Independent guide: Lifeline rules for racing are set by Australian Sailing's Special Regulations and event documents. Always check the current version for your category.
Quick answer
Lifelines — also called guardwires — run between the pulpit, stanchions and pushpit to keep crew aboard. They are replaced when the wire, terminals, lashings or covers show wear or corrosion, or when the boat must meet racing safety requirements. Stainless wire with swaged terminals is traditional; Dyneema is increasingly common. Racing yachts must meet the lifeline requirements in the current Australian Sailing Special Regulations for their category.
Inspecting lifelines
- look along the full length of wire for broken strands and rust
- check swages for cracks and rust weeping at the neck — see swaging
- check lashings at the ends for chafe and UV damage
- check gate hooks, pelican hooks and their pins
- check stanchion bases for cracks and leaks
- check synthetic lines for UV fading, fuzzing and chafe where they pass through stanchions
Wire versus Dyneema
| Stainless wire | Dyneema / synthetic | |
|---|---|---|
| Inspection | Visible along length (if uncoated) | Visible, but UV and chafe need watching |
| Weight | Heavier | Much lighter |
| Chafe at stanchions | Resistant | Needs protection or a suitable cover |
| Lifespan | Long if uncoated and well maintained | Shorter; UV-dependent |
| Racing rules | Widely accepted | Accepted in many categories with conditions |
Lifelines by boat type
- Racing yachts: lifeline height, diameter, material and lashings are inspected by safety auditors under the Special Regulations.
- Bluewater yachts: lifelines are also jackstay and grab points; strength and security of attachments matter.
- Catamarans: long runs along each hull, often with netting at the bows.
- Charter yachts: commercial operation brings AMSA requirements into play.
- Liveaboards: lifeline netting for children and pets changes load and chafe patterns.
The replacement job
A rigger measures each run from pulpit to pushpit, fabricates the new lines with swaged or spliced ends, fits gates and lashings, and tensions the run. Many owners replace lifelines during a re-rig or before an offshore season. See the offshore rigging checklist.
Frequently asked questions
How often should yacht lifelines be replaced?
There is no single interval. Replace lifelines when inspection shows broken strands, cracked or rusting swages, damaged covers hiding the wire, worn lashings or UV-degraded synthetic line. Plastic-covered wire should be treated with caution because corrosion hides under the cover.
Are Dyneema lifelines allowed for racing in Australia?
Synthetic lifelines are permitted in many racing categories subject to specific requirements, but the rules differ between categories and change over time. Check the current Australian Sailing Special Regulations for your category and the notice of race before replacing lifelines on a racing yacht.
Why is plastic-coated lifeline wire discouraged?
The plastic cover traps moisture against the stainless wire and hides corrosion and broken strands, so a lifeline can look sound while being weakened underneath. Uncoated wire can be inspected along its whole length, which is why many safety rules restrict or prohibit coated wire.
