The Mariner's Mirror Podcast

In this episode of the Mariner’s Mirror podcast, we explore the extraordinary life of Harold Derber — a British Merchant Navy veteran whose early training as a wireless operator during the Second World War set him on an unexpected and remarkable path. From the dangers of Atlantic convoys to the political turbulence of the Cold War, Derber’s story moves far beyond the bridge of a ship.
Derber would go on to become one of the pioneers of the modern drug trade, developing the concept of the “drug mothership” and operating a ghost fleet that supplied hundreds of tons of marijuana to post-war America. His journey took him from humble beginnings in Manchester to a violent end on the streets of Miami.
To uncover this fascinating story linking maritime history and true crime, Dr Sam Willis spoke with author David Tuch, whose debut book The Wireless Operator investigates Derber’s life in remarkable detail. Tuch also has a personal connection to the story — he is a descendant of the elusive smuggler himself.

This episode continues our mini series on the history of the Clan Line, one of the most prominent and enduring British shipping companies of the late 19th and early 20th centuries. Founded by Charles Cayzer, the Clan Line became synonymous with reliability, global trade expansion and the professionalisation of British merchant shipping. At its peak, it had one of the largest merchant fleets in the world, forming a crucial part of Britain's maritime commercial power. These ships linked Britain to its colonies and trading partners across Africa, India, Australia and the Far East, moving everything from manufactured goods to raw materials.

This is the third in our series on the Clan Line. We've heard previously an overview of the company from Jamie Cayzer-Colvin, a descendant of Charles Cayzer, and now director of Caledonia Investments, which was born from the Cayzer family's shipping business. We've also traveled all over the country to find sailors who served on the Clan Line ships to hear their brilliantly entertaining stories of their time afloat.

This episode looks at the ships. One of the fascinating things about the ships of the Clan Line is that from sail to steam to motor ships, they continually adapted to advances in ship design and propulsion. The business was always an early adopter of efficient cargo handling and modern engineering standards influencing how liner companies manage global routes and logistics. This means that the ships of the Clan Line almost perfectly act as a mirror of merchant ship evolution, a microcosm of the shifting tides in maritime design over more than a century.

This episode takes us from London, where Dr Sam Willis explores some beautiful models of Clan Line ships with Simon Stevens, curator of ship models and small boats at the Royal Museums in Greenwich. Sam then heads to the Clyde estuary, to the shipyards where many of the Clan Line ships were built and speaks with speak with Vince Gillen, Inverclyde historian and writer.

In today’s episode, we leave the dockyards and engine rooms behind to step aboard the ocean liner as it appears not at sea, but on the page. From the gilded salons of Edwardian fiction to the psychological depths of modernist prose, ocean liners have long served as floating stages for human drama, capturing the hopes, tensions, and contradictions of the modern age. We explore how writers such as E.M. Forster, Noël Coward, Virginia Woolf, Katherine Mansfield, and Agatha Christie used these vast ships as microcosms of society—places where class, desire, ambition, and anxiety collided in close quarters. Christie’s fascination with liners, in particular, reveals how perfectly they lent themselves to closed-circle mysteries: isolated worlds where familiar social types gather, secrets simmer, and violence quietly waits beneath the surface. The conversation ranges from glamour and luxury to migration and the uneasy faith in progress that defined the early twentieth century. Ocean liners emerge as symbols of empire and innovation, but also of displacement, vulnerability, and transition—spaces where identities could shift and certainties dissolve. To find out more Dr Sam Willis is joined by the brilliant Professor Faye Hammill, whose work illuminates why these ships so powerfully shaped literary imagination, and why they continue to haunt it today.

The true story of Mary Ann Patten, a nineteen-year-old woman who, in the summer of 1856, took command of a clipper ship and navigated it around Cape Horn. What drives someone to leave behind security, reputation, and the expectations of society to sail into the unknown? In this episode, we explore To The Edge of the World with author Tilar Mazzeo—a gripping true story of adventure, obsession, and the irresistible pull of the sea. We discuss the extraordinary life at the heart of this book: a woman who refused to accept the limits placed on her and instead chose a life defined by risk, freedom, and relentless determination. Through treacherous waters, isolation, and moments of triumph and despair, Mazzeo paints a vivid portrait of what it means to chase a dream when the world insists you shouldn’t. Her journey is as much an inner reckoning as it is a physical voyage to the farthest reaches of the globe. Along the way, we discuss the book’s rich historical context, the emotional costs of ambition, and the complicated line between courage and obsession. This episode asks big questions about independence, belonging, and why the call of adventure can be so powerful that it demands everything in return. Whether you’re drawn to true stories of exploration, fascinated by lives lived outside convention, or simply curious about what lies beyond the horizon, this conversation will take you right to the edge of the world—and what it means to live there.

This episode explores the fascinating history of the Glenlee, a tall ship built in Glasgow 1896 and restored by the Clyde Maritime Trust. Originally a cargo ship, the Glenlee survived fifteen voyages around Cape Horn and later served as a Spanish Navy training vessel during the fascist dictatorial rule of Francisco Franco. After being neglected, she was rescued and restored, showcasing Scotland's maritime heritage. To find out more Dr Sam Willis spoke with Lauren Henning, the Glenlee's learning and museum manager. They discuss the ship's construction, her role in various maritime adventures, links with Spain's fascist history, and her significance in Glasgow's maritime past. The conversation also highlights the ship's educational programs and the efforts to preserve its authenticity. Hosted on Acast. See acast.com/privacy for more information.
