Disney Wish Propulsion and LNG System Quiz

The video discusses the Disney Wish's new azipod propulsion system, highlighting its electric motor-driven propeller that enhances performance and maneuverability. The transition from conventional shaft line propellers to potted propulsion allows for greater design flexibility and efficiency. Additionally, the video introduces the LNG system, which uses liquid natural gas for cleaner emissions and better fuel efficiency. The ship's performance is tested, showcasing its speed, energy efficiency, and silent operation.

What is the main feature of the Disney Wish's new propulsion system?
