Are the propellers counter-rotating?

Explanation:
The propellers are counter-rotating. On this vessel, two propellers turn in opposite directions to balance the rotational torque the engines would otherwise produce. This cancellation of torque keeps the stern from yawing to one side, giving you more predictable handling, especially at low speeds and when docking. It also helps each prop’s thrust work with the rudders for better maneuverability. If the propellers didn’t rotate opposite each other, you’d feel more steering effort and less stability, which is why counter-rotation is the chosen setup for this boat.
