A friend's husband had a suspected stroke aboard their boat off the Brittany coast a few seasons back. The French coastguard lifted him off by helicopter, the hospital in Brest was superb, and three weeks later the problem was the bill nobody had thought about: getting him home. A medical flight back to the UK, with a doctor, a nurse and the airline seats they had to block, came to a number that made their eyes water. They were lucky. Their policy paid. Plenty do not, because of a single line buried in the small print that they had never read.
This is the least glamorous insurance you will ever buy and the one most likely to save your finances. Here is how it works and how it goes wrong.
The two things being insured, which are not the same
People muddle these constantly. Medical evacuation, medevac, is getting you from where you are hurt to somewhere that can treat you: the helicopter off the boat, the air ambulance from a small clinic to a major hospital. Repatriation is getting you home afterwards, whether that is a stretcher flight, an escorted scheduled flight, or in the worst case the return of remains.
They are separate events with separate costs, and a policy that covers one does not automatically cover the other. Read your schedule for both words.
The numbers, because they are frightening
This is where complacency dies. Emergency medical transport is genuinely expensive, and the figures below are the realistic range from the insurance industry, not scare stories.
A helicopter evacuation averages around the equivalent of 35,000 to 40,000 euros, and a full international air ambulance can reach 100,000 euros and beyond. One documented evacuation from Nice to Paris, a short hop within France, came to 12,900 euros. A long-haul air ambulance from outside Europe has hit 228,000 euros. A stretcher repatriation flight home typically runs 25,000 to 30,000 euros once you count the multiple airline seats a stretcher case blocks out.
Against that, the cover itself is cheap. The industry guidance is to hold at least 100,000 to 250,000 euros of evacuation and repatriation cover for international travel, more for remote or adventurous use. Buying that limit costs a fraction of a single uninsured flight.
The reciprocal card will not save you here
British and EU sailors lean on the reciprocal health card, and rightly so for treatment. But the GHIC and EHIC cover state medical care inside the system. They do not pay to fly you home, they do not cover a private air ambulance, and they do not cover the costs of a death abroad. The card and the insurance do different jobs, and the gap between them is exactly the gap that costs five figures. I set out what the card does and does not do in health entry rules for France in 2026, which is worth reading alongside this.
The clause that voids your cover: where the water starts
Here is the trap that catches boaters specifically. A standard travel policy, the kind that comes with a bank account or a cheap annual multi-trip, typically covers you on land and within a short distance of the shore. The moment you are on a passage, more than a defined number of nautical miles offshore, or sailing at night, or single-handed, the cover can simply stop. Some policies draw the line at 12 nautical miles, some at the territorial limit, some exclude "sailing as a means of transport" altogether.
So a heart attack on the beach at Hyeres is covered, and the identical heart attack twenty miles offshore on the same trip is not. That is not a loophole the insurer is hiding to be cruel; it is the difference between holiday risk and marine risk, and they price them separately.
What you need depends on what you actually do:
- Coastal day-sailing within a few miles of port: a good travel policy with a clearly stated watersports or sailing extension may be enough. Read the distance limit.
- Offshore passages, Channel crossings, the Bay of Biscay: you need a policy that explicitly names offshore or coastal racing and cruising, often with a stated mileage band. A Channel crossing is the obvious example, and the cold-water risk that makes a fast lift-off so important is in hypothermia and cold-water risk in the Channel.
- Liveaboard or long-stay: an annual or expatriate medical policy with strong evacuation and repatriation limits, because a single trip policy will run out and your time in France is now precisely counted by the new border system.
Single-handed and night sailing: read this twice
If you sail alone, or routinely at night, dig out the exact wording. A great many personal accident and travel policies exclude or limit single-handed sailing and night passages, on the reasonable grounds that the risk profile is different. If that describes you, you need a specialist marine policy that says so in writing. Do not assume; phone the insurer and get the answer by email.
The other wording trap is the pre-existing condition. Insurers will refuse a claim, even a genuine and unrelated one, if you failed to declare a condition you had been treated for or warned about before you bought the policy. The rule of thumb is to declare everything and let them price it. A declared heart condition costs a bit more in premium; an undeclared one costs you the entire claim at the worst possible moment. The same goes for age limits and medication: many cheap policies quietly cap cover at a certain age or exclude conditions controlled by certain drugs, and the cap is in the small print, never the headline. Spend the extra hour reading it. The flight home you are insuring against is the most expensive thing that can happen on a cruise, and it is no time to discover a clause you skimmed.
How an evacuation actually happens off France
It helps to know what you are insuring against. Offshore, you do not dial 999 or a private ambulance. You raise the CROSS, the French coastguard, on VHF channel 16, and for a medical problem they connect you to the CCMM in Toulouse, the national telemedical service staffed by emergency physicians. The doctor assesses your patient over the radio and decides whether the situation can be managed on board or needs an evacuation. If it does, the coastguard tasks a helicopter or a lifeboat, the SNSM. The rescue itself, the lift-off, is not what you pay for. What you pay for starts at the hospital door and runs all the way to your own front door. The full procedure for raising that help is in a medical emergency at sea in France.
A buying checklist that has saved me money and worry
- Confirm both medevac and repatriation are covered, by name, on the schedule
- Confirm a limit of at least 100,000 euros, ideally 250,000 for offshore or long trips
- Find the offshore distance limit and check it covers your actual passages
- Check single-handed and night sailing are not excluded if you do either
- Check the policy covers a 24-hour assistance line that arranges the flight, not just reimburses it later, because you will not have 30,000 euros to front
- Declare every pre-existing condition honestly; an undeclared condition is the commonest reason a genuine claim is refused
- Keep the assistance number and your policy reference somewhere the crew can find them without you, taped inside a locker
The borders into France have tightened for 2026, and the day-counting is stricter than ever, which I cover in health entry rules for France in 2026. But the rule that has not changed, and never will, is this: the sea will occasionally hurt someone aboard, the French will come and get you, and then you will need a way home. Buy that way home before you leave the dock. It is the cheapest peace of mind in sailing.
