There is a particular pleasure in eating a fish you pulled out of the water an hour before, cooked in a pan the size of a dinner plate, anchored off a Brittany island with nobody else in sight. Cruising the south Brittany coast you do not have to buy all your seafood, you can catch a fair amount of it, and the waters here are generous if you know what you are allowed to take and how to cook it without a proper kitchen.
A word of caution before the recipes. Recreational sea fishing in France is free and needs no licence for line fishing from a boat, but it comes with real rules on minimum sizes and daily limits, and the Affaires Maritimes do check. Take an undersized fish and you are looking at a fine, not a stern word.
Know the sizes before you keep anything
The single most useful thing you can carry is a small ruler or a marked length on your fishing knife, because almost every species has a legal minimum size and putting back the small ones is not optional.
The fish a cruising boat most often catches off Brittany is bass, and bass is tightly managed. The minimum keeping size is 42 centimetres, and in the north-west of France the recreational limit is three bass per angler per day during the open season, which runs from the first of April. In February and March it is catch-and-release only, and landing a bass in that window is forbidden outright. Measure every bass, count your catch, and when in doubt, put it back.
Shellfish you gather on foot or in pots have their own minimums, harmonised across the Atlantic, Channel and North Sea in early 2026:
- Brown crab (tourteau): 15 centimetres across the shell.
- Spider crab (araignee): 12 centimetres.
- Lobster (homard): 8.7 to 9 centimetres carapace depending on region.
These apply to everyone, professional and recreational alike, and they exist for a reason: a spider crab below 12 centimetres has not yet bred. Take only what you will eat that day, and leave the breeding stock in the water.
What is worth fishing for from a cruising boat
You do not need a charter boat full of rods. Most of what I catch comes from a single handline or a light rod trailed behind the boat at a couple of knots, or dropped at anchor over a likely bit of ground.
Mackerel are the cruising family's bread and butter. They run in shoals off Brittany through the summer, they hit a string of feathers the moment you find them, and a dozen come aboard in minutes when you are over a shoal. They are oily, they do not keep, so you eat them the day you catch them, which suits a boat with little refrigeration perfectly. Pollack and bass come to a lure worked near rocks or over reef at the turn of the tide. If you have pots and know the ground, crab and lobster are there, though pots are a commitment and a fouling risk under way.
When the fishing is poor, the market and the criee fill the gap, and Brittany is one of the best places in Europe to buy what you could not catch. Mussels in particular are cheap, around 7.49 to 9.87 euros a kilo, and the French portion is a full kilo per person as a main. Buying versus catching is a sliding scale, and the wider provisioning picture is in the notes on galley meals from a French market haul.
Gear that earns its stowage
You do not need a tackle box that fills a cockpit locker. The kit I actually use on a cruising boat is small. A handline on a wooden frame for trailing or jigging, a string of mackerel feathers, a couple of soft lures and metal jigs for bass and pollack, a landing net, a sharp gutting knife and that marked ruler for checking sizes. The whole lot fits in one bag.
The single most useful technique from a cruising boat is trailing a lure or a string of feathers at slow speed, two to three knots, as you motor between anchorages. You catch supper while you make passage, which costs you nothing in time. The other is jigging at anchor over rough ground at the turn of the tide, when fish move in to feed. Dawn and dusk out-fish the middle of the day by a wide margin, so the watch-keeper on an early start is the one who fills the pan. If you want to push the fishing side further, the broader notes on provisioning a two-week France cruise cover how catching your own fits into the wider food plan.
Cooking the catch aboard
Fresh fish needs almost nothing done to it, which is just as well in a galley the size of a cupboard. The single best thing you can do with a mackerel an hour out of the water is gut it, score the skin, and fry it in a hot pan with a knob of butter for a few minutes a side. No marinade, no sauce, a squeeze of lemon if you have one. A bass the same way, or wrapped in foil with herbs and baked in a covered pan over a low flame.
Mussels and crab are the one-pot meals of the shellfish world. Mussels steam open in three to four minutes in a covered pan with a glass of white wine and a chopped shallot, the classic mariniere, and you mop the juice with bread. Crab you boil in seawater, around eight to ten minutes for a good-sized tourteau, then pick the meat at anchor with a beer and no hurry. The salt water is free and does the seasoning for you, which saves your fresh-water tank, a real consideration when the working figure is only five to six litres per person per day.
Cooking fresh and cooking simple is the whole approach to a boat with little cold storage, and it ties straight into keeping food fresh without much refrigeration. You catch it, you cook it, you eat it, and nothing sits in a warm locker waiting to go off.
A few habits that keep it legal and good
Gut and bleed fish straight away, over the side, because a fish that sits whole in a warm cockpit deteriorates fast and an oily one like mackerel turns within hours. Keep what you catch in a bucket of seawater or a damp cloth in the shade, not in the sun on the side deck.
Carry the rules with you. Sizes and limits change, the 2026 changes to crab sizes being a good example, and the Affaires Maritimes do board recreational boats. A quick check of the current minimum sizes before the season starts costs nothing and saves an awkward conversation.
Foraging the shore at low water
Not all the seafood comes from a hook. South Brittany has some of the biggest tidal ranges in Europe, and a big spring tide uncovers acres of rock and sand where you can gather shellfish on foot, what the French call peche a pied. Cockles and clams in the sand, winkles and limpets on the rocks, mussels on the lower foreshore, and if you know the ground, the occasional spider crab tucked under a ledge. It is a fine way to spend the hour either side of low water with a bucket and a short rake, and the children love it.
The rules apply just the same on foot as afloat. Shellfish have minimum sizes, daily quantities are capped, and crucially the water has to be clean: classified gathering zones are posted locally, and you do not gather near a harbour mouth or a river outflow where the water carries run-off. Check the local notices, because a bucket of cockles from a polluted flat will make the whole crew ill. The cooking is the simplest of all, a quick purge in clean seawater to spit out the sand, then steamed open in a covered pan exactly like mussels.
Cook fresh, eat the same day
The thread running through all of this is that fresh seafood does not keep, and on a boat with little refrigeration that is a feature, not a problem. You catch or gather what you will eat that day, you cook it within hours, and nothing waits in a warm locker. It is the same discipline that governs eating well without a fridge, and it ties straight back to keeping food fresh without much refrigeration, where the wider point is that a boat eats best when it eats what the day provides.
And take only what you will eat. The Brittany coast feeds cruisers well precisely because generations of fishermen, professional and amateur, have mostly respected the sizes and the limits. Catch your supper, leave the rest, and the next boat through gets to do the same.
