In naval terminology, what term is generally used to describe both fiber and wire?

The correct term used in naval terminology to describe both fiber and wire is "line." In the context of sailing and naval operations, "line" is the general term that refers to any cordage, whether it is made from natural fibers or synthetic materials, including wire. While "rope" is commonly used in everyday language to refer to a thicker type of line, in naval terminology, it specifically refers to a type of line that is traditionally made from fiber materials.

Rope doesn’t encompass wire, which is important in many naval applications. Additionally, "cable" generally refers to a stronger form of line, typically made of wire, while a "hawser" is specifically a type of thick rope or line used for mooring or towing vessels. Therefore, "line" serves as the inclusive term that accurately describes both fiber and wire in the naval context.
