Well, at the "Bugsier 2" is no reverse gear! You have to turn the whole thruster to get backwards thrust. That's how it works in real. Unfortunately the developers couldn't (or wouldn't..
) implement the correct levers to the tug, they are of course without any red or green parts and you can push the stick just into one direction. At the "Ocean Star" we could have a reversing system, because she is electric driven. So can choose, if you want to turn the azipod or reversing the prop's spin.
Best regards
