A coeliac crew member changes how you cruise. So does a vegan, a serious nut allergy, or anyone who genuinely cannot eat what the boat happens to have. I found this out when my wife was diagnosed coeliac between one season and the next, and the easy French routine of bread, pastry and "we will sort it ashore" suddenly needed a rethink. The good news is that France handles special diets far better than its reputation for butter and gluten suggests. The catch is that the help clusters in towns, and a boat does not always land in a town.
The labels that actually mean something
France regulates dietary labelling tightly, which is a gift to a worried shopper. A product marked "sans gluten" must contain less than 20mg of gluten per kilo, the same threshold used across the EU. The certified mark to look for is the crossed grain symbol, called the epi barre in French, a clear sign the maker has been audited rather than just hopeful.
For vegetarians and vegans the word is "vegetarien" or "vegan", and the V-Label is increasingly common on packaging. "Bio" means organic and certified, not dietary, but bio shops are where the free-from ranges concentrate, so the word is a useful signpost even if it does not answer your question directly.
Learn these words before you need them. The difference between asking confidently for "sans gluten" at a counter and miming a wheat allergy is the difference between a meal and a gamble. The shopping vocabulary you need is set out in french shopping vocabulary.
France also runs strong allergen labelling on packaged food, the same 14 declared allergens used across the EU, listed in the ingredients in bold or otherwise highlighted. Gluten, nuts, milk, eggs, soya, fish, crustaceans and the rest are called out clearly, so a careful reader can shop a French supermarket with real confidence once they know the French words for what they are avoiding: ble (wheat), lait (milk), oeuf (egg), fruits a coque (tree nuts), arachide (peanut). Restaurants are required to be able to tell you about allergens too, though on a boat you will be cooking far more than eating out, so the supermarket label is what matters most day to day.
Where the free-from food lives
Every major supermarket chain now carries a free-from aisle. Intermarche, Carrefour, Leclerc, Auchan, Monoprix, Casino and Systeme U all stock a "sans gluten" range, usually grouped together rather than scattered, often near the organic section. The range in a small village Carrefour Express is thin. The range in a hypermarket on a town ring road is genuinely good.
Better still are the bio chains. Naturalia, Biocoop and La Vie Claire run dedicated organic shops, and they carry the widest free-from and plant-based ranges in the country. The reassuring fact for a cruiser is that nearly every decent-sized French town has at least one bio store, so a landfall near a town of any size usually means a proper shop within walking or cycling distance of the pontoon.
The honest warning is about the in-between landfalls. A small fishing port or a remote anchorage may have one tiny epicerie and nothing else. If your crew has a hard dietary need, you cannot rely on those places, and you must carry enough to bridge them.
It helps to scout ahead. Before a leg I look up what is actually within walking distance of the next harbour rather than assuming, because a town that looks substantial on the chart can turn out to be a single bakery and a bar. A quick check on a maps app or a cruising app like BoatMap, which lists what is near each harbour, tells you whether the next stop has a real supermarket or only the postcard-pretty nothing. For a crew with a coeliac or a serious allergy aboard, that five minutes of research is the difference between a relaxed stop and a hungry one.
Provisioning to bridge the gaps
The principle is the same as carrying water: stock for the worst stretch, not the average. Before a leg that takes you away from towns, I do a deliberate special-diet shop at the best supermarket or bio store I can reach, and I overbuy on the things that are hard to find.
What I now keep aboard as standing stock for a coeliac crew:
- Gluten-free pasta and a couple of bags of rice, which keep indefinitely and cover most dinners.
- Certified gluten-free crackers or oatcakes to replace the baguette that the rest of the crew lives on.
- A jar of stock and sauces checked for hidden wheat, because that is where gluten ambushes you.
- Gluten-free flour or a packet mix, so that when the boulangerie run is off the table the coeliac still gets something bread-shaped.
The hidden-wheat problem is the one that catches people out. It is not the obvious bread that gets a coeliac, it is the stock cube, the soy sauce, the thickened sauce, the dusting of flour on a supermarket charcuterie. On a boat you control this completely by cooking from raw ingredients, which is the safest way to feed a coeliac anyway. Buy the fish, the vegetables, the rice and the olive oil, and you sidestep almost every ambush. The cooking, kept simple, is the same good galley cooking the whole crew eats, just without the bowl of pasta swapped for the gluten-free one.
For vegetarians and vegans, France is easier than it looks once you lean on what the markets already sell. The produce is superb, pulses and tinned beans are everywhere, and a market haul of vegetables, olive oil, garlic and herbs makes meals nobody thinks of as compromise food. Turning that haul into proper dinners is the subject of cooking aboard french market produce. The thing to carry is plant protein that the small shops lack: dried lentils, chickpeas, and UHT plant milk, none of which need a fridge.
The honest difficulty for vegans in France is the cheese-and-butter culture, not the supermarket shelf. A village restaurant may struggle to feed a vegan well, where it can usually rummage up something for a vegetarian. So a vegan crew cooks aboard more, which on a cruise is no hardship and often cheaper anyway. Stock the boat at a Naturalia or Biocoop at the start, carry your own plant milk and protein, and treat the markets as the source of everything fresh. Lentils with market tomatoes, garlic and herbs, or a chickpea stew, feeds a crew for a couple of euros a head and tastes of the place you bought it.
A diet that is a preference rather than a medical need gives you more room to improvise, and the markets reward improvisation. A diet that is medical, a real coeliac or a real allergy, gives you none, and you plan it like a passage: stock for the gaps, read every label, never assume the small port will save you.
The pharmacy and the doctor, just in case
A French pharmacy, marked by the green cross, is more clinically capable than a British chemist and worth knowing about if a diet shades into a medical need. Pharmacists can advise, stock some specialist nutritional products, and point you to a doctor. If someone aboard has a severe allergy, carry the prescribed adrenaline auto-injectors in date and in number, because replacing them on a cruise is slow and uncertain. France runs a 15 number for medical emergencies and 112 across the EU, both worth having written by the chart table.
A diet does not have to shrink the cruise
The fear with a special diet is that it turns France into a country of things you cannot have. In practice it turns into a country of markets, bio shops and careful timing, which is not a bad way to cruise anyway. We eat better now than before the diagnosis, because we buy fresh, cook aboard and plan the shops properly. The teenagers still get their pastries from the boulangerie each morning, a ritual covered in breakfast french port, and nobody goes without. The work is in the planning, done at the dock before the gaps appear, not in the panic of an empty locker off a town that shut at noon.
