What does the term "Overhead" refer to?

The term "Overhead" specifically refers to the ceiling or the area above a person's head on a ship. In nautical terms, this is an important distinction as the overhead is integral to the ship's design and layout, providing not only a physical barrier above but also often housing essential systems such as electrical, plumbing, and ventilation lines that run throughout the vessel.

In a naval context, understanding the layout and terminology, including "overhead," is crucial for effective communication and safety aboard. Personnel need to be aware of overhead clearance when moving through spaces to avoid head injuries, especially in operational environments where quick movements are necessary. This terminology is standardized across the Navy, ensuring that all personnel, regardless of their role, can effectively understand and navigate the physical space of the ship.
