Looks like the Becker Rudder is used with a non-pivoting prop:

I was not referring to ALP tugs and have never mentioned them here. What you call "rotating propeller pods" are actually called Azipods. The Mackinaw utilizes them.I suspect the ALP was pulling, not pushing. In fact, all the video's I've seen of it, it's never pushing, always pulling, I do not believe it even has bumpers on the bow. It's prime duty is heavy anchor recovery and moving off shore oil rigs. Why the afterdeck is flat and just above the waterline and has rollers on the back to bring in anchors. They have a nice website you can visit that list the entire fleet, the power plants, winch capacities and bollard pull. One picture shows it pulling a supertanker at sea and it's cooking pretty good too.
They don't look like Lakes tugs at all. and they use rotating propeller pods that rotate 360 degrees so they never reverse the engines, just reverse the direction the prop faces. They can even motor sideways. If I remember correctly it has a compliment of 24 crewmen. The name of the pods escapes me right now.
