CERFA is one of those French words that means nothing until it suddenly means a great deal. It stands for a long-defunct committee, but in practice a CERFA is simply an official numbered French government form. Every administrative act in France has one, and a boat owner crossing the system eventually meets a few. The number matters, because asking for the wrong CERFA gets you a blank look, and the right one gets you served.
Most visiting cruisers will never touch a CERFA at all. You arrive, you cruise, you leave, and your own country's registration papers do the work. But the moment you buy a boat in France, register one, change something, or deal directly with the administration, the forms appear. Here is a field guide to the ones you are most likely to encounter.
First, what changed in 2022
You will find a lot of out-of-date advice online, so start here. On 1 January 2022 France merged two separate procedures, francisation (declaring a boat French) and immatriculation (registration), into a single act. The old paper certificate of francisation and the certificate of registration became one document, the Boat Registration Certificate. Customs (the Douane) stepped back from francisation, and responsibility moved to the maritime affairs administration (the DDTM) for registration and to the DGFIP, the public finances directorate, for collecting the annual tax.
The upshot for forms: a lot of pre-2022 CERFA references you will see quoted are obsolete, and much of what used to be a paper form is now an online procedure on the demarches-plaisance.gouv.fr portal. If a forum post tells you to post a particular old form to your local customs office, check whether that office even handles it any more.
The fiche plaisance: the one most owners meet
For registering a pleasure boat in maritime waters, the central document is the fiche plaisance. This is the form that registers the vessel, assigns it a registration number (a series of digits preceded by the district initials, displayed on the hull once engine power passes the threshold), and produces the navigation title. Registration is mandatory from 2.50 metres of hull length for any motorised or sail vessel, so even a modest tender with an engine can fall in scope.
You can submit the fiche plaisance by post or, increasingly, complete the whole thing online. For a foreign owner this only becomes relevant if you decide to put the boat on the French flag, which is a deliberate choice with tax and obligation attached. Before you do, read French boat registration for foreign owners, because flagging French brings the annual DAFN duty with it and is rarely the right move for a short-term visitor.
Forms around buying and selling
If you buy a boat in France, the change of ownership has to be recorded. There is a declaration of sale and a change-of-owner procedure that the buyer and seller complete, and the registration is updated into the new owner's name. Get this wrong and you can be left holding a boat whose papers still name the previous owner, which causes problems the first time an official asks to see them. The mechanics of the purchase, including which paperwork passes hands, are covered in buying a boat in France as a foreigner.
Selling a foreign-flagged boat while it sits in France is a different animal again, because you may be deleting it from one country's register and the buyer registering it in another, with French customs interested in where the VAT lands. That sequence has its own pitfalls, which is why I treat it separately in selling a foreign-flagged boat in France.
The commercial forms you will probably never need
For completeness, because their numbers float around online and confuse people: the formally numbered CERFA forms in the boating space mostly belong to commercial and fishing vessels, not private pleasure craft. The set includes forms for reserving a vessel name, registering a commercial or fishing boat, recording an ownership change, changing register, issuing a new certificate, and deletion or suspension from the register, each with its own CERFA number in the 158xx range. Unless you are flagging a charter business or a working boat in France, these are not your forms. If someone hands you one for a private cruising yacht, something has been misunderstood.
Customs and arrival paperwork
Arriving from outside the EU brings its own declarations rather than CERFA registration forms. The act of clearing in, declaring crew and goods, and proving the boat's status is administrative but separate from the registration forms above. What you actually have to declare on arrival is set out in arriving from outside the EU and what to declare, and the document a non-EU owner most wants close to hand is not a CERFA at all but the boat's status evidence, covered in proof of VAT paperwork for your boat.
The online portal versus the paper form
Since the 2022 reform, the centre of gravity has shifted online. The demarches-plaisance.gouv.fr portal now handles most pleasure-boat registration and change-of-ownership procedures that used to involve posting a paper fiche plaisance to a customs office. For a foreign owner this is mostly good news, because an online submission routes itself to the right administration without depending on which regional office happens to handle your district.
It is not entirely frictionless. The portal expects a French-style identity and address setup, and a non-resident with a foreign address can hit validation snags, particularly around proving identity and providing a contactable address in France. The workaround most owners use is to lean on the capitainerie of their home port or a local broker, who deal with the portal routinely and can flag a missing field before the submission bounces. Paper submission still exists as a fallback, but it is slower, and a posted form to the wrong office is the classic way to lose a fortnight.
What an official actually wants to see
The forms are only half the story. Whether you are registering, transferring ownership or simply being asked to account for the boat, the supporting documents are what make a CERFA go through:
- Proof of identity for the owner, and proof of ownership of the boat (the bill of sale or deed).
- The builder's plate or CE marking details, which establish the boat's category and conformity.
- Hull length and engine administrative power, the two numbers that set tax bands and several legal thresholds.
- The existing registration document, if the boat is already on a register somewhere.
- Proof of insurance, at minimum third-party liability, which French ports want anyway.
Have those scanned and to hand before you start, and a form that looks intimidating turns into ten minutes of typing. Start a form without them and you will abandon it halfway. The same document set, kept tidy aboard, is what answers a quayside check, which is why I treat the registration paperwork and the proof file as two halves of one habit in proof of VAT paperwork for your boat.
How to deal with a CERFA without losing a morning
A few habits make French forms painless.
- Get the exact current form name or number from the official source (service-public.fr or the relevant ministry portal), not from a forum, because the 2022 reform invalidated a lot of old references.
- Use the online portal where one exists. Postal submission still works but is slower, and a non-resident address can confuse the routing.
- Have your documents scanned and ready: proof of identity, proof of ownership, the builder's plate or CE marking details, and engine power, which determines several thresholds.
- Write your registration district and any reference numbers on a card kept aboard, so you are not hunting them when an official asks.
- If your French is shaky, the capitainerie staff or a local broker will usually point you at the right form. The fee for an hour of a broker's time is cheap against a refused submission.
The forms are not the obstacle. The obstacle is doing the wrong one, or an obsolete one, and waiting weeks to discover it. Confirm which CERFA your situation actually needs before you fill anything in, and the French paper machine turns out to be more orderly than its reputation.
