A new alternator does not care that you live on a boat. The courier turns up at a street that does not exist for you, scans "address not found", and your part vanishes back into a depot two departments away. This happens to liveaboards in France constantly, and after three years of fixing it the hard way I have a system that mostly works.
Mail is the unglamorous heart of liveaboard admin. Get it wrong and you miss a tax letter, a renewed insurance certificate, or the spare part that is keeping you in port.
Why a boat breaks the postal system
French logistics assume a domicile. A street, a number, a letterbox someone checks daily. You have a hull that might be in Brittany this week and the Vendee the next. Every workaround below is really a way of borrowing a fixed point on land.
The deeper problem is that the same missing address blocks your bank, your healthcare registration and half the forms a resident has to file. I treat post as one strand of a single knot, and the financial strand is in banking and bills afloat in France for non-residents.
Poste restante: the classic, with a price list
The oldest trick still works. Poste restante lets anyone send mail to a named person care of a specific post office. The sender writes your name, the words Poste Restante, and the commune name and postcode. You collect it in person with ID.
It is not free at the receiving end. La Poste charges per item collected: about 1.69 euros for a letter, 0.83 euros for a newspaper or periodical, and 6.11 euros for a parcel. Items are held for 15 days, then returned to sender, so you cannot let it sit while you cruise off for a fortnight.
Poste restante is fine for the occasional letter. It falls apart for anything time-sensitive or for couriers other than La Poste, who generally will not deliver to it.
The marina as your letterbox
The single best fix is the capitainerie. Many ports will hold mail and parcels for annual berth holders at the office, and a cooperative harbourmaster is worth more than any forwarding service.
Two things to nail down before you rely on it:
- Ask explicitly whether they accept couriers (DPD, Chronopost, UPS) as well as La Poste. Some only take the postman.
- Get the exact delivery format they want: usually your name, the boat name, care of the capitainerie, with the port's full street address and postcode.
This is also the document that anchors everything else. A liveaboard-friendly port that holds your post is usually the same one that will issue an attestation of berth for your bank and prefecture. Choosing that port well is half the battle, and I have set out how in the long-stay berth in France for a foreigner.
Forwarding mail when you move on
If you keep a base address back home or in another French town, La Poste offers forwarding, though it is built for movers rather than nomads. Temporary international redirection runs to about 56 euros for 15 days to a month, around 125 euros for six months, and roughly 202 euros for six months to a year. There is also a hold-mail service, garde du courrier, at about 35 euros for up to two months while you are away.
These services keep post from piling up at an address you have left, but they are slow and they do not solve same-week parcel delivery. For that you need a body on the ground.
Private mailbox and domiciliation services
Companies that provide a domiciliation, a registered French address that receives and scans your post, are the professional answer. They give you a stable street address, hold parcels, and forward or digitise letters on request. Costs vary widely, so compare what is included before signing.
For liveaboards who hold a residence permit this can double as the address bureaucracy keeps demanding. Just check the provider accepts it as a justificatif de domicile, because not all of them satisfy the prefecture or the bank. The address requirement is woven through the whole residency process, which I cover in french residency for liveaboards and the visa maze.
Chandlery and spares: deliver to where the work happens
The parcels that hurt most to lose are boat parts. My rule is to never have them shipped to a generic address.
- For yard jobs, have the part delivered straight to the boatyard with your name and the booking reference. They expect trade deliveries and sign for them daily.
- For self-fit jobs, use the capitainerie or a local chandler who will receive it as click-and-collect.
- For anything urgent, pay for the tracked courier and give a mobile number the driver can actually ring. A French SIM matters here, which is why I keep one even though my phone is foreign.
When a boat lift or haul-out is involved, timing the spares to land while the boat is out of the water saves a second trip. The seasonal logistics of that are in keeping your boat afloat over a French winter, which doubles as a checklist for the lift-out crowd.
Lockers and pickup points
France has a dense network of parcel pickup points, the points relais, in tabacs, supermarkets and lockers. Many online retailers let you ship to one for a small fee or free, and they hold the parcel for several days. For a liveaboard this is gold: you choose a relais near whichever port you are in, collect with the code on your phone, and no driver ever has to find your non-existent address.
The catch is that lockers have size limits, so they suit consumables and small chandlery rather than a folded bimini frame. For the big stuff, fall back on the yard or the capitainerie.
The letters that actually matter
It is easy to obsess over parcels and forget that the dangerous post is the boring envelope. The pieces of mail that can genuinely cost you are official: a prefecture letter asking for documents to renew your carte de sejour, a tax demand with a payment deadline, an insurance renewal you must acknowledge, or a CPAM request for proof before your healthcare cover continues.
Miss one of these because it sat in a post office for 15 days and went back to sender, and the consequences run from a fine to a lapse in your right to stay. This is why I push so hard for a stable, monitored address for official mail, separate from the casual parcel arrangements. A domiciliation that scans and emails your letters means you see the prefecture's deadline the day it arrives, not three weeks later when you next collect.
Tie your official address to the one your bank and prefecture already hold, so nothing falls between systems. The thread connecting all of it runs through banking and bills afloat in France for non-residents, because the same address serves the account, the tax return and the post.
Timing collections around your cruising
The 15-day hold on poste restante and many parcel points is the trap for anyone who actually moves. A part shipped while you are mid-passage to the next port can be returned before you arrive.
My habit now is to never order anything physical until the boat is settled somewhere for at least a week, and to confirm the hold period for that specific relais or office before I click buy. For longer absences, I switch the official mail to the domiciliation, which holds indefinitely, and pause online orders entirely. It sounds obvious written down. It is the exact mistake I made twice before it stuck.
The system I actually run
After enough mistakes, here is the stack I use. A domiciliation address for anything official and persistent, so the bank, the prefecture and the insurer always have one stable line. The capitainerie for parcels while I am in port. A points relais near wherever I happen to be for online orders. And poste restante only as an emergency for a single letter.
It sounds like a lot of moving parts because it is. But mail is the thread that holds a paperless, address-less life together, and the half-day spent setting it up properly saves the lost alternator, the bounced tax letter and the missed insurance renewal. If you are still weighing up whether the whole thing is worth it, the wider reckoning is in living aboard in France as a foreigner.
