An extraordinary true story of danger, innovation and deep sea discovery. In 1971 Alec Crawford is determined to make his fortune from ship salvage. Early attempts lead nowhere until he teams up with a new partner, Simon Martin. Diving in Hebridean waters, they explore remains of the Spanish Armada, and the wreck of the SS Politician, the vessel made famous in the Whisky Galore. But money is scarce and irregular, and the work is fraught with danger and disappointment. Until they hear of one of the most incredible wrecks of all time - the White Star Liner Oceanic, which, when built in 1899, was the biggest and most luxurious ship in the world. Widely regarded as an 'undiveable' wreck, lying somewhere off the remote island of Foula, they decide to take the challenge. They face unbelievably dangerous waters and appalling weather conditions, and when a large salvage company takes action against them, they also have a huge legal fight on their hands. But if they succeed, the rewards will be enormous...

From the best-selling author of four classic UK diving books, comes The Darkness Below - a collection of absorbing adventures gained from a lifetime in diving. As one of the UK's leading Technical Divers, Rod takes the reader on a spellbinding and gripping journey, from first beginnings as a novice scuba diver. Told in intimate detail with a beguiling sense of self-deprecating humour, he recounts epic dives on some of the most fabulous shipwrecks around the world. Terrifying first explorations of virgin shipwrecks far offshore, lost in time and enshrouded in darkness in the silent depths, cram the pages. A daring expedition into the heart of the feared Corryvreckan whirlpool, the third largest in the world, an open sea encounter with Orca killer whales and an agonizing attack of the bends keep the reader engrossed. The palpable gloom, despair and human tragedy of the wrecks is never far away - the cold and darkness of the depths almost resonating with the cries of those who have perished. The fear of entrapment inside a wreck is grippingly described and becomes almost claustrophobic to the reader unfamiliar with the perils of wreck penetration, when snagged nets sometimes billow unseen above the unwary diver. However, there are rewards when survivors from wrecks are keen to speak to someone who has seen and touched their ship that had been lost long ago. This is an unmissable book for all divers and anyone interested in maritime history.

From the bestselling author of Breath, a “fascinating, informative, exhilarating” voyage from the ocean’s surface to its darkest trenches (Wall Street Journal).

Fascinated by the sport of freediving—in which competitors descend great depths on a single breath—James Nestor embeds with a gang of oceangoing extreme athletes and renegade researchers. He finds whales that communicate with other whales hundreds of miles away, sharks that swim in unerringly straight lines through pitch-black waters, and other strange phenomena. Most illuminating of all, he learns that these abilities are reflected in our own remarkable, and often hidden, potential—including echolocation, directional sense, and the profound bodily changes humans undergo when underwater.

Along the way, Nestor unlocks his own freediving skills as he communes with the pioneers who are expanding our definition of what is possible in the natural world, and in ourselves.

How do you invent an Olympic sport? For Katharine Whitney Curtis, it took the right idea, great talent, some good timing, and the determination to make it happen. The originator of synchronized swimming as we know it today, she even wrote the first book on the subject in 1936. But there was much more to her life and career. After the start of World War II, Curtis became a recreational director in the American Red Cross and followed the troops wherever the course of war took them, serving under Generals Patton and Eisenhower, before becoming a director of travel for the U.S. Army in Europe during the Cold War. Unbound by fear or the narrow expectations of society, this was a woman who lived ahead of her time, making things happen along the way. As her first biography, this book generously features Curtis's own words, selected from more than 2,000 pages of letters, and contextualized by her surviving friends and family members.

The recorded history of the diving industry has been fundamentally corrupted over the past 150 years. The result is a complete misunderstanding of how it all began. Who invented the diving helmet? Refer to any encyclopaedia or history book and the answer you will find will almost certainly be wrong. The First Treasure Divers reveals the true and fascinating story. It blows away the myths and deliberate misinformation that have crept into the historical record. Thanks to the painstaking research the author has carried out over the past 25 years, the falsehoods are peeled away to unveil the true, definitive account. It follows the lives of two brothers as they struggle to turn their newly-invented diving helmet to advantage and how they wrestle with apathetic and even hostile authorities for recognition of their invention. It thunders through sunken treasure adventures to the heroism and horrors of the Crimean War. The impact of the invention of the diving helmet is immense. In the 180 years since the Deane brothers carried out the first ever commercial helmet dive off the Isle of Wight on the south coast of England, the diving business has expanded to a global industry with an annual turnover in excess of $3,000,000,000. From another point of view, the life-support technology developed in the diving industry provided the knowledge for keeping the pioneering, high altitude pilots alive, which in turn evolved into the life-support systems of the astronauts who walked on the moon.

'The water slips over me like cool silk. The intimacy of touch uninhibited, rising around my legs, over my waist, up to my collarbone. When I throw back my head and relax, the lake runs into my ears. The sound of it is a muffled roar, the vibration of the body amplified by water, every sound felt as if in slow motion . . .' Summer swimming . . . but Jessica Lee - Canadian, Chinese and British - swims through all four seasons and especially loves the winter. 'I long for the ice. The sharp cut of freezing water on my feet. The immeasurable black of the lake at its coldest. Swimming then means cold, and pain, and elation.' At the age of twenty-eight, Jessica Lee, who grew up in Canada and lived in London, finds herself in Berlin. Alone. Lonely, with lowered spirits thanks to some family history and a broken heart, she is there, ostensibly, to write a thesis. And though that is what she does daily, what increasingly occupies her is swimming. So she makes a decision that she believes will win her back her confidence and independence: she will swim fifty-two of the lakes around Berlin, no matter what the weather or season. She is aware that this particular landscape is not without its own ghosts and history. This is the story of a beautiful obsession: of the thrill of a still, turquoise lake, of cracking the ice before submerging, of floating under blue skies, of tangled weeds and murkiness, of cool, fresh, spring swimming - of facing past fears of near drowning and of breaking free. When she completes her year of swimming Jessica finds she has new strength, and she has also found friends and has gained some understanding of how the landscape both haunts and holds us. This book is for everyone who loves swimming, who wishes they could push themselves beyond caution, who understands the deep pleasure of using their body's strength, who knows what it is to allow oneself to abandon all thought and float home to the surface.

Trudy Ederle loved to swim, and she was determined to be the best. At seventeen Trudy won three medals at the 1924 Olympics in Paris. But what she planned to do next had never been done by a woman: She would swim across the English Channel in fourteen hours and set a world record.

As long as already five thousand years ago, the allure of the sea inspired humans to recreate its essence in miniature, artistic forms, as public baths where ancient rituals would take place. Since then, it has become quite normal to immerse ourselves in cooling waters, in the privacy of our homes and without religious incentives. Swimming pools have rapidly become status symbols and the source for many diverse experiences: leisure-time athletics, relaxation, or the simple pleasure of just being in water. It is no wonder then that filmmakers and photographers constantly return to the swimming pool as a subject and setting. Reflections of water and light are captured in countless, unique ways in the more than two hundred compelling images that comprise this catalogue. Also included of course are the images of those who animate it. With works by: Abbas Attar, Henri Cartier-Bresson, Peter Marlow, Martin Parr, Alec Scoth, Alex Webb, and others.
