How Much of a Cruise Ship Is Below Water Level?

By Anna Duncan

Cruise ships are massive vessels that are often overlooked in terms of their complexity. Not only do they serve as floating resorts, but they also contain a variety of engineering and safety systems that ensure smooth sailing. One of the most interesting elements of cruise ships is how much of their mass is actually below water level.

The average cruise ship is made up of about 60-70% below the waterline. This is due to the fact that the majority of a ship’s weight comes from its steel hull, which needs to be below the surface in order to keep it balanced and afloat. This hull is made up of several layers of steel plates that are welded together and reinforced with ribs and bulkheads in order to provide strength and stability.

In addition to the hull, there are other components that make up a cruise ship’s underwater profile.

This includes propulsion systems such as engines and propellers, ballast tanks for stabilizing the vessel, as well as fuel tanks and various piping systems for supplying power throughout the vessel. All these items must be located below water level in order for them to function properly.

On top of all this, a large portion of a cruise ship’s total weight comes from its passengers and crew members, who are obviously located above water level! This means that even though much of a cruise ship is submerged, there is still a considerable amount above water level too.

Conclusion:

Cruise ships have an impressive underwater profile which makes up around 60-70% of their total mass. This consists primarily of heavy steel plates forming the hull, as well as other components such as propulsion systems, ballast tanks, fuel tanks, and piping systems for power distribution throughout the vessel. However, it’s also important to note that even though much of a cruise ship may be submerged beneath the surface, there is still plenty above water level too.
