Independent guide: Offshore preparation is safety-critical. Work with a rigger who understands your passage plan, and check any race or rally safety requirements.
Quick answer
A bluewater rig must survive thousands of miles of continuous loading, far from help. That changes priorities: start with a rig of known age and condition, add redundancy (an inner forestay, running backstays, a second halyard for every sail), choose fittings that can be repaired at sea, manage chafe relentlessly, and carry the spares and tools to rebuild a stay. Plan the rig work early enough to sail it hard before departure.
Offshore rig priorities
- Known history. A documented re-rig within a few years, or a thorough inspection.
- Redundancy. Spare halyards, an inner forestay or cutter stay, and a way to jury-rig.
- Serviceability. Mechanical terminals and common wire sizes that can be sourced abroad.
- Chafe control. Offshore, lines rub for days on end; chafe kills more running rigging than load.
- Inspection at sea. A routine to go aloft or use binoculars daily, and check deck fittings.
Popular offshore rig upgrades
| Upgrade | Why |
|---|---|
| Inner forestay / cutter stay | Storm jib or staysail on a dedicated stay |
| Running backstays | Support for the inner stay and upper mast |
| Mechanical terminals | Repairable anywhere |
| Dyneema halyards and spare halyards | Less stretch, redundancy |
| Mast steps or ladder | Safer inspections aloft |
| Twin downwind poles | Trade-wind sailing |
| Storm trysail track | Independent of the mainsail track |

Pre-departure rigging plan
- mast-out service and re-rig or detailed inspection — see mast-out rig service
- chainplates pulled and inspected on older boats
- furler service and spare furling line
- new lifelines and jackstays
- full running rigging review
- shakedown sail in 20+ knots, then re-tension
See the offshore passage rigging checklist.
Emergency preparation
Carry cutting tools capable of cutting the rig free, and know how to rig a jury stay. See emergency rigging repairs and how to make an emergency rig repair.
Regulatory context
Offshore races from Australia set safety requirements through the Australian Sailing Special Regulations and event documents. Cruising yachts have no single equivalent standard, which puts the responsibility on the skipper.
Frequently asked questions
Should I re-rig before an ocean passage?
If the rig's age is unknown, it is approaching or past about ten years, or an inspection has found issues, many sailors re-rig before departure so the rig starts the passage with a known history. The timing should leave room for a shakedown sail and re-tensioning before leaving.
What rigging spares should I carry offshore?
Common spares include a length of wire equal to the longest stay with mechanical terminals to suit, spare clevis pins, split pins and rings, toggles, shackles, Dyneema line for lashings and emergency stays, rigging tape, and bolt cutters or a hydraulic cutter capable of cutting the rig free.
Why do bluewater sailors prefer mechanical terminals?
Mechanical terminals can be assembled with hand tools on board, re-used with new internal parts and disassembled for inspection. That means a damaged stay can be rebuilt at sea or in a remote port without a swaging machine.
