What is the term used to describe the wall of a ship?

The term "bulkhead" specifically refers to the vertical partitions or walls within a ship's structure that divide the interior space into compartments. These walls serve several purposes, such as providing structural integrity, enhancing safety by creating watertight compartments, and facilitating the organization of space within the vessel for different functions or areas.

In a nautical context, each of the other terms has different meanings: the "deck" refers to the horizontal surface that forms the roof of a ship's hull, providing space for operations and accommodations. The "hull," on the other hand, denotes the entire outer structure of the ship that provides buoyancy and protects the interior from water. The "transom" is the flat surface forming the rear end of the hull. Thus, while they are all related to ship structure, "bulkhead" is the precise term for the walls that partition compartments within the vessel.
