The term used to refer to the walls of a ship is "bulkheads." Bulkheads serve as vertical partitions that divide the ship's interior spaces to provide structural support and facilitate watertight integrity. They are essential for maintaining the ship's stability and safety, particularly in the event of flooding or compartmentalization issues.

In contrast, decks refer to the horizontal surfaces of a ship where personnel can walk or operate equipment, while the hull is the watertight body of the ship that provides buoyancy and external structure. The superstructure is the part of the ship that is above the main deck and includes components like bridges and other raised structures. Understanding these distinctions helps clarify the role of bulkheads in ship design and function.
