The first time the Gendarmerie Maritime came alongside, off Belle-Ile on a flat August morning, my heart did a small flip. Two officers in a grey RIB, life jackets, sidearms, very calm. They asked permission to board, which they do not strictly need but always seem to ask, and then they went through my folder of papers in about four minutes. It was less stressful than a roadside police check in the UK. But it only went smoothly because I had the right documents, in the right form, where I could reach them.
That last part is what trips people up. Not the existence of the papers, but their form and their location.
Originals, not copies. This is the rule that bites.
French law works on a principle that surprises a lot of foreign skippers: a requirement to carry a document means the original. A photocopy, a scan on your phone, a laminated reproduction, none of those satisfy the requirement. I have seen a British crew waved off with a warning because they had photographed their registration and left the original at home "to keep it safe." Keep it safe on the boat, in a dry bag, where you can produce it.
This applies across the board: registration, insurance, radio licence. Carry the genuine articles.
The core set the Gendarmerie wants to see
For a visiting foreign-flagged pleasure boat, the documents that matter are short and predictable.
- The boat's registration document. For a UK boat that is your Part 1 certificate or your Small Ships Register (SSR) certificate. Other flag states have their equivalent. This proves the boat is what you say and flagged where you say.
- Proof of insurance. Third-party liability cover at minimum, and the certificate needs to be current and cover French and EU waters. Carry the actual certificate, in date.
- Your ship's radio licence, if you have any radio equipment fitted (VHF, DSC, EPIRB). For a UK boat this is the Ship Radio Licence from Ofcom.
- Proof of VAT status where it applies. Since Brexit this matters more for UK boats; the background is in bringing a uk flagged boat to France after Brexit and in our piece on VAT status of a boat in EU waters. Carry whatever VAT evidence you have, even if you think you will never be asked.
That is the spine of it. Everything else is supporting cast.
Crew, passports and the post-Brexit border
Since 2021, arriving in France from the UK is crossing an external Schengen border, so passports are part of the document set now, not an afterthought. Every crew member needs a valid passport, and the 90-in-180-day Schengen limit applies to each non-EU person aboard. If you are running a mixed crew, some EU nationals, some not, their requirements differ. The detail sits in the Schengen 90/180 day rule for boaters.
A crew list is a sensible thing to have ready in writing: names, dates of birth, nationalities, passport numbers. It is not always demanded, but producing one instantly makes a boarding faster and friendlier.
What about competence certificates and safety gear?
Two common worries, both usually overblown.
Competence: a visiting foreign-flagged skipper is judged by their flag state's requirements. For a UK boat under 24 metres in coastal waters the UK requires no licence, so the Gendarmerie will not demand one. If you hold an ICC or RYA certificate, carry it, because it does no harm and occasionally smooths things, but it is not a legal must for the visitor. We go into this fully in do you need a licence to sail in French coastal waters and in ICC vs RYA certificates and what France recognises.
Safety equipment: France has a detailed national standard, Division 240, covering flares, lifejackets, fire gear and so on. It applies to French-flagged boats. As a visitor you comply with your own flag state's rules. So an RYA-equipped UK cruiser does not need to rebuild her safety locker to French spec. That said, sensible kit is sensible kit, and a boarding officer who sees current flares and serviced lifejackets forms a good first impression.
Who actually checks, and why there are several of them
It helps to know that "the authorities" on the French coast are not one body. You may meet several, and they have different interests.
The Gendarmerie Maritime is the one most cruisers encounter: a military police force under naval command, around 1,150 personnel operating roughly thirty patrol craft along the coast. They handle general law enforcement at sea, including pleasure-craft checks. The Douanes (customs) have their own fast launches and care about VAT status, dutiable goods, fuel and what you are carrying. The Affaires Maritimes deal with registration and safety matters. In a marina, the capitainerie (harbour office) is your everyday point of contact and will sometimes ask to see paperwork at check-in.
For you the practical upshot is the same whoever turns up: the document folder satisfies all of them. Registration interests the Gendarmerie and Affaires Maritimes; insurance interests everyone; VAT proof interests the Douanes; passports interest immigration. One tidy folder covers the lot.
What a boarding is actually like
In my experience, twice boarded and a handful of times hailed, the Gendarmerie Maritime are professional and unhurried. They will usually ask where you have come from and where you are bound, glance at the boat's condition, and check your folder. They are looking for the obvious: a boat that is registered, insured, crewed by people with valid papers, and not carrying anything it should not. A clean, well-found cruising boat with its documents in order is the least interesting thing on the water to them.
What slows a boarding down is fumbling. Papers scattered across three lockers, an insurance certificate that expired last month, a registration left at home. Get those wrong and a four-minute formality becomes a long conversation.
A couple of habits that have served me well:
- One dry bag, one folder, one job. Everything the authorities might want lives in a single waterproof folder by the chart table. Originals only.
- Check expiry dates before the season. Insurance, radio licence, any certificate with a date on it. An out-of-date document is worse than a missing one.
- Keep a written crew list updated when crew change over. Thirty seconds of admin in port saves a muddle at sea.
- Keep digital backups too, even though they are not legally sufficient. A photo of every document on your phone and in the cloud means that if the originals are lost or stolen mid-cruise you can at least prove what existed while you arrange replacements.
A word on language
You will not be expected to speak fluent French during a boarding, and most Gendarmerie Maritime officers manage enough English to get through a routine check. That said, a few words go a long way. Bonjour at the start, a calm tone, and handing over papers without being asked twice all set the right note. If you are carrying a pet, have the pet documents to hand as well, because an officer who spots a dog will sometimes glance at its paperwork too.
The officers are reading the whole picture: the state of the boat, the demeanour of the crew, whether the documents match the story you tell. None of that requires French. It requires being organised and unflustered, which is much easier when you are not hunting through lockers.
The honest summary
The Gendarmerie Maritime are not out to ruin your holiday. They want to confirm the boat is registered, insured and properly crewed, and that you are who you say you are. The whole thing hinges on one unglamorous discipline: carry the originals, keep them dry, keep them together, and keep them in date.
Do that, fly your courtesy flag (see the French courtesy flag etiquette guide), and a boarding becomes a pleasant exchange with people who, like you, would rather be on the water than doing paperwork.
