The bang was not loud. That is the thing people get wrong when they imagine rigging failure: they expect a crash. What we got, twenty miles off the Brittany coast, was a flat metallic clack and then the mast doing something masts should never do, leaning a few degrees to leeward and quivering. The cap shroud's lower swage had let go. We had perhaps a minute, maybe less, to keep the rig standing, and most of what saved it was decided in the first ten seconds.
Rigging failure at sea is one of those emergencies where the right reflex matters more than the perfect plan. The plan can come once the mast is safe. This is what I learned doing it for real, backed by what the riggers and sailmakers say, written for visitors making passages along the French coast where the next harbour might be a few hours away rather than minutes.
The first move: take the load off, the right way
Every shroud and stay holds the mast against a load coming from a particular direction. The instant something fails, your job is to remove the load that was being carried by the broken piece. Which way you turn depends on what went.
- If a cap shroud or upper shroud fails, it was supporting the mast against the pull of the sails on the opposite tack. Tack or gybe immediately to put the load onto the rigging that is still intact. If the starboard shroud goes while you are on starboard tack, you have very little time, and tacking is the move. Hesitate and the mast comes down.
- If the forestay fails and you are close-hauled, bear away downwind at once. Counter-intuitively, do not touch the headsail if it is still set on the foil, because that sail may now be the only thing holding the masthead forward. The backstay and the sail together can keep the rig up long enough to act.
- If the backstay fails, head up into the wind to let the forestay and headsail take the strain forward.
Once you have turned the boat to unload the failure, get the sails down and the engine on. The corrective action is temporary and the rig is living on borrowed time, so reduce everything that is loading it.
Save the mast if you can
A standing rig is a system, and a single failed wire can often be bridged. The classic save is a spare halyard. A main or spinnaker halyard led to a strong point on the relevant side, and tensioned hard, can substitute for a lost shroud well enough to motor home. Led to the stemhead, a halyard can stand in for a lost forestay. It will not be as stiff as the original wire, so keep the loads gentle, motor rather than sail if you can, and pick the flattest water.
This is where preparation pays. The smallest components cause the biggest dramas: a clevis pin of the wrong size, a missing split pin, a tired swage. Insurers do not mandate a replacement interval for standing rigging, but they expect evidence that it was checked and maintained by someone competent at sensible intervals, and a dismasting claim with no maintenance history is an awkward conversation. A rig that is regularly inspected, with every split pin present and taped, is a rig that fails far less often.
When the mast comes down anyway
Sometimes you lose it. The priorities then change in order: people first, then the hull, then the rig.
Account for the crew and check no one is hurt by flailing wire or falling spar. Then protect the hull, because the single greatest danger after a dismasting is the broken mast and boom punching a hole in the topsides as the boat rolls. The rig becomes a battering ram alongside.
Decide whether to save the spar or cut it away. If the sea is moderate and you can lash the mast alongside without it holing the boat, you may recover thousands of euros of gear. If it is holing you, cut it loose. A hacksaw will go through a wire stay, but bolt croppers or a cordless angle grinder are far faster, which is why both belong aboard for offshore work. Beware: rigging under tension whips unpredictably when cut, so keep faces and hands clear and cut the leeward, less-loaded wires where you have a choice.
Once the rig is clear, set up a jury rig if you have the means: a boom or spinnaker pole lashed upright as a stub mast, a storm jib or trysail set from it, enough to give steerage and a little drive towards the coast. France has the advantage of a close coastline with frequent ports, so a modest jury rig and the engine will usually get you in.
The tools and spares that decide the outcome
Whether a failure stays a nuisance or becomes a dismasting often comes down to what is in your locker. The kit is cheap relative to a new rig, and most of it lives in a small bag.
- Bolt croppers and a cordless angle grinder with spare discs. A hacksaw works but is desperately slow when a rig is pounding the hull, and minutes matter.
- A serious knife and a pair of heavy gloves, because handling failed wire under load will shred bare hands.
- Spare clevis pins and a generous supply of split pins and rings in the sizes your boat uses, plus a few bulldog grips and short lengths of wire or high-modulus rope for emergency stays.
- A roll of self-amalgamating tape and rigging tape to dress sharp ends and stop spare halyards chafing through.
Just as important is knowing your own rig before anything breaks. Walk the deck and note which halyard reaches which corner, where the strong points are for a jury stay, and which shroud carries the load on each tack. The crews who cope are the ones who have already rehearsed the moves in their heads, so that when the swage lets go the hands move before the brain has finished panicking.
Getting to a French port
A disabled rig rarely means a disabled boat. With the engine running and the wreckage controlled, you can usually motor to shelter. Plan the route to the nearest realistic harbour with sea room to spare and the wind and sea behind you if possible, the same lee-shore discipline that applies in any emergency on this coast, which our guide to escaping a lee shore in the Bay of Biscay covers in detail.
If you cannot make port under your own power, or the situation is deteriorating, call CROSS on VHF channel 16. A boat that is disabled but not in immediate danger is a Pan-Pan, not a Mayday, and our guide to the French distress and safety call procedure sets out the wording. Remember the cost structure: rescue of life is free under the 1979 SAR convention, while towing a safe but disabled boat is a paid service, with the SNSM typically invoicing between 340 and 700 euros depending on the boat and the means. If you can limp in yourself, you save the bill and the favour.
After the failure
Once you are tied up, resist the urge to call it fixed because the boat floats and the engine runs. A failure in one part of the rig usually means the rest is the same age and under the same neglect, so a full rig inspection by a qualified rigger before you sail on is not optional. French ports along the coast carry chandlers and riggers, and major centres can re-rig a boat, though parts for a foreign spar may take time to arrive.
There is also a buying lesson here. The standing rigging is one of the systems that separates a sound secondhand boat from an expensive one, and the same scrutiny applies as in our guide on used sailboat hull inspection. Tired wire, mismatched pins and undocumented age are warning signs whether you are buying or maintaining.
We saved that mast off Brittany with a spare halyard winched to the toerail and motored into a Breton harbour with the boom lashed for support and our nerves shredded. The repair was a day's work and a few hundred euros. The lesson was cheaper still and free to learn: check the small parts, carry the tools to cut a rig free, and rehearse in your head which way you turn the boat before the day the wire lets go.
