Running rigging is the collection of ropes and lines used to hoist, lower and control a yacht's sails. Halyards raise sails, sheets control their angle to the wind, while reefing lines, outhauls, vangs and other control lines adjust sail shape and sail area.
This guide gives an overview of the main running-rigging systems, rope choices and signs that replacement may be required. For model-specific indicative lengths and diameters, use our Yacht Rigging Database.
What Is Running Rigging?
Running rigging moves as the sails are hoisted, lowered or adjusted. This distinguishes it from standing rigging, which supports the mast and includes the shrouds, forestay and backstay.
- Standing rigging: supports and stabilises the mast.
- Running rigging: raises, lowers and controls the sails.
Main Parts of a Yacht's Running Rigging
Halyards
Halyards are used to raise and lower sails. Typical examples include the main halyard, genoa or jib halyard and spinnaker halyard.
Sheets
Sheets control the angle and trim of the sails. Common examples include the mainsheet, genoa or jib sheets and spinnaker sheets.
Reefing & Control Lines
Reefing lines reduce sail area, while outhauls, cunninghams, downhauls and vang or kicker systems are used to adjust sail shape and control.
Polyester Double Braid
A practical choice for many cruising halyards and sheets where handling, durability and value are important.
Dyneema Performance Halyards
Low-stretch, high-strength rope for applications where precise sail control and reduced weight are important.
Choosing the Right Running Rigging Rope
The best rope is not determined by yacht length alone. The sail area, expected load, rope construction and the equipment through which the line runs all matter.
Polyester
Polyester double-braid ropes are widely used for cruising running rigging because they offer good handling, durability and abrasion resistance at a sensible cost.
Dyneema & Low-Stretch Rope
Dyneema-core ropes provide high strength and low stretch and are commonly selected for performance halyards and other applications where movement under load needs to be minimised. They can also be used on cruising yachts where those characteristics are beneficial.
Do not select diameter from breaking strength alone. The rope also needs to work correctly with the yacht's sheaves, rope clutches, organisers, blocks and winches.
For more detail, see our Running Rigging Rope Selection Guide and Running Rigging Rope Size Guide.
When Should Running Rigging Be Replaced?
There is no single replacement interval that applies to every yacht. Rope life depends on construction, loading, UV exposure, chafe, contamination, storage and how frequently the boat is used.
Inspect running rigging regularly, paying particular attention to:
- localised chafe or broken cover fibres;
- flattening, glazing or hard areas;
- exposed or damaged core material;
- wear where ropes pass through clutches, sheaves or blocks;
- damaged stitching, whipping or spliced terminations;
- unexpected slipping or changes in handling under load.
Slipping does not automatically mean the rope itself is worn out. Rope diameter, clutch condition, contamination and hardware compatibility should also be checked.
Maintaining Running Rigging
Keep lines clean, inspect high-wear areas and check that sheaves, blocks, organisers and clutches rotate or operate correctly. Fresh-water rinsing can help remove salt and dirt; follow the rope manufacturer's care guidance where deeper cleaning is required.
Professional splicing can provide a compact termination where it is appropriate for the rope and application. See our Yacht Rope Splicing Guide.
Running Rigging for Cruising & Racing
Cruising yachts commonly prioritise durability, handling and value. Polyester double braid is therefore used extensively, although low-stretch core ropes may be chosen for particular halyards or controls.
Performance and racing yachts often place greater emphasis on low stretch, reduced weight and precise sail control. Dyneema-core constructions are frequently used where those characteristics justify the additional cost.
Neither approach means every rope on the yacht needs to use the same construction. Running rigging can be specified line by line according to its job.
How Much Does Replacement Running Rigging Cost?
The cost depends on the number of lines being replaced, their finished lengths and diameters, rope construction, splicing and any fittings required.
For an indicative model-specific starting point, use our Yacht Rigging Database & Cost Guide. If you would like our riggers to prepare a specification, request a rigging estimate.
Running Rigging FAQs
What is the difference between a halyard and a sheet?
A halyard raises or lowers a sail. A sheet controls the sail's angle and trim once it is set.
How often should running rigging be replaced?
There is no universal calendar interval. Inspect each line for wear, damage and changes in performance and replace it when its condition or service requirements justify doing so.
Can polyester and Dyneema be used on the same yacht?
Yes. Different lines can use different constructions depending on their load, stretch, handling and durability requirements.
How do I know what diameter and length I need?
Use the existing correctly specified line as a starting point, check compatibility with the yacht's hardware, or use our model-specific Yacht Rigging Database. Our riggers can also help where the specification is uncertain.
