Two weeks is the smallest amount of time in which the Solent to South Brittany trip stops feeling like a delivery and starts feeling like a cruise. I have done it in ten days and arrived exhausted, having banked nothing but the marina receipts. I have done it across a fortnight and remembered every harbour. The difference is not speed. It is leaving enough slack in the plan that a day of fog or a foul forecast does not blow the whole thing apart.
What follows is the version that works for a couple or a small crew on a 32 to 40 foot yacht making 5 to 6 knots. Adjust the rest days up if you have more time, never the passages.
The shape of the trip
The headline numbers tell you where the effort goes. The open-water crossing is the big one, and the tidal corners in Brittany are the technical ones. Dartmouth to Camaret is about 144 nautical miles direct, which most people break by stopping at L'Aberwrac'h on the north Finistere coast. From there you are coast-hopping south, and the daily legs shrink to comfortable 25 to 40 mile days.
So the fortnight splits into three phases: get to the bottom of the English Channel, jump across and through the tidal gates, then cruise the south Brittany coast at walking pace. The first phase is logistics, the second is seamanship, the third is the holiday.
Days one to three: working down the Channel
If you are starting from a Solent base, the first job is to get west to a jumping-off port. Many crews stage through Salcombe or Dartmouth, picking up a fair tide down the coast. Use this phase to shake the boat down. You want to find the leaks, the chafe points and the seasick crew member before you commit to the long leg, not 60 miles offshore.
I treat the Channel crossing as the first serious decision of the trip. The picking a Channel crossing weather window guide covers what I look for, but the principle is blunt: you wait for the window rather than the window waiting for you. A fortnight has room for two or three weather days. Spend them at the start, before the crossing, not at the end when you are trying to get home.
Days four to five: the crossing and L'Aberwrac'h
The crossing to L'Aberwrac'h is an overnight for most boats. You leave the English coast in the evening, cross the shipping lanes off Ushant at a sensible angle, and aim to close the French coast in daylight because the approach is rock-strewn and the buoyage rewards good eyes. L'Aberwrac'h is the classic first French port on this side because the entrance is navigable in most conditions and there is a visitor pontoon close to the village. I always arrive with relief and a plan to sleep.
This is also where the tides change character. If you have only ever sailed the Med you will find Brittany's range a shock, and the Brittany tides for Mediterranean sailors primer is worth reading before you arrive, because from here south every passage is a tidal calculation.
Days six to seven: the gates, Chenal du Four and Raz de Sein
The two pieces of genuine pilotage on this trip are the Chenal du Four and the Raz de Sein, the channels that take you round the north-west corner of France and down towards Biscay. Both are tidal gates. You go through with the stream under you, at the right hour, and they are straightforward. Get the timing wrong and they are not. The Chenal du Four and Raz de Sein passage guide breaks down the slack-water windows, which usually means leaving L'Aberwrac'h on the morning ebb and timing your arrival at the Raz for the turn.
Camaret, on the Crozon peninsula, is the natural stop between the two gates. It is a working harbour with a deep-water marina, and after the gates you will want a night alongside and a plate of something with a glass of muscadet. From Camaret you are committed to the south coast.
Days eight to thirteen: South Brittany at last
Now the trip earns its name. South Brittany is one of the great cruising grounds of Europe, and the daily legs are short enough that you can sail in the morning and explore in the afternoon. My standing recommendation is to spend these days working between the islands rather than racing along the mainland. The full south Brittany cruising guide covers the ground in detail, but a fortnight gives you time for the highlights.
I would point the bow at the Glenan archipelago first, a cluster of low islands with white sand and clear water that feels nothing like the granite coast you just left. Then Concarneau for the walled town, then on towards the Gulf of Morbihan, an inland sea dotted with islands where the tide rips through the narrow entrance at up to 8 knots on a spring. Time the entrance for slack and the Gulf opens up into one of the most sheltered playgrounds on the coast.
If you have a spare day, Belle-Ile sits offshore and rewards the detour, and the two-week south Brittany itinerary gives a tighter day-by-day plan for cruising this stretch once you are settled in.
Days thirteen to fourteen: where you stop
Here is the truth nobody tells first-timers. A fortnight gets you comfortably to South Brittany, but it does not get you back. If the boat lives in the Solent, you are looking at either leaving it on a berth in Brittany for a few weeks and coming back for the return, or accepting that the return is a separate trip.
La Trinite-sur-Mer makes an excellent place to leave a boat. It is the sailing capital of the bay, with good yards, easy transport links and a marina used to long-stay visitors. The paperwork for leaving a boat in France over winter or for a few weeks is straightforward but worth getting right, and the rules differ for UK-flagged boats since Brexit.
Provisioning, fuel and the practical rhythm
A fortnight is long enough that you cannot simply load the boat once and forget it. I provision in three stages: a big shop in the UK before the crossing, a top-up at L'Aberwrac'h or Camaret once across, and then fresh bread, fish and vegetables daily from the harbours as you go. South Brittany is wonderful for this. Almost every port has a morning market or a quay where the fishing boats land, and eating what came ashore that morning is half the pleasure of the trip.
Fuel needs a little thought because the legs vary so much. The crossing and the tidal gates can burn diesel if the wind dies, so I cross the Channel with a full tank and refill at the first French marina. After that the daily hops are short and you will rarely run the engine hard, but I keep the tank above half because a south Brittany fuel berth keeps its own hours and a Sunday in August is not the day to find it shut. Water is easy on this coast, with most marinas offering it on the pontoon, so the discipline is less about rationing and more about topping up whenever you are alongside.
The rhythm that makes a fortnight work is simple: sail in the morning when the wind is steadier and the tidal gates open, arrive by early afternoon, and spend the rest of the day exploring or resting. Resist the temptation to bank extra miles when the sailing is good, because the days you save get eaten by the days you lose to weather. A fortnight has just enough slack to absorb two or three bad days. Spend that slack wisely and the trip flows. Spend it badly and you are racing the calendar by the second week.
Paperwork you sort before you leave the dock
Since Brexit a UK boat reaching France is arriving from outside the EU, and the admin is more than it used to be. Every crew member needs a passport, and the Schengen 90-in-180-day clock starts ticking the moment you arrive, which matters if you are leaving the boat and flying home and back. Carry the boat registration, the insurance certificate and your radio licence, and keep them together so a customs or Gendarmerie check is a two-minute affair rather than a hunt through lockers. Read the sailing to France after Brexit checklist before you cross, because the one thing you cannot fix mid-passage is a document you left at home.
The realistic verdict
Plan a fortnight as a one-way trip and you will enjoy every mile. Plan it as a return and you will rush. The crossing and the two gates are the only hard parts, and both yield completely to good timing. Get west early, cross on a real weather window, treat the Chenal du Four and the Raz de Sein with respect, and the rest is the kind of sailing you took up the sport for. South Brittany is worth the journey, and a fortnight is exactly enough to arrive there with the boat and the crew still on speaking terms.
