The first time I called a French harbour office on VHF, I read out my boat name, my length, my draught and my home port in one breathless burst. The reply was a single word: "Attendez." Wait. I sat there for four minutes off the breakwater at Saint-Vaast wondering if I had done something wrong. I hadn't. The capitaine was just busy with another boat, and the French system assumes you can read a marina without being walked through it.
That is the thing nobody tells you when you cross from the UK or the Netherlands. A French port de plaisance is not the same animal as a British marina with a single pontoon office and a card machine. The logic is different, the staffing is different, and once you understand it you stop feeling like a gatecrasher.
The capitainerie is the brain of the port
Every French marina of any size has a capitainerie, the harbour office. It is staffed by the capitaine de port and a team, and it does everything: berth allocation, fuel, weather, lost windlass handles, the lot. You will see the word on a building near the fuel quay or the main pontoon, often with a green-over-white flag or a prominent sign.
The capitainerie keeps office hours, and this catches visitors out. At Benodet in south Brittany the office and VHF watch run 08:30 to 12:00 and 14:00 to 20:00 in July and August, and shorter hours off season (roughly 09:00 to 12:00 and 14:00 to 17:00). That midday closure is real. Arrive at 13:00 in September and you may find a locked door and nobody answering the radio until 14:00. It is not rudeness, it is lunch, and the French take it seriously.
So the rule I follow: arrive before noon or after 14:00 if you can. If you cannot, tie up anyway and sort the paperwork later. No French capitaine has ever turned me away for arriving during the lunch break.
VHF 9, and what to actually say
Most French marinas monitor VHF channel 9. A few use 12 or 16 to make first contact, but 9 is the working default along the whole coast. Call the marina by name three times, then your boat name, then ask if they read you. Keep it short.
What they want, in order: your boat name, your length overall, and your draught. That is usually it for the first call. They will either give you a berth number or tell you to take any free spot on the visitor pontoon (ponton visiteurs) and come to the office afterwards. If your French is shaky, say "Bonjour, do you speak English?" and almost everyone under sixty will switch. The capitaines on the Channel and Atlantic coasts deal with British boats every single day.
A small thing that saves grief: give your length honestly. French berths are priced and sized by length, and a capitaine putting you in a 12-metre box when you are 14 metres overall (with the bowsprit and davits) is doing you no favour. They will measure on arrival if it matters.
The visitor pontoon and the box berth
Two systems, depending on coast.
On the Atlantic and the Channel, you usually get a finger pontoon or an alongside berth, much like home, because there is tide and the pontoons float. You back or motor in, take your lines ashore, done.
On the Mediterranean it is stern-to or bow-to against a quay, held off by a lazy line rather than your own anchor. That is a different skill, and if you have never done it under the gaze of a packed August quay it is worth reading up first. I wrote a separate piece on how to lay med mooring lazy lines without drama, because the technique is what separates a calm arrival from a shouting match.
Either way, the visitor berths are usually marked. Look for the word "visiteurs" or "passage" on the pontoon, or a berth with a small sign or a different coloured marker. If a berth has a name card or a green "free" tag flipped up, it is generally fair game until told otherwise. When in doubt, take it and check at the office.
Checking in: you go to them
This is the cultural shift. In France you are expected to walk to the capitainerie and present yourself, ideally with the boat's papers. They will want the registration document, sometimes insurance, and your details. They log you, take payment, and hand over the gate code and the sanitaires (showers and toilets) code or a token.
What you pay for the night depends entirely on length and region, and I have broken the numbers down in what a night in a French marina costs. As a rough orientation, an 11 to 12 metre boat in La Rochelle pays between 41 and 53 euros a night in high season and roughly half that from October to April. The Mediterranean in August is a different planet.
Bring a card. Most capitaineries take cards now, though a handful of small Breton and Corsican ports are still cash-only or want exact change for the showers. The fuel quay is sometimes a separate operation with its own card terminal, which I cover in the boat fuel in France guide.
The unwritten etiquette
A few things I learned by getting them slightly wrong.
Rafting is normal and expected when a port is full. If the capitaine asks you to raft against another boat, do it with a smile, run your lines to the pontoon (not just to the inner boat), and cross other boats forward of the mast, never through their cockpit. Ask before stepping aboard. Most French sailors are relaxed about it; a few are not, and you can tell within ten seconds.
Showers usually need a jeton (token) or a code, and they are often timed. The token might cost a euro or two, or be included. Ask at the office rather than discovering the water cuts out mid-rinse.
And the courtesy flag matters more here than people think. A French tricolour at the starboard spreader is basic manners, and a tatty one reads as a shrug. If you are arriving from outside the EU there is also the question of where you must first clear in, which is a whole subject on its own and worth checking against where you must clear customs arriving in France before you pick your landfall port.
What actually goes wrong, and how to avoid it
The mistakes I see from visiting boats are always the same three.
First, arriving at the lunch break, panicking at the silence, and either leaving or grabbing a resident's berth. Don't. Tie up on the visitor pontoon and wait it out.
Second, not having the gate code and getting locked out of your own pontoon at midnight after dinner ashore. Write the code on your hand or your phone the moment they give it to you.
Third, assuming the berth fee includes everything. Water and electricity are usually in the nightly price on the Atlantic and Channel, but on the Med some ports meter electricity separately and charge for water at the quay. Read the tariff sheet pinned in the office.
None of this is hard once you have done it twice. The capitainerie is not a checkpoint, it is a service, and the people behind the desk have seen every flag and every level of French. Call on 9, give your length, find the visitor pontoon, then go and say bonjour. That sequence has never failed me in fifteen seasons of crossing the Channel.
