refloat and salvage the dredge. It seemed to be stabilized by about 6 pm. A boat that was labeled "tow boat" was launched and being tied onto the barge when I had to leave to return to SA for a few days. Some of my family is still there and maybe they will send me some pictures of what happened next.
