Forty-five euros in La Rochelle. Around a hundred and forty in Saint-Tropez in August, for the same 12-metre boat, on the same night. That gap is the whole story of cruising France, and most visitors only discover it after they have already committed to a season on the wrong coast.
I keep a spreadsheet. Sad, I know, but after five summers of moving a 12-metre sloop between the Atlantic, the Channel and the Med I have a fair picture of what a night actually costs, what the headline price hides, and where the marketing photos lie. Here is the honest version for 2026.
The single number that matters: length, not luxury
French marinas price by length overall, full stop. Not by tonnage, not by how shiny the boat is. Your LOA decides your band, and the bands jump in roughly one-metre steps. A 9.95-metre boat and an 11.5-metre boat are in different worlds, and crossing a band threshold by 20 centimetres of bathing platform can cost you a fiver a night every night of the season.
So the first cost-control move is knowing your true LOA, bowsprit and davits included, because that is what gets measured at the quay.
Atlantic and Channel: the affordable coast
This is where your money goes furthest, and it is not close.
La Rochelle is my reference point because the tariff is published and clear. An 11 to 12 metre monohull pays between 41.70 and 52.40 euros a night in high season (1 May to 30 September), and roughly half that, 20.85 to 26.20 euros, in low season when the 50 percent discount kicks in. Water, electricity (1.3 kW), showers and bin access are included. They even throw in a third night free on the daily rate. For a major port on a popular coast, that is fair.
Smaller Atlantic and Channel ports sit in a similar band. Expect 25 to 45 euros a night for a 12-metre boat in season across most of Brittany, Normandy and the Charente, dropping sharply once the schools go back. The pattern is consistent: high season runs May to September, and almost everyone halves the rate outside it.
There is real value in the shoulder months here. I have paid under 25 euros a night in late September in places that were charging 45 in August, for warmer water than people expect and a quarter of the boats. If your calendar is flexible, the Atlantic in September is the best berth value in France.
The Mediterranean: where the bill changes character
Now the other planet.
On the Med a 10 to 12 metre boat typically pays 50 to 150 euros a night in high season, and 30 to 100 off season, and the spread inside that range is brutal. A municipal port in the Languedoc might charge you 40 euros. Saint-Tropez, Cannes Vieux Port, Antibes Vauban in August can ask 100 to 200-plus for the same length, and the fashionable ports near Saint-Tropez are notorious for sitting at the top of that band.
I have written a fuller breakdown of the Riviera specifically in Cote d'Azur marina fees, because the Riviera deserves its own warning label. The short version: you are not paying for a better night's sleep. You are paying for the postcode and the superyacht next door.
A second Med trap: electricity and water are more often metered or charged extra than they are on the Atlantic. Read the tariff sheet. A "60 euro" berth can become 75 by the time you have plugged in and filled the tank.
And in peak August the problem is not the price, it is availability. Getting a berth at all on the Riviera in the second week of August is its own sport, which I covered in finding a French Riviera berth in August. Turning up on spec and hoping is how you end up anchored in a rolly bay paying nothing and sleeping worse.
A rough 2026 ready reckoner for a 12-metre boat
Treat these as orientation, not gospel, because every port sets its own grid and revises it each January.
- Atlantic coast, high season: 35 to 50 euros a night, water and power usually included.
- Channel and Normandy, high season: 30 to 45 euros, included.
- Languedoc and quieter Med, high season: 40 to 80 euros, power sometimes extra.
- Cote d'Azur prime ports, August: 100 to 200-plus euros, extras likely.
- Anywhere, low season (October to April): commonly half the high-season figure.
What the nightly price does and does not buy
Almost always included: the berth, a gate code, access to showers and toilets, bin and recycling, and on the Atlantic and Channel, water and a domestic electricity supply.
Often extra: a shower token in older ports, metered electricity if you run a heater or aircon, laundry, fuel (a separate operation entirely, see where to bunker fuel in France), and any haul-out or pump-out.
Never included and worth budgeting for: the restaurant ashore. A berth in a pretty harbour is an invitation to spend three times the berth fee on dinner. The Riviera ports know exactly what they are doing when they put the moorings next to the terraces.
The honest conclusion nobody likes
Here is my contrarian line, and I will defend it: on the Cote d'Azur in August you are paying for the view from the quay, not for the night afloat. The water is no clearer in a 180-euro berth than in a 40-euro one forty miles west, and you sleep worse because the wash from day-boats never stops. I now treat the famous Riviera ports as a deliberate splurge, one or two nights a season, and spend the rest of my budget on the Languedoc, the Atlantic islands and anchorages.
If your goal is to maximise nights afloat in France on a fixed budget, base yourself on the Atlantic or the western Med, cruise the shoulder season, and keep the glamour ports for the days you actually want the photograph. The spreadsheet says so, and so do my five summers of paying both bills.
