Cruise ships are some of the most impressive vessels to ever take to the water. But how do they turn?
Cruise ships are so large, they can’t just spin around in a tight circle like smaller boats can. To answer this question, we need to look briefly at the design of these vessels and the way their propulsion systems work.
The Basics of Cruise Ship Design
Cruise ships are designed for maximum stability, which means that their center of gravity is as low as possible. This is important because if it was higher, it would put too much strain on the vessel and cause it to become unstable.
In order to keep the center of gravity as low as possible, these vessels have a very wide beam – or width – which helps them stay balanced in the water.
The Role of Propulsion Systems
Cruise ships have two primary methods of propulsion: propellers and thrusters. The propellers push the ship forward at high speed while the thrusters help with more precise movements such as turning. The thrusters are located on either side of the hull and they can be used independently or together.
How Does A Cruise Ship Turn?
When a cruise ship needs to turn, its captain will typically use both thrusters at different speeds; one faster than the other. This causes an unequal thrust force that creates a rotational force on the hull. This rotational force then turns the ship in whichever direction is desired.
Cruise ships have extremely powerful engines that allow them to turn at relatively high speeds compared to smaller boats. However, due to their size and weight, they still require more time and distance in order to complete a full turn.
Conclusion
Cruise ships turn by using both thrusters at different speeds; one faster than the other creating an unequal thrust force which causes a rotational force on the hull turning it in whichever direction is desired. Due to their size and weight, they require more time and distance in order to complete a full turn than smaller boats do.
