Sailboat lines and rigging fall into two families: standing rigging (the fixed wires that hold the mast up) and running rigging (the movable ropes that raise, trim, and shape the sails). Learning the correct names—shrouds, stays, halyards, sheets, outhauls—lets you understand any set of sailing instructions and control your boat with confidence.

| Control lines | Fine-tunes sail trim | Movable | Traveler, cunningham, vang |
What is standing rigging on a sailboat?
Standing rigging is the fixed set of wires (or rod/composite on some boats) that holds the mast upright and stationary under load. It does not move while you sail, but it carries enormous tension and is critical to safety. The main elements are:
- Shrouds: wires that stabilize the mast side-to-side (laterally).
- Stays: wires that hold the mast fore-and-aft—the forestay at the bow and the backstay at the stern.
- Spreaders: horizontal struts on the mast that spread the shroud loads and improve the support angle.
Because the forestay carries the headsail, many modern boats add a furling unit to it so the jib or genoa can be rolled away from the cockpit.
What is running rigging and what are the main lines?
Running rigging is the movable rope that controls the sails. These are the lines you handle every time you sail:
- Halyards: raise and lower the sails (main halyard, jib halyard, spinnaker halyard).
- Sheets: trim the sails in and out to set their angle to the wind—for example the jib sheet adjusts the jib.
- Outhaul: tensions the foot of the mainsail along the boom to flatten or deepen it.
- Downhaul / cunningham: tensions the luff of the sail against the mast.
- Traveler: a sliding car that positions the mainsheet athwartships to control mainsail angle.
Running rigging is chosen for low stretch and grip. Keeping halyards and their shackles in good order—and stowing tails neatly—keeps the cockpit safe and the sails setting cleanly.
How do I choose the right lines and rigging?
The right setup depends on your boat's size and how you sail. Racing crews favor lightweight, low-stretch lines (often with high-modulus cores) so the sails hold their shape precisely. Cruising sailors prioritize durability, easy handling, and good grip in the hand. Match line diameter to your clutches and winches, and size furlers and hardware to your boat's length and rig loads.
How do I maintain sailboat rigging?
Regular inspection keeps your rig safe and extends the life of every line:
- Inspect standing rigging for corrosion, cracks, or broken strands at the terminals.
- Check running rigging for chafe, glazing, and wear—replace lines before they fail.
- Lubricate and service moving parts such as blocks, cars, and winches.
- Rinse with fresh water and store lines out of UV to prevent sun and salt damage.
Frequently asked questions
What is the difference between standing and running rigging?
Standing rigging is the fixed wire that holds the mast up and does not move while sailing; running rigging is the movable rope—halyards and sheets—that raises and trims the sails.
What is a halyard?
A halyard is a line used to raise (hoist) and lower a sail. Boats typically have a separate halyard for the mainsail, headsail, and spinnaker.
What is the difference between a sheet and a halyard?
A halyard hoists a sail up, while a sheet trims that same sail in and out to set its angle to the wind. For example, the jib halyard raises the jib and the jib sheet trims it.
What are shrouds and stays?
Shrouds are the wires that support the mast side-to-side, and stays support it fore-and-aft—the forestay at the bow and the backstay at the stern.
What is an outhaul used for?
The outhaul tensions the foot of the mainsail along the boom, flattening the sail in stronger wind and deepening it in lighter air.
