Standing rigging refers to the system of cables and wires that support a sailing vessel's mast. These components are essential for maintaining the mast's position and stability while the boat is in motion. Standing rigging typically includes items like shrouds and stays, which are tensioned to keep the mast upright and secure. Unlike running rigging, which is used to control sails and adjust their position, standing rigging remains fixed in place. Proper maintenance of standing rigging is crucial for safety, as any failure can lead to mast collapse and potential hazards for the crew and vessel.
