How Cruisers Jury-Rig Rudders, Rigs and Keels During Emergencies
An updated how-to consolidates emergency fixes for rudders, rigs and keels, stressing prevention, specific kit and simple jury rigs that get you home when primary systems fail.

A practical how-to lays out prioritized steps for three failure modes that can end a cruise: rudders, rigs and keels. Prevention tops the list: haulout inspections and routine checks of standing and running rigging reduce the chance of a catastrophic failure, and a clear plan plus the right tools turn a nightmare into a manageable problem.
Rudder loss and steering failure are the clearest emergencies. Sailors are warned that a rudder can fail in several ways, with rudder stock failure often occurring just below the lower bearing on spade rudders where bending loads concentrate. When the rudder separates, a boat will rotate about its center of lateral resistance. Fin‑keel boats are at special risk of abrupt rotation and broach with sails up. Practical countermeasures range from emergency tillers to improvised control surfaces. “Every boat should carry an emergency tiller and know how it works,” the guidance states. An emergency tiller usually fits into the rudder stock through an inspection port and may require removing the wheel. Installing a tiller will likely keep the rudder straight, but steering will typically require rigging control lines from the tiller to blocks on each rail and leading them to winches.
When the rudder is gone entirely, crews have used drogues, warped sails and improvised boards to steer. SV EOTI’s experience captures the stakes: “The nightmare scenario is losing the rudder entirely... Survival on a boat is about knowing these steps, practicing them, and never trusting that the ocean will wait while you figure it out.” One dramatic example saw the Blue Jacket 40 Bailiwick, after losing a carbon fiber rudder post, lash a bulkhead panel to a whisker pole to act as an oar‑like rudder during the Bermuda Race.
Rigging failures are described as “like broken shoelaces.” Replacement is ideal, but when you must jury‑rig, use methods stronger than a knot. Recommended shop and deck tools include Swiss‑made Felco wirecutters, a Nicropress crimper for swaging wire‑rope fittings, and eye protection that fits over glasses. Carry a supply of spare blocks and cleats and a long length of Dyneema the diameter of steering cables as a lightweight, space‑saving backup for broken steering wire. Improvised barber haulers, new blocks, and swaged wire assemblies let you restore critical control long enough to get to port.
Bridles, drogues and sea anchors require thoughtful lead runs for control. Bridle lines must be led to cockpit winches so you can trim the device and influence heading. Gudgeon lines used to haul a spar into place make deployment in a seaway easier, but expect chafe; check and repair such lines frequently.
The tone of the practical guidance is pragmatic: accept temporary fixes long enough to reach repairs. “Losing steering is an emergency, but it’s one that you can prepare for by having a plan tucked away in the back of your head,” the how‑to reminds cruisers, and “all we’re trying to do is get home, not win the race.” For every cruiser that means inspect steering and rigging regularly, carry an emergency tiller and Dyneema backup, pack Felco cutters, a Nicropress crimper and goggles, keep spare blocks and cleats aboard, and practice the deployments at sea. Those simple investments and rehearsals are what make improvised solutions survivable rather than desperate.
