The first time I sailed along the invasion coast I had read the books and walked the cemeteries on a previous trip by car. None of it prepared me for the simple shock of seeing the Mulberry caissons of Arromanches loom up out of a grey morning, exactly where the armada had put them, still sitting in the sea eighty years on. To approach this coast the way the assault fleet did, from seaward, is the one perspective most visitors never get. It changes how you understand the whole thing.
What follows is an account of cruising the landing beaches, not a history lesson. The history is everywhere here and it does not need me to retell it. But the geography only makes sense from the water, and that is the bit a boat gives you.
A coastline built for an invasion, and against one
Stretch a chart of the Calvados coast in front of you and the logic of 6 June 1944 reads straight off it. The five beaches, Utah and Omaha to the west, Gold, Juno and Sword to the east, occupy a run of low, open sand with few natural harbours. That was the whole problem the planners faced: nowhere to land supplies. Their answer was to bring two harbours with them.
Sailing it today, you feel the exposure the soldiers felt. This is a lee shore in any northerly, with a big tidal range and offlying banks, and the same lack of shelter that forced the Mulberry solution makes it a coast you treat with respect. Get the weather wrong and there is nowhere quick to hide, which is why I plan this stretch around a settled forecast and a known bolt-hole.
Arromanches and the Mulberry remains
The centrepiece is the artificial harbour at Arromanches, code-named Mulberry B, the British one. The scale of it still stops me. The first concrete Phoenix caisson was sunk at dawn on 8 June 1944, and by 15 June a further 115 had been put down to form a breakwater arc almost five miles long, running from Tracy-sur-Mer in the west to Asnelles in the east. The largest Phoenix units measured 60 metres long and 17 metres wide and stood as tall as a five-storey building, with empty weights ranging from 1,600 up to 6,000 tonnes.
Through that summer the harbour landed something like 500,000 vehicles and four million tons of stores. Today around 96 caissons remain on the seabed off Arromanches, of which only a handful are still well preserved, the rest slumped and broken by eight decades of weather. At low water on a big tide they stand clear of the sea and you can see the whole arc; near high water only the tops show.
Do not sail in among them. This is a designated wreck site and the remains are unlit, sharp-edged and unpredictable underfoot of your keel. I stand off, slow down, and look. Anchoring close inshore here is only for settled offshore winds and a falling tide where you know your depths cold; in anything else it is an open roadstead and a poor place to be.
The five beaches, west to east
Run the coast and each beach has its own character from seaward.
Utah, the westernmost, sits behind drying sands and the offlying dangers towards the Baie du Grand Vey. The assault waves here were carried south of their planned landing by the tidal stream, a detail that makes complete sense once you have felt the set running along this shore yourself.
Omaha is the long, gently curving bay with the bluffs behind, and it is the one that hits hardest. The US 1st and 29th Divisions met the heaviest defences here and the casualties in the first hours were appalling. Sailing past the quiet beach below the American cemetery at Colleville, with the rows of white crosses just visible on the headland, is not something you forget.
Gold, Juno and Sword run east towards the mouth of the Orne. Arromanches sits at the western end of Gold. Past Juno and Sword you reach Ouistreham, the lock entrance to the Caen canal and the modern gateway for boats heading down towards the city.
Marinas that put you among it
You do not have to anchor off to cruise this coast. Several harbours sit right in the thick of it.
- Port-en-Bessin lies almost exactly between Omaha and Gold, a working fishing port with gated wet basins. It calls itself the heart of the landing beaches, has around 69 berths with a handful kept for visitors, works VHF channel 18, and the entrance is tide-gated, with access roughly two hours either side of high water. Bayeux and its tapestry are a short hop inland.
- Ouistreham, behind its lock at the eastern end, is the all-tide option and the route to Caen for those continuing on.
- Saint-Vaast-la-Hougue, further west towards the Cotentin, is a fine harbour in its own right and ties in neatly if you are approaching the beaches from Cherbourg. Our notes on Saint-Vaast-la-Hougue and the lock arrival cover getting in there.
If you are arriving from England to start this cruise, Cherbourg as a landfall from England is the natural jumping-off point, and from there it is a comfortable day or two east to reach Arromanches.
The submarine pens are part of the same story
It is worth holding the whole picture in your head. The same war that built the Mulberry harbours built the concrete monsters further west along the coast, the U-boat pens at Lorient and Saint-Nazaire that the Allies were trying to neutralise. If your cruise runs on into Brittany, the submarine pens at Lorient and Saint-Nazaire are the other half of the maritime war on this coast, German engineering at the same brutal scale as the Allied harbours at Arromanches. Sailing past both in one season is a strange education in what the Atlantic war actually looked like from sea level.
What the wrecks below you mean
The seabed off these beaches is a war grave and an archaeological site rolled into one. Beyond the Mulberry caissons lie scuttled blockships, sunk landing craft, the Bombardon floating breakwaters and the debris of an invasion fleet. The artificial harbour off Arromanches was formed not only by the Phoenix caissons but by 18 deliberately sunk blockships and a line of 24 floating Bombardons, much of which still litters the bottom. French law protects all of it, and the whole zone is mapped as maritime heritage. For the cruiser this means two things: do not anchor where you might foul something on the bottom, and treat any wreck buoyage you see as a real obstruction, not decoration.
Planning the passage
Tide rules everything on this coast. The range is large, the gated harbours only open around high water, and the streams set hard along the beaches. I build the day around the tidal gate of whichever marina I am aiming for, then work backwards to a departure time, rather than the other way round. The North Brittany and Channel cruising guide thinking carries over here: pick your weather window, leave time in hand, and never arrive committed to a fixed date when the harbour you want only lets you in for four hours a day.
Time it for a falling spring tide and a calm morning, and you can stand off Arromanches with the whole Mulberry arc exposed, engine ticking over, and take the measure of what was built here in a week of June 1944. Sail it in a fresh onshore breeze and you will instead learn, in your stomach, exactly why they had to bring their own harbours. Either way the coast tells you something the cemeteries cannot.
