Running Rigging & Splicing for Sailboats
Running rigging is everything that moves on a sailboat: halyards, sheets, control lines, reefing lines, traveller and outhaul lines. It's also the part of the boat most cruisers ignore until something parts at an inconvenient moment. Halyards in particular live in the sun and salt 365 days a year — they need attention.
This guide covers when to replace, what it costs, where to find the work, and which lines deserve specialist attention versus DIY.
What running rigging includes
- Halyards: Main, headsail, spinnaker. The high-stress, high-UV-exposure lines.
- Sheets: Main, jib, spinnaker. Moderate stress, frequent hand contact.
- Control lines: Boom vang, traveller, outhaul, reefing lines. Often led aft through clutches.
- Lazy jacks, topping lift, downhaul: Lower priority but worth checking.
When to replace
Annual inspection. Replace when you see:
- Significant chafe at clutches or sheaves
- Broken yarns visible through the cover
- Hard spots in the core (often from heat damage in clutches)
- Severe UV fading or stiffness
- Cover slippage over the core
Halyards in tropical use commonly need replacement at 8–10 years. Sheets last longer but bear more chafe. Anything older than 12 years is on borrowed time regardless of appearance.
What it costs
| Item | Common range (USD) | Notes |
|---|---|---|
| Mainsail halyard (40 ft) | $180–320 | Dyneema cover, 50 m |
| Genoa halyard | $200–350 | Slightly longer length |
| Mainsheet | $120–220 | Double braid polyester |
| Jib sheets (pair) | $140–240 | Double braid polyester |
| Full set replacement (materials) | $1,500–2,800 | 40-foot cruising boat |
| Splicing labour (rigger) | $300–600 | Full set |
| DIY tools (fid set + manuals) | $80–150 | One-time |
DIY or hire it out?
Splicing is teachable. Double braid eye splice is the trickiest and takes practice; Dyneema splicing is easier. Most cruisers who own their boat for years end up learning at least the basic splices because the savings over rigger labour are meaningful.
Hire a rigger for: Mast inspections, halyard runs that require going aloft, anything involving wire-to-rope splices, swaging, hydraulic systems.
Frequently asked questions
When should I replace halyards?
Annually inspect. Replace at significant chafe, broken yarns, hard spots, or severe UV damage. 8–10 years typical in tropical use.
What's the cost?
Full set materials $1,500–2,800 for a 40-footer. Add $300–600 if hiring a rigger to splice.
Can I do it myself?
Yes for most lines. Splicing is teachable; online tutorials cover everything.
Dyneema vs polyester?
Dyneema for halyards (light, low stretch). Polyester for sheets and control lines (cheaper, better hand).
Where to get it done?
Most cruiser hubs have a rigger. Annapolis, Fort Lauderdale, Newport, Lagos, Las Palmas, Marmaris all have multiple.
