What Is the Hull of a Cruise Ship Made Of?

By Anna Duncan

The hull of a cruise ship is the foundation of the vessel, and its construction must be strong enough to withstand the harsh elements of open sea. Cruise ships must also be able to glide through the ocean with ease, so the design must be efficient and streamlined. The materials used in constructing the hull are chosen based on these requirements, and many modern ships are built from steel.

Steel is one of the most popular materials for constructing cruise ship hulls. Steel provides a strong and durable framework for the ship, and it can be welded easily and quickly.

Steel is also relatively lightweight compared to other materials, making it easier to maneuver in heavy seas. Additionally, steel is resistant to corrosion and can last for decades when properly maintained.

Some older ships may have hulls constructed from wood or aluminum. Wood offers an attractive aesthetic, but it is not as durable as steel and requires more maintenance over time. Aluminum has similar advantages to steel but is more susceptible to corrosion when exposed to salt water.

The exterior of a cruise ship’s hull may also include protective coatings such as paint or epoxy resin. These coatings help protect against damage caused by barnacles or other sediment that may attach itself to the surface of the vessel during its voyage. The coating also helps reduce drag on the vessel, which helps improve fuel efficiency.


The hull of a cruise ship is one of its most important components and selecting the right material is essential for ensuring safety and performance at sea. Steel is typically used due to its strength, light weight, durability, corrosion resistance and ease of welding; however, some older ships may use aluminum or wood instead. Protective coatings such as paint or epoxy resin may also be applied over the exterior of the hull in order to provide additional protection from damage caused by barnacles or other sediment.
