Panama Canal

 The Panama Canal

The Panama Canal is one of the world’s most remarkable engineering feats. Carved through the narrow Isthmus of Panama, the 82-kilometre artificial waterway connects the Atlantic and Pacific Oceans, transforming global trade and travel by providing a shortcut between the two oceans and eliminating thousands of miles from many sea voyages.

Yet the significance of the canal is about far more than the distance saved. At either end, an extraordinary system of locks raises and lowers ships, while beyond them lie the vast waters of Gatún Lake, narrow channels and dense, jungle-clad landscapes filled with wildlife. To travel through the canal is to experience an extraordinary combination of human engineering and tropical wilderness, a place where enormous ships are lifted and lowered through a series of locks while the jungle presses close to the waterway.

Some ships make the full transit, which takes the ship across the entire canal, from the Atlantic to the Pacific or in the opposite direction.

Others undertake a partial transit, entering the canal from the Caribbean side, passing through the Gatún Locks and sailing into the vast expanse of Gatún Lake before turning around and retracing their route to the Caribbean.

For many cruise passengers, travelling through the Panama Canal is a bucket-list experience. Between 2004 and 2006, while working aboard one of those enormous cruise ships, I had the opportunity to experience the canal several times, and do both full and partial transits. Each passage brought its own moments of anticipation and wonder. Even after several transits, I would still find myself drawn to the deck, watching and waiting for the next stage of the journey to unfold.

It is a remarkable journey through a landscape that seems to change constantly—from open Caribbean waters to massive concrete locks, then into the enormous inland waters of Gatún Lake and eventually through the lush tropical landscape of the canal zone.

The approach begins slowly. Tugboats and canal locomotives help guide the ship into position, along with many other vessels waiting their turn. The canal is a carefully choreographed operation, with ships assigned their place in the sequence of transit.

The canal works rather like a gigantic water bridge. Ships are raised approximately 26 metres (85 feet) above sea level to the level of Gatún Lake and later lowered again on their descent towards the Pacific. Rather than relying on pumps, the locks use the natural force of gravity, with water flowing into and out of the chambers.

Standing on deck and looking down over the side, it is astonishing to see how little room there is between the ship's hull and the concrete walls. A vessel weighing tens of thousands of tonnes is being manoeuvred through a space that can appear almost impossibly narrow.

Alongside us, the “mules” chug back and forth. These electric locomotives run on rails beside the locks and are connected to the ship by lines, helping to keep it precisely centred and preventing it from scraping the walls. Their name is a reminder of an earlier era, when actual mules were used to haul and guide smaller vessels through lock systems.

The whole process is a fascinating demonstration of engineering and precision. From the deck, however, it feels less like watching a machine at work and more like being part of an enormous piece of living history.

A full transit takes around ten hours, although the exact time can vary according to traffic, scheduling and other canal operations.

Then there is the scenery. The dense, green jungle that surrounds the canal provides an ideal habitat for wildlife: iguanas, herons, monkeys and countless other birds and creatures hidden among the vegetation. On a couple of occasions I spotted a crocodile swimming almost alongside the ship.

At the Atlantic entrance to the canal lies the port of Cristóbal, on Manzanillo Island in Colón. The area has long been closely associated with the canal and remains an important maritime and cruise gateway.

Although Colón is home to the largest free-trade zone in the Americas, the Zona Libre is primarily geared towards wholesale trade rather than individual tourists. For cruise passengers, the Colón 2000 Cruise Terminal offers a much more convenient place to browse and shop, with its collection of duty-free stores, souvenir shops and stalls selling local handicrafts.

On days when cruise ships are in port, the atmosphere around the pier becomes particularly lively. Guna Indigenous artisans set up their stalls, displaying colourful handmade souvenirs and traditional crafts.

A Dream That Came at a Terrible Cost

The dream of cutting a waterway through Panama was not new, nor was it achieved without enormous cost.

Spanish explorers recognised the strategic possibilities of a route across the isthmus as early as the 16th century. Centuries later, the French were the first to make a serious attempt to turn that dream into reality. Beginning in the 1880s, they set out to construct a sea-level canal across the isthmus.

What they encountered was far more formidable than they had anticipated.

The jungle was relentless. The terrain presented enormous engineering challenges, while tropical diseases, particularly malaria and yellow fever, devastated the workforce. Thousands of workers died, costs spiralled and the project eventually collapsed amid financial scandal and bankruptcy.

The abandoned machinery and unfinished excavations were a stark reminder of the scale of the challenge. The dream of connecting two oceans had nearly been buried beneath the very jungle the builders had tried to conquer.

Then the United States took up the challenge.

In 1903, the United States secured control of the Canal Zone and began a new phase of construction. The approach was different, including a decision to build a lock canal rather than the sea-level canal originally envisaged by the French. Medical understanding and public-health measures also helped to fight against yellow fever and malaria.

After eleven years of extraordinary engineering, enormous excavation projects and relentless labour, the Panama Canal finally opened in 1914.

The achievement transformed world shipping. Vessels travelling between the Atlantic and Pacific no longer had to make the long journey around Cape Horn at the southern tip of South America. Thousands of miles could be saved, changing the movement of cargo, and eventually passengers, around the globe.

The canal's success, however, came with a complicated political legacy.

For decades, the United States exercised control over the Canal Zone, while many Panamanians argued that their country did not receive a fair share of the economic benefits generated by this enormously valuable waterway. Tensions grew over the years, accompanied by protests and periods of serious unrest.

Eventually, a gradual transfer of control began under the Tirrojos-Carter Treaties of 1977. On 31st December 1999, Panama assumed full control of the canal.

It was a remarkable moment: a waterway conceived centuries earlier, attempted unsuccessfully by the French, completed by the Americans and shaped by generations of Panamanians, had finally come under the complete sovereignty of Panama.

By the beginning of the 21st century, ships had grown dramatically in size, and the original canal could no longer accommodate many of the largest vessels. After years of planning and construction, a new set of locks opened in 2016 as part of the Panama Canal Expansion.

The new locks allow much larger Neo-Panamax vessels to make the transit, significantly increasing the canal's capacity and extending its importance in global shipping.

And so the canal continues to evolve.

For the cargo ships passing through today, it remains one of the world's most important commercial waterways. For those of us lucky enough to experience it from the deck of a cruise ship, however, it is something more personal: a slow journey through an extraordinary landscape, surrounded by reminders of ambition, sacrifice, engineering and history.
