Lower left button: activate or deactivate the joystick.
Lower right button: high mode, to get more power if needed, e.g. if wind or current is strong.
Upper left button: activate or deactivate “Dynamic Positioning System” (option).

Push the joystick to port or starboard and your boat goes sideways. Even “impossible” berths are now accessible.

Twist the top to rotate. Combine it with any other move to compensate for wind or current.

You can do all your slow-speed driving easier than the traditional way in any direction!
