The navigation season on most of the French canal network is not year-round. The Canal du Midi, for example, is open from the third Saturday in March to roughly the first week of November, and other canals run similar windows with maintenance stoppages, the chomages, bracketing the cold months. So if you are cruising France over more than one summer, sooner or later you have to answer the question every long-distance canal boater faces: where do I leave the boat for the winter, and what does that cost.
We have wintered our boat in France three times now, twice afloat and once ashore, and I have opinions on all of it.
Pick the right town before you pick the marina
The single best decision we made was choosing a hub town with real infrastructure rather than a pretty village with a couple of rings on the quay. Saint-Jean-de-Losne, where the Saone meets a knot of canals, is the classic example and the largest river port in the country for a reason. There are chandlers, mechanics, a crane, a brokerage, and other liveaboards who know where everything is. When your fridge dies in February, you want to be somewhere that can fix it.
The same logic applies to other established wintering centres along the major routes. What you are buying is not just a berth; it is access to the people and the kit that keep an unattended boat alive through a French winter. If your boat is sitting somewhere with all this on the doorstep, the Saone and the Doubs make an obvious spring departure once the season reopens.
When the canals actually shut
The reason wintering is forced on you and not optional is the chomage, the annual maintenance stoppage when VNF drains pounds, replaces lock gates and dredges. The dates move year to year and canal to canal, so check the VNF schedule for your specific route rather than trusting a friend's memory of last season. As a guide, the Canal du Midi typically closes for most of January and February (the 2026 winter works ran from 5 January to the March reopening), and the Canal de Bourgogne reopens in late March, with navigation set to resume on Saturday 28 March 2026. Drought has made this less predictable still: the Canal du Midi spent part of a recent winter closed beyond the usual stoppage because water levels were too low to fill the locks. Build slack into both ends of your season, because a canal that should have reopened can stay shut, and the chomage on one canal can strand you on the wrong side of a junction if you cut it fine.
Afloat or ashore
This is the real fork in the road.
Wintering afloat is cheaper and simpler, and the boat stays a boat: you can live aboard, you can keep systems running, you can step on in March and go. The downside is exposure. French winters inland get genuinely cold, the canals and rivers can freeze, and the Saone and Doubs flood with depressing reliability after a wet spell. A boat left afloat needs someone keeping an eye on the lines as the water rises and falls, the heating ticking over or the system fully drained, and the through-hulls thought about.
Wintering ashore, lifted out and chocked in a yard, costs more once you add the haul-out, the storage, and the relaunch, but it removes the flood and ice worry entirely and it is the moment to do antifouling and any underwater work. We hauled out the winter we needed to deal with a tired sterngland, and doing the jobs on hard standing in the quiet months beat fighting for a yard slot in the spring rush.
As a rough planning frame, afloat winter mooring is usually quoted per metre of boat length, billed monthly or as a single off-season block, and it lands well below the cost of summer nightly rates added together. To put rough numbers on it, a 9-to-12 metre boat at a southern town port such as Carcassonne has been advertised around 160 euros a month plus about 4 euros a day for electricity, and a full season afloat at the popular Saone and Burgundy hubs tends to run into four figures across the winter once you add power. Ashore costs more: budget the haul-out, the chocking and storage by the week or month, and the relaunch in spring, and the lift alone on a 12-metre boat is frequently several hundred euros at each end.
Prices vary a lot by region and yard, so get quotes in writing from two or three places before you commit; the spread is wide. The general shape of annual running costs for a boat based in France puts wintering in context against everything else you will spend.
The frost and flood jobs
Whatever you choose, the winterising routine matters more inland than it does on a tidal coast, because the freeze is sharper and lasts longer.
We drain the fresh-water system or fill it with the correct antifreeze, and we never use the cheap windscreen stuff in anything that touches potable plumbing. The engine raw-water circuit gets drained or protected. Batteries come off and onto a maintenance charger, or off the boat entirely if we are leaving it ashore. Dehumidifier running if there is shore power, hatches cracked for airflow if there is not, and every soft furnishing lifted off the cold surfaces or it grows a beard of mould by April.
If the boat stays afloat on a river that floods, slack lines and good long springs are not optional. We have come back to find the pontoon a foot higher than we left it.
Inland frost is the part British coastal sailors underestimate. Eastern France and the Burgundy plateau regularly drop to minus 8 or minus 10 Celsius on still January nights, and the canals and the upper Saone can hold a skin of ice for days. Ice itself rarely crushes a steel barge, but it grips the hull, so a boat frozen in and then lifted by a flood surge can drag its lines or chafe through them. A trickle of antifreeze in every water trap, the engine raw-water side drained, and the gas turned off at the bottle are the non-negotiables. We also pull anything that holds moisture, the cushions and the bedding, off the boat entirely, because a closed-up hull through a damp French winter grows mould faster than you would believe.
If the route down to the sea is part of your plan once spring comes, remember the mast probably stays down for the whole inland passage; our piece on air draft on the French canals is worth re-reading before you book the re-rig at the far end, because the yard slots fill fast in the spring rush.
The paperwork foreign owners forget
Leaving the boat is not only a physical job; there is an administrative side that catches non-French owners out. Non-EU boats in particular need to think about how a long stop interacts with the temporary admission clock and customs, and the rules are not intuitive. We cover the specifics in the paperwork for leaving your boat in France over winter, and it is worth reading before, not after, you walk away for five months.
Get insurance confirmation in writing that you are covered laid up, afloat or ashore as appropriate, because some policies treat winter lay-up differently and a few want the boat unattended only with conditions met.
What I would tell a first-timer
Book early. The good wintering berths in the popular hub towns fill by late summer, and turning up in October hoping for a spot is how you end up somewhere inconvenient. Choose infrastructure over scenery. Decide afloat versus ashore honestly based on what jobs the boat needs and how cold the location gets. And do the winterising properly the first time, because a split engine block discovered in spring will cost more than every winter berth you will ever pay for.
We come back each March slightly anxious and almost always relieved. A boat looked after through a French winter, in the right town, with the right preparation, waits for you perfectly well. It just will not forgive you for cutting corners in November.
