Most of the dramas I have witnessed at French fuel berths were not caused by wind or tide. They were caused by someone arriving too fast with no plan, usually short-handed, sometimes alone, trying to do six things in the four seconds it takes a boat to slide past a pontoon. Coming alongside a fuel berth single-handed is entirely manageable. It is mostly a matter of slowing everything down, preparing on your terms before you ever turn towards the dock, and accepting that the only thing that needs to happen in those four seconds is for one line to go on one cleat.
I sail alone a good deal along the French coast and I refuel alone far more often than I would like, because the fuel pontoon (the "ponton a carburant") is rarely where you want it and the queue is rarely short. Here is the routine that keeps it boring.
Plan the whole thing before you arrive
The fuel berth is not somewhere to improvise. Before you get close, you should know:
- Which side you are going alongside, and therefore which side to rig fenders and lines.
- Where the pump is on the pontoon, so you stop with your filler cap beside it, not ten metres short.
- Which way the wind and tide are setting, because solo you have no crew to fend off a misjudgement.
Call ahead on VHF if the harbour monitors a working channel, usually 9, and ask whether the berth is free, which side to take and whether it is self-service or attended. Many larger French ports now have card-operated self-service pumps that run outside office hours, which is a gift to the single-hander because there is no one waiting on you. Marine diesel in French pleasure ports ran between roughly 1.77 and 2.10 euros per litre in early 2026, with island and Corsican ports above 2.20, and SP98 petrol for outboards between about 1.88 and 2.16, so know roughly what you will spend and have a card that works at the pump.
If fuel logistics are a recurring headache on your cruise, it is worth reading more broadly about where to boat fuel france where to bunker, because choosing the right port to fill at saves both money and the stress of a tricky berth.
Rig for solo berthing
The single most useful thing I do is rig a midship line. A line led from a strong cleat amidships, outside everything, ready in my hand or under a turn on the winch, lets me step or step-and-pass it onto the pontoon cleat first. Once that one line is on and I have a turn around a winch, the boat is held. Engine astern against a forward midship spring will pull the stern in and pin the boat to the pontoon while I sort everything else at leisure. That is the whole trick.
Fenders go on the right side and at the right height for a pontoon, which is usually lower than a harbour wall. Two bow, two amidships, one aft is plenty for most boats. Bow and stern lines are coiled and ready to deploy after the midship line is made fast, not before.
The approach
Come in slow enough that you could stop the boat by stepping off, then halve it. A fuel berth approach is the textbook slow-speed manoeuvre: just enough way for steerage, the bow angled gently in, then a touch astern to kill the last of the way as the midship section comes level with your chosen cleat.
Read what the boat will do. With wind or tide setting you onto the pontoon, life is easy: let it carry you the last metre and the midship line just stops you sliding along. With wind or tide setting you off, you need a little more angle and a little more decisiveness, because a half-hearted approach leaves you blown off into open water with your line trailing. When it is really blowing across the berth, there is no shame in standing off, waiting for a lull, or asking a neighbour on the pontoon to take a line.
The same calm, prepared, low-speed method is what makes picking up a french visitor mooring buoy manageable on your own, and the muscle memory carries across.
Step off, make fast, then breathe
When the boat is alongside and the midship line is holding her against the engine, stop. Take the engine out of gear, get your bow and stern lines on, then shut the engine down. Only now do you deal with the filler cap. There is no rush. Boats waiting in the queue would rather you took an extra minute and did it cleanly than rushed and fouled the berth.
Watch your fuel filler in the swell if the berth is exposed. On an Atlantic coast pontoon a passing wake can lift the boat just as you are pouring, and diesel over the side is both expensive and an environmental offence that French ports take seriously. Have a rag and an absorbent pad ready under the nozzle.
Practising the spring-line stop
If you only take one technique away from this, make it the standing spring. The idea is simple: with one line led forward from amidships to a pontoon cleat, putting the engine slow astern pulls the stern in towards the pontoon and pins the whole boat alongside, held firmly against both the line and the propeller thrust, without you touching another rope. The boat sits there as if glued, and you can step off, sort the bow and stern lines, and refuel at leisure.
It is worth practising this on an empty pontoon on a quiet afternoon before you need it on a crowded fuel berth in a crosswind. Rig the midship spring, come alongside, get the line on, and feel how the boat behaves as you adjust the throttle astern. Once you trust it, the fuel berth stops being intimidating, because you know that the instant one line is on, the boat is under control regardless of what the wind is doing.
The same principle gets you off again. With the engine ahead against an after spring (a line led aft from amidships), the bow swings out; with it astern against a forward spring, the stern swings out. Choose whichever takes the end of the boat that is upwind or up-tide away from the pontoon, slip the spring, and you are clear. Springs do the work that a crew would otherwise do by hand, which is exactly why they matter so much to the single-hander.
Reading the berth before you commit
Take a slow pass along the fuel pontoon before you turn in, the same way you would size up a strange anchorage. Note where the pump and the hose reach to, which way other boats are lying, whether there is a current setting along the pontoon, and whether the berth is exposed to wakes from the harbour entrance. On a busy summer morning there may be a queue, and the polite thing is to hold off in clear water until the berth ahead of you leaves, rather than hovering on top of the boat that is fuelling. French ports run their fuel berths informally but there is an etiquette to it: take your turn, do not dawdle once you are done, and move off promptly to let the next boat in.
Paying and getting away
At a self-service pump you tap your card, fuel, and you are done. At an attended berth you pay at the kiosk, usually by card though some smaller ports still want cash, so carry both. Take your receipt; if you are a non-EU boat or ever need to demonstrate where you bought duty-paid fuel, the paperwork matters.
Leaving solo is the reverse of arriving and often the easier half. Single up to the midship line and one other, start the engine, then use a spring to swing the bow or stern off as needed before slipping the last line and motoring clear. With the tide running it is usually simplest to let it do the work: slip, let the stream take you off the pontoon, then engage ahead once you are clear.
None of this is hard once you have done it a few times, and the discipline pays off everywhere else. The single-hander who can put a boat gently alongside a fuel berth in a crosswind can put it anywhere, which matters when your passage timing is fixed by a tidal gate and you need fuel before a long leg like the crossing bay of biscay small boat. Slow down, rig the midship line, and let the boat come to the pontoon rather than throwing it there.
