What does the Navy term "gear adrift" refer to in civilian terms?

The term "gear adrift" in Navy parlance refers to equipment or items that are not properly secured or stowed away as they should be. In civilian terms, this closely aligns with the concept of items being "not put away." This can imply that gear is lying around instead of being organized, which can lead to safety hazards or inefficiencies in operations.

Although the other choices touch upon aspects related to gear being unhandled, they don't encapsulate the complete essence of "gear adrift." For instance, while leaving something on the deck or implying that supplies are disorganized reflects a similar disorder, they don't specifically denote the implication of equipment not being stowed or secured properly, which is the core of "gear adrift."
