Day 40: Where's the Tug?

The rig in the top photo here was towing the tug Hammond Bay in the St. Mary's river when it disappeared. They looked back and the tug was gone. They later discovered that it has broken loose and sank in the channel. The USCG cutter Buckthorne was out to locate the sunken tug and mark it with a lighted buoy so river traffic can avoid the area where the tug went down. It was unmanned at the time of sinking.
