The master of the 1978-built tug Kristin Alexis sounded the general alarm as the vessel rocked and tilted after a Doun Shipping chemical tanker and another tug motored past on the Mississippi River, according to one account of a 2013 casualty.
As the wake continued to pour over the sides of the stricken towboat, water flooded into watertight doors that were allegedly left open, and flooded the engine room.
