Left button: activate or deactivate the joystick.
Right button: booster, to get more power if needed, e.g. if wind or current is strong.

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 more easily than in the traditional way – in any direction!
