If orcas interact with your boat

This is a summary of the published GTOA and maritime authority recommendations. Conditions and official advice evolve: read the current GTOA recommendations and always follow instructions from the authorities on scene.

1. Stop the boat. Drop sails or stop the engine as conditions allow. Interactions tend to be shorter when the boat is not fighting back.
2. Hands off the wheel or tiller. The rudder is the target; holding it risks injury and worse damage.
3. Stay low, stay quiet. Keep the crew away from the rudder area and avoid leaning over the side.
4. Alert the authorities. VHF channel 16 or 112. Tell them your position and situation.
5. Do not touch, feed or throw anything at the animals. They are a critically endangered population and protected by law.
6. Report it afterwards (GT orcas app or the CA portal), including uneventful passages. The maps are only as good as the reports behind them.

What is actually happening (the short version)

Since 2020, a small subgroup of the critically endangered Iberian orca population (about 15 individuals out of roughly 50) has been physically interacting with boats, mostly pushing and biting rudders on sailing boats under 15 metres. Hundreds of interactions have been recorded; a small number of boats have been sunk. Researchers do not fully agree on the cause: the leading hypotheses range from play behaviour spreading through the pod to a learned response. What matters for a skipper is not the why, it is the where and the when, which is what the live maps answer.

Orca season passage prep: the checklist

Beyond the live maps, this is what experienced crews sort out before transiting the affected coast. Most of it is the boring paperwork and gear that only matters when something goes wrong:

• Steering spares and emergency tiller: confirm you have them and know how to fit them at sea. Rudder damage is the most common outcome of an interaction.
• Safety gear in date: liferaft service, flares, EPIRB battery, lifejackets. If you end up in the water or under tow, this is what counts.
• Insurance check: confirm your policy covers rudder damage and towing on this stretch of coast, and know the claim contact.
• Documents reachable: registration, insurance and crew documents accessible from your phone, not only in a drawer aboard.
• Comms ready: VHF checked, 112 and the local MRCC numbers saved, and the GT orcas app installed before you lose signal.
• Passage plan with options: know the shallow-water routes (interactions concentrate in deeper water) and the ports of refuge along your leg.

FAQ

When is the season?

Interactions happen year round but concentrate between May and September, moving with the tuna migration: typically the Strait of Gibraltar in early summer, then north along the Portuguese and Galician coast.

Does this affect motor boats?

Rarely. The overwhelming majority of reported interactions involve sailing boats under roughly 15 metres.

Is anywhere lower risk?

Reported interactions concentrate in deeper water; many skippers route inside the 20-metre contour where practical on affected stretches. That is a pattern in the data, not a promise: check the current maps and make your own passage decisions.
