What does the term "overhead" refer to on a vessel?

The term "overhead" on a vessel specifically refers to the ceiling in a vessel or compartment. This area is located above the deck and serves several functions. It can include structural elements, insulation, and sometimes lighting fixtures. The concept of overhead is important for understanding the layout and design of a vessel's interior spaces, as it defines the vertical space that can be used for operations or living quarters.

Understanding the overhead is crucial for crew members as it helps in navigating confined spaces, ensuring that safety protocols are adhered to, and optimizing the use of available space within the vessel. The correct identification of this area supports effective communication and operations on board while also playing a role in safety and engineering considerations.
