This is a screen capture at Cal Maritime of a Transas simulation of a Conventional Twin Screw tug towing a tanker Ship's speed is about 7 knots. The view is mostly from the advantage point of the starboard bridge wing. The towline is approximately 300 feet long and the tug is not utilizing a gob rope or pins for this exercise. As the tug moves to starboard it gets beyond the point of no return and is capsized by the towline which parts. The tug is pulled alongside stern first even though the rudders are hard left the engines are on full ahead. The tug does not right itself because of down flooding. The side doors on the tug are presumably open.
