The trailer-sailer is the great cheat code for cruising France. While everyone else argues about berth waiting lists and the cost of leaving a boat afloat all year, you tow your boat to whichever coast suits the weather, launch off a slipway for the price of a parking ticket, sail for a fortnight, and tow it home. One season I sailed Brittany in June and the Cote d'Azur in September with the same boat, something no berth-bound owner can do. Here is how to make it work without falling foul of the slipway or the paperwork.
Finding a launch ramp
France is well supplied with public slipways, called a cale de mise a l'eau, and most coastal towns of any size have at least one. They range from a free public concrete ramp with no facilities to a marina slipway with a wash-down area, a rigging pontoon and an attendant who takes a fee. The two things that decide whether a ramp is any use to you are the tide and the gradient.
On the tideless Mediterranean a ramp works at any hour, which is one of the south coast's quiet advantages for a trailer-sailer. On the Atlantic and the Channel the tide rules the ramp. Many slipways only reach water for a band either side of high tide, and a shallow-gradient ramp on a big-range coast can be unusable around low water and treacherous when the bottom is weeded and slick. Check the state of tide before you turn up, because nothing wastes a morning like arriving at a dried-out slip.
I keep notes on specific launch sites by region, including the ones with a decent gradient and a place to rig. The detail for the busy Charente coast, for example, sits in the La Rochelle visitor guide, and the same tide-and-gradient logic applies wherever you launch.
Slipway etiquette and the fees
French slipways run on the same unwritten code as anywhere, and breaking it is the fastest way to annoy the locals.
- Rig in the car park, not on the ramp. Get the boat ready, mast up, sails bent on, bungs in, before you back down. The ramp is for launching, not for faffing.
- Be quick on the slip. Launch, pull the trailer clear, and park it. Recover the same way: stage the boat, back the trailer, winch on, drive clear, then sort yourself out up top.
- Check the bungs. The number of trailer-sailers that launch with the drain plug out is a standing joke for a reason. Do not be the joke.
- Pay the fee where there is one. Marina slipways and some town ramps charge a launch fee, often a few euros to a low-tens-of-euros figure depending on the port and whether you park the trailer there. Free public ramps exist but usually have no facilities.
Parking the car and trailer is the other practical headache. Coastal car parks in season are tight and some ban trailers, so scout the parking before you commit to a ramp, especially in August.
The licence and registration question
This is where visitors get nervous, and the answer depends on what you sail. For a boat under sail, France does not require a licence to skipper it in coastal waters, so a small sailing trailer-sailer can be launched and sailed by a visitor without a French permit. The moment you fit an engine above a modest power threshold, the picture changes, because driving a powered boat at sea in France generally requires a licence once the motor exceeds 4.5 kW (about 6 hp). A small auxiliary outboard below that threshold keeps you in the clear; a bigger motor does not. The visitor's view of which certificates France recognises, and where the ICC fits in, is set out in the bareboat charter France licence guide, and the licensing logic is the same whether you charter or tow your own.
Registration and ship's papers matter too. Bring your boat's registration document, your insurance, and your identification, because the Gendarmerie Maritime do board pleasure craft and ask for them. Carrying the right paperwork for a foreign-flagged boat is part of the wider arrivals admin, and the sailing to France after Brexit checklist covers what a visiting boat should have aboard. A trailer-sailer is still a boat in the eyes of the authorities, even if it lives on a driveway at home for ten months of the year.
Safety kit you must carry
France sets out minimum safety equipment by how far offshore you go, under the rules sailors know as Division 240. The kit list scales with distance from a safe haven: a basic set for staying within a couple of miles, more for the coastal band, and a full offshore inventory beyond. For a trailer-sailer pottering close inshore the basic and coastal lists are what matter, but you must actually carry the required lifejackets, signalling and equipment for the zone you sail in, because it is a legal requirement and it is checked. Do not assume your home-country kit ticks every French box; read the list for the band you will sail and fill the gaps before you launch.
Where the trailer-sailer wins
The whole point of the trailable boat is freedom from the berth. You sidestep the marina waiting lists, the annual berth fee, and the cost of leaving a boat afloat over winter, all of which run into serious money on the French coast. A peak-season marina night for a small cruiser runs into the mid-tens of euros, and the going rates are tracked in the French marina cost per night breakdown, but the trailer-sailer dodges most of that by launching for a daily fee and towing home at the end of the trip.
You also pick your weather. A foul forecast in Brittany is no longer a ruined holiday; you hitch up and drive south to the Med, or inland to a lake, and sail where the sun is. No berth-bound boat can do that. Over a season you can sample three completely different French cruising grounds with one boat and one trailer.
Towing through France: the road rules
Before you ever reach a slipway you have to get the rig there, and the towing rules catch out visitors. France sets a general open-road speed limit of 80 km/h on most single-carriageway roads outside towns and 130 km/h on motorways, but a car towing a trailer is held to lower limits, and a heavy outfit over a combined weight threshold is restricted further still on motorways. Keep to the posted limits for vehicles with a trailer, not the car limits, because the gendarmerie enforce it and the fines are immediate.
Your trailer and its lighting board must be road-legal and properly secured, the number plate on the trailer must match your towing vehicle as required, and a wide or long load needs the correct marking. Check that your insurance covers the boat on the trailer in transit as well as afloat, because the two are not always the same policy. Motorway tolls in France are charged by vehicle class, and a car-plus-trailer outfit usually moves up a class, so budget more for the peage than you would for the car alone on a long tow south.
The reward for all this is real. The drive from the Channel to the Mediterranean is long but the autoroute network is fast, and a trailer-sailer can be sailing a completely different sea two days after deciding the weather has turned. No boat that lives in a berth can match that mobility.
The numbers worth knowing
- France requires no licence to sail a boat under sail in coastal waters, but a powered boat needs one once the motor exceeds 4.5 kW (about 6 hp).
- Launch fees range from free public ramps to a few euros or low tens of euros at marina slipways.
- Safety kit is set by distance from a safe haven under Division 240, so carry the list for your zone.
- Tidal ramps on the Atlantic and Channel often only reach water for a band either side of high tide.
- A peak-season marina night for a small cruiser runs into the mid-tens of euros, which the trailer-sailer largely avoids.
Hitch up and go
The trailer-sailer rewards the planner. Scout the ramp and its tide, rig in the car park, mind the slipway code, carry the right papers and safety kit, and check whether your engine puts you over the licence threshold. Do that and you have the most flexible boat in France: no berth, no waiting list, no winter storage bill, and the whole coastline to choose from each time you load the car. The first time you launch off a free public slip into Atlantic sunshine while the marina crowd are still on the waiting list, the appeal of towing your own boat becomes very obvious.
