The world’s very first floating McDonald’s, initially doubted for potentially diminishing Missouri’s picturesque waterfront, has recently regained attention with a series of captivating photos capturing its prime.

On March 11, 1980, the inaugural floating McDonald’s, fashioned to resemble a 19th-century riverboat, commenced operations on the St. Louis riverfront, moored just south of the renowned Gateway Arch.

Built on a repurposed cement barge, the 702-ton boat could seat an impressive 134 diners inside, with room for another 200 on its open-air decks.

Executives for the chain had high hopes, predicting the riverboat restaurant would flourish and bring in more than $100,000 in tax revenue annually. 

‘We don’t have anything similar to this anywhere in the world,’ exclaimed Pat Flynn, a senior vice president for the fast-food giant in 1980, during the grand opening celebrations as reported by the St. Louis Post-Dispatch.

On the other hand, locals worried that adding a fast-food chain to the riverfront would make the area look tacky and take away from the charm and natural beauty of the water.

Marilyn O’Neill wrote on a Facebook nostalgia post: ‘I thought at first McDonald’s would make the riverfront look cheap, but it was pretty cool for a while.’  

Despite the early criticism, the floating McDonald’s was a city staple for decades, delighting both locals and tourists – and leaving 80s kids with the magical impression that they were enjoying their favorite greasy meals aboard a yacht.

On March 11, 1980, the first ever floating McDonald’s (pictured) – designed to resemble a 19th-century riverboat – opened for business on the St. Louis riverfront, anchored just south of the iconic Gateway Arch

But after 20 years on the water, the iconic McBoat quietly vanished, leaving behind unanswered questions and a wake of nostalgia.

All that remains in its once-lively wake are historical photographs – snapshots from a time when spotting the boat was both routine and a whimsical highlight of waterfront trips.

The photos, captured in both black-and-white and color, feel like a glimpse into a totally different era. 

The only clear link to today’s modern McDonald’s is the iconic red and yellow color scheme that still remains widely recognizable.

Its fascinating history began in 1980, when Dr. Benjamin H. Davis Sr. made the floating eatery his fourth McDonald’s franchise, according to St. Louis Post-Dispatch.

The idea originated the year before, when Samuel Haynes, the company’s real estate manager at the time, announced that ‘McDonald’s is interested in special feeding’. 

‘If we can find a large group of people together, we should be able to feed them,’ Haynes told the St. Louis Post-Dispatch at the time. ‘The Arch draws more than 3million people a year.’

Initially, the company aimed to purchase space in the museum beneath the Arch, but the government was not willing to lease the space to private enterprises.

‘Then we looked down at the river and saw a lot of people taking advantage of it,’ Haynes added.

‘So we thought there was no reason why a company as adaptable and progressive as McDonald’s couldn’t do it.’

In 1979, a groundbreaking 25-year lease was signed, launching the very first floating McDonald’s – a bold venture that would change the dining landscape.

Measuring 185 feet in length and rising 50 feet high, the restaurant was nearly ready to launch with a 200-member crew, each outfitted in unique, custom uniforms designed exclusively for the floating location.

For those who experienced it, it became a lasting memory. ‘I remember taking my parents to the floating McDonald’s when they came to visit me from upstate New York,’ author Cameron Collins recalled in his book, Treasures of St. Louis.

‘My dad had never seen the Mississippi up close and personal, and tried to wade in it,’ he added.

‘I have memories of eating a Big Mac and taking in the Arch and hearing my mom yell at my dad, “Peter! Get away from the edge!”‘

Inside the floating McBoat, 19th-century paintings and murals lined the walls – creating an atmosphere meant to reflect the grandeur of the paddleboat era.

Still, for at least the next decade, the floating McDonald’s turned heads and won hearts – even among skeptics – eventually becoming a core memory for those who experienced it

But as if the stubborn champagne bottle had been a warning from above, the floating McDonald’s restaurant officially closed its doors on November 6, 2000 due to its structure – never to be seen in the St. Louis riverfront ever again

The floating McDonald’s restaurant officially closed its doors on November 6, 2000 – never to be seen in the St. Louis riverfront ever again.

McDonald’s issued a statement, explaining that the location closed ‘because the structure is in need of extensive renovation, which is financially not justifiable at the present’.

A further explanation never surfaced, and the attraction quietly disappeared.

What became of it after that final day remains undocumented – and shrouded in mystery.
