Today, 3 September, we mark Merchant Navy Day; a day to remember, recognise and give thanks to the men and women of the Merchant Navy, past and present.
For many people, the Merchant Navy may feel like a part of Britain's history. The truth is that merchant seafarers remain an essential part of our lives today. Every day, they work at sea transporting the food, fuel, medicines, raw materials and countless other goods on which our communities and economy depend.
Merchant Navy Day gives us an opportunity to pause and recognise that contribution.
What is Merchant Navy Day?
Merchant Navy Day is held every year on 3 September. It was established in 2000 as a national day of recognition for merchant seafarers and their contribution to Britain.
The date also carries a powerful historical significance. On 3 September 1939, the passenger ship SS Athenia was torpedoed and sunk by a German U-boat, becoming the first British merchant vessel lost during the Second World War.
The day therefore has two important purposes: to remember those who made the ultimate sacrifice and to recognise the vital role merchant seafarers continue to play today.
Remembering those who served
During both World Wars, merchant seafarers faced extraordinary dangers.
While not members of the Armed Forces, they sailed into war zones carrying essential supplies. Their ships transported food, fuel, ammunition, equipment and other necessities that Britain and its allies desperately needed.
More than 20,000 British merchant seafarers lost their lives during the Second World War alone.
They faced U-boats, mines, aircraft, storms and the constant uncertainty of sailing through hostile waters. Many never returned home.
Their contribution was quite literally a lifeline for the nation.
Today, we remember not only those who died but also the families who waited for loved ones to return, and the generations of seafarers who served in the years that followed.
The Merchant Navy today
Merchant Navy Day is not simply about looking back.
The Merchant Navy continues to play a crucial role in modern Britain. Commercial ships connect the UK with markets and communities around the world, transporting the goods that keep businesses operating and households supplied.
The UK Government describes merchant seafarers as playing a vital role in global trade, tourism and national security, keeping supply chains moving and supporting the country's economy.
And behind every ship is a crew of people.
Seafarers can spend weeks or months away from their families, working long hours and living in an environment that can be demanding, unpredictable and sometimes dangerous. Their work can easily go unnoticed by those of us on shore.
Merchant Navy Day is a chance to change that.
Why do we fly the Red Ensign?
One of the most recognisable symbols of Merchant Navy Day is the Red Ensign, sometimes known as the "Red Duster".
It is the official flag of the UK's commercial shipping fleet and its Crown Dependencies and Overseas Territories. On Merchant Navy Day, the flag is flown by councils, organisations, maritime businesses and individuals as a visible mark of respect for merchant seafarers.
The flag represents much more than ships.
It represents the people who sail them; their professionalism, courage, commitment and sacrifice.
When we see the Red Ensign flying today, it is a reminder that there are people working at sea who help keep the country supplied, connected and moving.
A day to remember — and to look forward
Merchant Navy Day is ultimately about past, present and future.
We remember those who served during times of war and never came home.
We recognise the seafarers who are at sea today, often far from their families, continuing a tradition that has been vital to Britain's prosperity for generations.
And we look towards the future of the maritime industry; encouraging new generations to understand the opportunities, responsibilities and importance of careers at sea.
This year, that message is particularly relevant. On Merchant Navy Day 2026, eleven seafarers have been recognised with the Merchant Navy Medal for Meritorious Service, celebrating exceptional service, leadership and dedication within the maritime sector.
Their stories remind us that the Merchant Navy is not simply part of Britain's maritime heritage. It is a living, working community that continues to make a difference every day.
So, why does Merchant Navy Day matter?
It matters because it is easy to take the things we rely on for granted.
We see products arriving in shops. We fill our cars with fuel. We order goods online. We expect supplies to be available when we need them.
But much of what reaches us has travelled across the sea first.
Merchant Navy Day reminds us that behind those journeys are skilled people who have chosen a demanding career at sea, people who have served their country in war and continue to serve the nation in peacetime.
It reminds us that remembrance is not only about looking back. It is also about recognising people today and ensuring their contribution is not forgotten tomorrow.
Remember. Recognise. Respect.
So, today, take a moment to look for the Red Ensign.
If you see one flying from a town hall, port, vessel, workplace or landmark, remember what it represents.
Remember the thousands who lost their lives.
Recognise the seafarers who continue to work at sea today.
And respect the families, communities and maritime organisations that support them.
On Merchant Navy Day, we remember those who kept Britain afloat — and we thank those who continue to do so.
We remember. We recognise. We salute the Merchant Navy.
I have included a photo of my Grandad recovering from shrapnel wounds in 1915, when his ship (HMS Pegasus) was sunk by the Germans. He was honourably discharged and went on to serve in the Merchant Navy in the convoys in both wars.
My father is also pictured above, he serve in the Atlantic convoys in the Merchant Navy from 1939.
