The Leviathan of the Thames: Brunel's Great Eastern Was a Ship 40 Years Ahead of Its Time
Isambard Kingdom Brunel's SS Great Eastern (1858) was a maritime titan. The largest ship for four decades, it could carry 4,000 passengers to Australia without refueling. Its immense size necessitated a revolutionary and difficult sideways launch, marking it as a marvel of its era.
A Vision of Unprecedented Scale
In the mid-19th century, the brilliant engineer Isambard Kingdom Brunel conceived of a ship so vast it could circumnavigate the globe with a single load of coal. His goal: to create a vessel capable of sailing from Britain to Australia and back without refueling. This would revolutionize long-distance travel and trade. The result was the SS Great Eastern, a behemoth of iron that dwarfed every other ship on the seas. At 692 feet long and weighing nearly 19,000 gross tons, she was five times larger than any ship built before her. She was designed to carry 4,000 passengers in unprecedented luxury, a number that would not be surpassed until the 20th century. Her revolutionary design included a double hull for safety and a unique propulsion system combining two massive paddle wheels, a single screw propeller, and six masts rigged with sails.
The Sideways Launch: A Herculean Struggle
The Great Eastern was so enormous that constructing and launching her presented immense challenges. Built on the banks of the River Thames at Millwall, she was too long for a traditional stern-first launch, as she would have crashed into the opposite bank. The only solution was to launch her sideways—an engineering feat never before attempted on this scale. What was planned as a single-day event on November 3, 1857, turned into a grueling, three-month ordeal. The hydraulic rams meant to push her into the water failed, and the ship, nicknamed the 'Leviathan', became stuck on the slipway. It was a public and financial disaster that took months of additional effort and money to finally get her afloat, an ominous start to her career.
A Cursed Masterpiece?
Despite her technical brilliance, the Great Eastern seemed plagued by misfortune. On her maiden voyage in 1859, a massive steam explosion ripped through her forward deck, killing several crewmen. Commercially, she was a failure. The high operating costs and a series of economic downturns meant the Australian route she was built for was never realized. Instead, she was put on the transatlantic run, where her massive size meant she rarely sailed with more than a fraction of her passenger capacity. The ship developed a reputation for being unlucky, a notion fueled by a persistent urban legend that two workers had been accidentally sealed inside her double hull during construction. The writer Jules Verne, who sailed on the ship in 1867, captured the surreal experience of being aboard such a colossal vessel:
On board was a whole population, a world in miniature. The rolling of the ship was scarcely perceptible; one might have believed oneself on terra firma... The passengers, sheltered under a tent, gazed at the calm sea, where the great paddles of the steamer struck the water with mathematical precision.
An Unlikely Second Act: Connecting the World
While a failure as a passenger liner, the Great Eastern’s immense size gave her a second, more glorious purpose. In the 1860s, attempts to lay the first permanent transatlantic telegraph cable had failed because no ship was large enough to carry the thousands of tons of coiled cable required for the journey. The Great Eastern was the only vessel in the world that could do it. In 1866, after a previous failed attempt, she successfully laid the cable connecting Europe and North America, a monumental achievement that transformed global communication forever. For nearly a decade, she served as a premier cable-laying ship, connecting distant parts of the world, including a line from Bombay to Aden.
Legacy of a Giant
The Great Eastern's story is a paradox. She was an engineering marvel that was decades ahead of its time, yet a commercial disaster that bankrupted several owners. For 40 years, she remained the largest ship in the world, a testament to Brunel's audacious vision. Though she ended her days unceremoniously as a floating music hall and billboard before being scrapped, her true legacy was not in carrying passengers, but in a task her creator never envisioned: uniting the continents with the telegraph cable, and proving that sometimes, even a spectacular failure can change the world.
