Leaving the boat in France for the winter and flying home is one of the great pleasures of cruising as a foreigner. You skip the brutal Biscay or Channel passage in autumn gales, the boat is somewhere warmer and cheaper than a UK yard, and you come back in spring to carry on. I have wintered boats in Brittany and on the Mediterranean side, and the sailing logistics are the easy part. The paperwork is where people trip.
The thing nobody tells you is that when you fly home, you and the boat go their separate ways in the eyes of the French state, and each has its own status to maintain.
The boat keeps a clock even when you are gone
This is the one that costs money. If yours is a non-EU boat, the 18-month temporary admission period keeps running while the boat sits on its winter berth and you are at home in Sydney or Southampton. Leaving it in France does not pause the clock. A non-EU boat can remain in EU waters for up to 18 months under temporary admission without import VAT or duty, and the only way to reset that 18 months is to physically take the boat out of EU waters, in practice for at least 24 hours, before bringing it back.
The trap is obvious once you see it: a boat that has been quietly wintering for two seasons can sail straight through its 18-month window while the owner is abroad and not watching. If your timeline is getting tight, sort the reset cruise before you leave, or read keeping a non-EU boat in France beyond 18 months for the options, because this is the single thing most likely to generate a surprise VAT demand.
For UK owners specifically there is the added wrinkle that temporary admission is built for non-EU residents and UK residents do not straightforwardly qualify, so the VAT status of the boat itself matters even more. Know it on paper before you leave it. The detail is in the VAT status of a boat in EU waters.
Your own days do not matter once you have gone, but they will again
Here is the relief. Once you fly home, you stop using Schengen days. Your 90-in-180 count only runs while you are physically in the zone. So an autumn flight home effectively banks days back into your window.
What matters is timing your return. With the day count now enforced automatically (the EU Entry/Exit System began its phased rollout on 12 October 2025 and is due fully operational by 10 April 2026, recording each non-EU entry and exit digitally), you cannot fudge your spring arrival. Work out, before you book the return flight, how many days you will have available in the rolling 180-day window when you land. The full method is in the Schengen 90/180 day rule for boaters. And from late 2026 you will likely need an ETIAS authorisation, the online pre-travel screen at a 20 euro fee valid for three years, to fly back in once it goes live.
Afloat or ashore: the contract is the document
The actual storage decision drives the paperwork. You either leave the boat afloat in the marina on a winter berth, or you have it lifted out and stored ashore in the yard.
Ashore is more secure and lets you antifoul and survey in spring. It is also a properly priced commitment in France. A whole-year ashore package for a small cruiser (around 8 metres) at the Port Adhoc network in 2026 runs roughly 3,000 to 3,300 euros including VAT with unlimited handling, depending on whether you are in Brittany, the Mediterranean or the Atlantic. Per-metre rates at some Mediterranean yards sit near 14 euros per square metre per month for dry storage, often bundled into a six-month lift-wash-store-relaunch package.
Whatever you choose, get the contract in writing and keep a copy on file at home. It should spell out the dates, what handling is included, whether the yard will accept deliveries or contractors while you are away, and crucially who is allowed to move or launch the boat. I once had a yard that would not let my appointed surveyor near the boat because his name was not on the contract. Add the names of anyone who might need access before you leave.
Insurance does not look after itself
Your policy almost certainly has conditions for laid-up periods and for the boat being unattended over winter. Check three things before you fly: that the policy covers the boat ashore or afloat as appropriate, that it covers the months you will be absent, and whether it requires the boat to be lifted out by a certain date or in a yard of a certain standard. Tell the insurer where the boat is wintering and get their confirmation in writing.
A surprising number of claims are refused on a technicality about an unattended boat in winter, not because the damage was the owner's fault. Get the cover right and keep the certificate with the marina contract.
Tell the marina you are leaving, and who can act for you
A surprising amount of winter grief comes from the marina not knowing the boat is unattended and not knowing who to call. Before you fly, give the capitainerie or yard office your contact details, your expected return date, and the name and number of a trusted local who can act if there is a problem. A burst water pipe, a chafed mooring line in a gale, a neighbour's boat dragging onto yours: these happen in February, and the difference between a small bill and a wrecked boat is often whether someone could get aboard quickly.
Put any authorised person in writing. As I learned the hard way, a yard will not let a contractor or surveyor near your boat in your absence if their name is not on the paperwork, and chasing that authorisation from another continent by email is slow. Spend ten minutes naming everyone who might conceivably need access while you are gone.
It is also worth agreeing, in writing, what the yard is allowed to do without asking you. Can they move the boat if the berth is needed? Will they reconnect shore power after a cut? Will they accept a delivery of parts? A short list of pre-agreed permissions saves a transatlantic phone tag in the depths of winter.
A practical close-down list before the airport
This is what I do on the last day, and I keep a record of it because it helps with any later claim.
- Photograph the boat inside and out, dated, so condition is documented.
- Leave the document folder accessible to a trusted contact or the yard: boat registration, insurance certificate, the temporary-admission evidence, the storage contract.
- Give a local contact or the capitainerie a way to reach you, and authorise in writing anyone who may need to board.
- Note the date the boat went on its winter berth, and calculate where that leaves the 18-month customs clock.
- Confirm fuel and battery arrangements with the yard, and whether shore power stays connected.
The wintering itself is the simple bit. France makes it pleasant and the yards are good. The work is in the half-hour of admin you do before the taxi to the airport: maintaining the boat's customs status, locking down the contract and insurance in writing, and knowing exactly where your own Schengen days will stand when you come back to cast off in spring.
