The first time I needed a doctor in France, I was tied up in Saint-Malo with a chest infection that had been quietly brewing since the Channel crossing. I had a GHIC card in my wallet and only the vaguest idea of what it would actually do for me. It turned out to do quite a lot, and also rather less than I had hoped. Here is what I have learned in the years since, on a card that every UK boater cruising France should carry but very few understand.
What the GHIC actually is
The GHIC, the UK Global Health Insurance Card, replaced the old EHIC for British residents after Brexit. It gives you access to state-provided healthcare in EU countries, including France, on the same terms as a French resident. That is the key phrase: same terms as a local. A French resident does not get healthcare for free, and neither do you. They pay up front, claim most of it back, and you are in exactly the same boat.
The card is valid for five years from the date of issue. Check the expiry before you cross, because a card that runs out while you are halfway down the Biscay coast is useless, and you cannot renew it from a French marina with a flat data connection. Renewing is free and takes about five minutes on the official NHS site at nhs.uk/ghic. Anyone charging you for a GHIC is running a scam, so ignore the copycat sites that sit above the real one in search results.
What it covers, what it does not
The GHIC covers treatment that becomes medically necessary during your stay. Think a GP visit for the chest infection I had, emergency hospital treatment after a galley burn, or ongoing care for a chronic condition such as dialysis arranged in advance. It also covers routine maternity care, as long as you have not travelled specifically to give birth.
What it does not cover is the part that catches sailors out. It will not pay for repatriation. If you break a leg falling off the pontoon and need flying home, the GHIC contributes nothing to that cost, which is exactly where a marine medical bill turns frightening. It is not accepted at private clinics, only the public system. And it does not cover treatment you came to France to receive, so no using it for a planned hip operation on the cheap.
This is why every official source repeats the same line: a GHIC is not a substitute for travel insurance. For the bigger picture on cover, read my guide to medical insurance cruising France, because the two work together rather than one replacing the other.
One more limitation that bites sailors specifically: the GHIC covers state healthcare in the country you are in, not the act of getting you there. Anchored off a remote stretch of the Atlantic coast, you may be a long taxi or ambulance ride from the nearest hospital, and the GHIC does not pay for the journey. It is a reimbursement card for treatment received, nothing more. Picture it as a discount on the bill, not a safety net for the whole event, and you will set your expectations correctly.
The costs you still pay
Here is where being treated as a local matters. A standard GP consultation with a sector 1 doctor in France is fixed at 30 euros as of 2025. The French state reimburses 70 percent of that, leaving you with 9 euros plus a small flat patient contribution that rose from 1 euro to 2 euros. For children under six, the consultation is 35 euros. None of these are large numbers, but you pay them at the counter and reclaim afterwards, which means carrying enough cash or a working card.
Prescriptions work the same way. There is a per-pack levy of 50 centimes on each box of medicine dispensed, capped at 50 euros per person per year. Reimbursement on the medicine itself runs at four levels, 15, 30, 65 or 100 percent, depending on the drug. A 20 euro medicine reimbursed at 65 percent gives you 12 euros back. The system is generous by international standards, but the cash flow runs the wrong way for a visitor: you pay first, claim later.
How reimbursement works for a visitor
This is the bit nobody explains. As a visitor on a GHIC you usually pay the doctor or pharmacy in full, then submit a claim. The form is the S3125, the Soins recus a l'etranger claim, which you send to the NHS Overseas Healthcare Services on your return with the receipts (the feuille de soins the doctor gives you, and the prescription receipt from the pharmacy). Keep every piece of paper. A crumpled feuille de soins lost in a wet oilskin pocket is a claim you cannot make.
Some pharmacies and surgeries that see a lot of tourists will process the GHIC directly through the French system, sparing you the up-front payment, but do not count on it in a small Breton port. Assume you pay, assume you claim later, and you will never be caught short.
There is a time limit on claims, so do not let a season's worth of receipts gather mould in a chart-table drawer. Submit the S3125 reasonably promptly after you are home, and keep copies of everything you send, because the original receipts go off into the system and you want a record if anything goes astray. The reimbursement comes back in sterling, calculated from the French regulated rates, which is another reason to keep the doctor in sector 1 where the fee is the fixed 30 euros rather than a sector 2 doctor free to charge more.
The card is per person, and children need their own
This trips up families every season. The GHIC is individual. Every member of the crew, every child, needs a card in their own name with their own number. A parent's card does not extend to the kids. Order them all together on the NHS site, and order the children's a few weeks ahead because they sometimes take longer to verify. I keep the whole family's cards in a single waterproof sleeve with the ship's papers, and a photographed set on my phone, so that losing one wallet does not leave anyone uncovered.
It is also worth knowing that the GHIC follows you across the EU, not just France. If your French cruise turns into a hop down to Spain or across to Italy, the same card works on the same principle in those countries, each with its own local rates and reimbursement quirks. The card is a Schengen-wide tool, which makes it doubly worth keeping valid if your plans are loose.
Practical advice from the pontoon
A few things I now do as routine before any season in France:
- Photograph both sides of the GHIC and store the image somewhere you can reach offline, in case the card goes overboard with the wallet.
- Carry a small float of euros in cash specifically for medical use, because a remote pharmacy may not take a foreign card.
- Keep a note of your usual prescriptions in French generic names, since French pharmacists dispense by molecule, not by UK brand.
When you do need to find treatment, knowing the practical routine of seeing a doctor in a French port saves a lot of fumbling, and if the problem starts offshore rather than alongside, the rules change entirely, which is why I keep a separate mental checklist for a medical emergency at sea in France.
The honest summary
The GHIC is a genuinely useful card. It turns a frightening foreign healthcare system into something close to what a French citizen pays, which is to say affordable for routine illness and injury. But it stops dead at the big risks: repatriation, private treatment, anything that needs you flown home. Treat it as the floor of your cover, not the ceiling. Carry it, keep it valid, photograph it, and then put proper insurance on top. The card cost me nothing and saved me real money in Saint-Malo. The insurance I have never claimed on is the one that helps me sleep.
