Standing rigging refers to the fixed, non-moving wires, rods, or cables that support a sailboat's mast in an upright position. These structural, high-tension lines—including stays and shrouds—maintain mast stability and sail shape, usually made of stainless steel wire, rod, or synthetic fiber.

Key Components of Standing Rigging:
Shrouds: Wires on the port and starboard sides that provide lateral (side-to-side) support.

Forestay/Headstay: A stay supporting the mast from the bow, often used to hold the headsail.

Backstay: A stay supporting the mast from the stern.

Spreaders: Struts that extend from the mast to hold the shrouds at a wider angle, increasing support.

Turnbuckles/Rigging Screws: Adjustable fittings attached to the deck (chainplates) that tension the stays and shrouds.

Materials and Types:
1x19 Stainless Steel Wire: The most common, durable, and standard rigging type, consisting of 19 strands twisted together.

Rod Rigging: Solid metal rods used on racing yachts for improved aerodynamics and lower stretch, though harder to inspect for wear.

Synthetic Fiber: Modern, high-strength materials like Dyneema or Carbon fiber, popular for lower weight aloft.

Unlike running rigging (halyards/sheets), standing rigging remains fixed while sailing. It requires regular inspection for signs of wear, such as broken strands near swage fittings.
