What does the term 'standing rigging' refer to?

The term 'standing rigging' refers specifically to the fixed, non-moving lines and components that provide support to the masts and other rigging on a sailing vessel. This includes wires or ropes that help to stabilize the masts in place and maintain the shape and position of the sails. The standing rigging is crucial for maintaining the structural integrity of the masts and ensuring that the rigging can function effectively under various conditions at sea.

In contrast, other options pertain to different aspects of a vessel's operations. Lines for moving equipment refer to the running rigging, which is used to control the sails and make adjustments to their position. Equipment for battle readiness does not directly relate to the terminology of rigging but rather implies gear and systems for combat scenarios. Cargo handling systems focus on the logistics of loading and unloading cargo rather than the support structures of the ship itself. Therefore, the definition provided aligns perfectly with the nature and function of standing rigging.
