The question that arrives in my inbox more than any other is the same one I asked before we left: what does it actually cost to live aboard in France for a year? The brochure answer (less than a house!) is true and useless. So here is the real one, itemised, from four years of doing it, with the numbers that surprised me and the ones that nearly sank the plan. Every figure below is for a ten to twelve metre cruising yacht with two adults, in 2025-2026 euros, and your boat will move these numbers up or down. The structure of the budget, though, holds for almost everyone.
The headline: it is the boat, not the living
Before the line items, the single most important truth. The cost of living aboard is not really the cost of living. Food, fuel and berths are predictable and modest. What dominates the budget, and what catches every newcomer, is the boat itself: maintenance, depreciation, the haul-out, the thing that breaks in October. People budget for the marina and forget the gearbox. Do not be those people.
Berths and moorings
The biggest controllable cost, and the one with the widest range. How you handle it depends entirely on whether you keep moving or settle in for the season.
If you take an annual contract, a year-round berth for a mid-sized boat on the Atlantic or in Brittany commonly runs in the low-to-mid thousands of euros per year, while the Cote d'Azur runs to multiples of that. If you cruise in summer and only buy a winter package, the maths shifts: a forfait hivernage for October to March often lands in the 1,000 to 2,500 euro range on the Atlantic, and you pay nightly visitor rates in summer (typically 30 to 60 euros a night for a boat this size in season, more on the Riviera in August). Choosing the right home port is the lever that moves this line most, which is why I spend so long on it in finding a liveaboard-friendly marina in France.
You can slash this line by anchoring. France has superb free anchorages, and a summer spent mostly on the hook costs almost nothing in berth fees, though it costs more in fuel, water runs and wear on ground tackle. My realistic annual figure for a mix of winter package, some summer visitor nights and a lot of anchoring: 3,000 to 6,000 euros.
Insurance
Non-negotiable and easy to underestimate. For a foreign-flagged cruising yacht in French waters, comprehensive insurance for a boat of this value typically runs somewhere in the 500 to 1,500 euro range a year depending on value, cruising area and your history. Med cover often costs more than Atlantic. The wrinkles of insuring a foreign-flagged boat are in insurance for a foreign-flagged boat cruising France, and you should not let it lapse, because a French marina or a clearance officer can ask to see it.
Fuel, water and gas
For a sailing boat this is small. We motor far less than a motorboat owner, obviously, and a season of coastal cruising and canal-free sailing might burn a few hundred euros of diesel. Run the heater hard all winter and add to that. Cooking gas is trivial, perhaps 100 to 150 euros a year. Water is often included with the berth or costs coins at the pontoon. Call the combined fuel, gas and water line 400 to 900 euros for a sailing liveaboard, dramatically more for a motorboat, whose fuel realities are in motorboat cruising in France: range and fuel.
Food and daily living
The good news. France makes eating well cheap if you shop like a local. Markets, the supermarket, the boulangerie run. Two adults eating mostly aboard with the odd harbour lunch can live comfortably on roughly 400 to 600 euros a month, call it 5,000 to 7,000 euros a year, which is not meaningfully different from living ashore and arguably better fed. Provisioning from French markets is one of the genuine pleasures of the life and I would not trim it.
Connectivity, the modern essential
Twenty years ago this line did not exist. Now it funds the work that funds the life. A French data SIM runs around 20 euros a month, and if you add Starlink for offshore and remote work it climbs to 70 to 100 euros a month combined. Over a year that is 850 to 1,200 euros. If you are working aboard it is not optional, and the trade-offs are in working remotely from a boat in France. If you are retired and happy with mobile-only, knock most of the Starlink cost off.
The boat: maintenance, haul-out and the surprise
Here is where budgets die. Annual maintenance on a cruising yacht of this size realistically runs 5 to 10 percent of the boat's value, and many old hands quote that as the honest long-run figure. For a boat worth 80,000 euros that is 4,000 to 8,000 euros a year, averaged over good years and bad.
Within that, the predictable jobs:
- Antifouling and a haul-out: a lift, jet-wash, a few nights ashore on the hard and a coat of antifoul commonly comes to several hundred euros plus paint, often 600 to 1,200 euros all in for a boat this size, more if you do other work while ashore. The French yard side is in antifouling and survey-based work for a boat based in France.
- Standing rigging, sails, the engine service, the thing that fails. Spread over years, this is the line that makes the 5-to-10-percent rule real.
Skip this at your peril. The boat does not care about your budget.
The paperwork and the hidden lines
A few costs nobody warns you about. If you are non-EU, the customs and residency position can carry real cost: a long-stay visa, or the consequences of getting the boat's 18-month clock wrong, which is set out in leaving your boat in France over winter. Healthcare is another: a liveaboard needs cover, and the options run from the British GHIC to private medical insurance, detailed in healthcare for liveaboards in France. Banking, post and the small frictions of having no fixed address all cost a little, covered in banking and bills afloat in France as a non-resident.
Where you can genuinely save, and where you cannot
After four years I have a clear sense of which levers move the budget and which are fixed. Pull the right ones and you can take thousands off the total without making the life worse.
The big lever is berths. Anchoring instead of paying for marina nights is the single largest saving available, and France makes it easy with a wealth of free anchorages along both coasts. A summer spent mostly on the hook, dropping into a marina only to do laundry, fill water and charge up, can cut your berth line by more than half. The trade-off is wear on ground tackle, more dinghy work and a harder winter, but the money is real.
The second lever is the home port. Basing on the Atlantic or in the western Med rather than the Riviera changes the berth and often the insurance line dramatically for the same boat. People fixate on the glamour ports and then wonder why the budget collapsed. Choosing the right base is the highest-leverage decision you make, which is why it gets its own treatment in finding a liveaboard-friendly marina in France.
What you cannot safely cut is maintenance. Every liveaboard I know who tried to save money by deferring the rigging, the seacocks or the engine service paid for it later at a worse moment, usually at sea or in a panic haul-out. The boat is the one line where skimping costs more than spending. Treat the maintenance budget as fixed and find your savings elsewhere.
Insurance is similarly close to fixed: you can shop it, but you cannot sensibly drop it, and a lapse can cost you a marina contract or a clearance. Connectivity flexes with how you earn: mobile-only if you are retired, the full mobile-plus-Starlink stack if the boat is also your office, as set out in working remotely from a boat in France.
Putting it together
Add the lines for a two-adult sailing liveaboard living a real, balanced year (winter package plus summer cruising, working remotely, eating well, maintaining the boat properly):
- Berths and moorings: 3,000 to 6,000
- Insurance: 500 to 1,500
- Fuel, gas, water: 400 to 900
- Food and living: 5,000 to 7,000
- Connectivity: 850 to 1,200
- Maintenance and haul-out: 4,000 to 8,000
That brings the realistic total to roughly 14,000 to 24,000 euros a year for two people, with the boat and the berth choice driving most of the spread. You can do it for less by anchoring more, working remotely on mobile only and sailing an older, simpler boat. You can spend far more on the Riviera with a big modern yacht. But the shape is consistent, and the lesson is constant: budget hardest for the boat, choose your home port carefully, and the rest of this life is cheaper and richer than the one you left ashore.
