San Francisco’s Aquatic Park tells the story of maritime history’s greatest rescue mission

Karl Kortum’s $1 Bathhouse to Maritime Museum Empire

Karl Kortum saw ships vanishing and knew he had to act fast.

In 1950, after sailing on America’s last merchant voyage under sail, he got San Francisco to rent him an empty WPA bathhouse for just $1 a year.

The Maritime Museum opened in 1951 with artifacts from socialite Alma Spreckels. Then Kortum made his boldest move yet.

He bought the rotting Pacific Queen for $25,000 in 1954, restored her original name Balclutha, and with help from nine unions, brought the 1886 vessel back to life.

By 1955, this Scottish-built ship became the crown jewel of what would grow into the world’s largest historic fleet at San Francisco’s Aquatic Park.

The Last Sailor Who Saved Maritime History

Karl Kortum worked as a sailor on the final American merchant trip under sail in 1941. His ship, the Kaiulani, marked the end of an era going back hundreds of years.

This trip sparked Kortum’s love for saving maritime history.

Working the lines, climbing the rigging, and feeling the deck move gave him hands-on knowledge of a dying way of life that few others had.

War’s End Sparked His Preservation Mission

When World War II ended, Kortum came home with a clear goal. He noticed America’s rich sea history was quickly vanishing as old ships rotted or faced scrapping.

No one seemed to care about these floating pieces of history. Kortum knew these ships told key stories about America’s growth.

He began collecting sea items, photos, and papers while making a bold plan to create a museum that would save this forgotten history.

He Scored a Waterfront Palace for Just $1

In 1950, Kortum spotted a chance in San Francisco’s empty Aquatic Park bathhouse. The big Art Deco building sat unused on the waterfront.

Kortum talked city officials into renting him the building for just $1 per year. Some thought the deal seemed crazy, but Kortum had a clear plan for the forgotten bathhouse.

The city took a chance on his passion, giving him the keys to what would become a top-notch museum.

Society Lady’s Treasures Filled the Empty Halls

The San Francisco Maritime Museum opened on May 27, 1951. Kortum filled it with items given by Alma Spreckels, a rich socialite who loved sea history.

Her gifts gave the new museum instant respect. Visitors enjoyed ship models, sailing tools, and sea artwork shown throughout the old bathhouse.

The museum quickly became popular with locals and tourists who found this hidden gem on the waterfront.

A Rusting Ship Caught His Eye

Kortum wanted more than small items on display. He wanted something bigger to show visitors what real sailing ships looked like.

In 1954, he found the Pacific Queen rotting in the Sausalito mud.

The three-masted ship was once a proud cargo vessel named Balclutha, built in Scotland in 1886 to carry grain around Cape Horn.

Years of neglect left her in bad shape, but Kortum saw what she could become with proper care.

Kortum Bet Big on a Broken-Down Vessel

The price for the rotting Pacific Queen was $25,000, a huge amount for a small museum in 1954. Many thought Kortum crazy for wanting to buy what looked like floating junk.

But he knew the ship’s true worth went beyond money. Kortum got the funds and bought the vessel, quickly changing her name back to Balclutha.

This purchase started what would grow into an amazing group of historic ships.

Nine Unions Joined Forces to Save the Ship

The Balclutha needed major repairs before visitors could safely board her.

Kortum got help from nine different sea worker unions whose members still recalled the sailing days. Volunteer shipyard workers gave thousands of hours to fix the vessel.

They replaced rotten wood, fixed the rigging, and redid the cabins. The fix-up became a community project that brought together people from across the sea industry.

Crowds Flocked to Tour the Restored Treasure

On July 23, 1955, the Balclutha opened for public tours. Visitors lined up to board the fixed-up sailing ship.

Many stepped onto a real tall ship for the first time.

Children ran across the wooden decks while parents looked up at the huge masts reaching toward the sky.

The Balclutha quickly became the star of the maritime museum, bringing in thousands more visitors than the indoor displays alone.

More Historic Ships Found Safe Harbor

The success of the Balclutha pushed Kortum to add more historic vessels. Over the years, he added the ferry Eureka, the schooner C.A. Thayer, the tug Hercules, and other key ships to what became the San Francisco Maritime National Historical Park. Each ship showed a different part of sea history.

Together, they formed the largest group of historic ships in the world, giving visitors a full look at America’s ties to the sea.

His Movement Saved Ships Around the World

In 1963, Kortum started the National Maritime Historical Society to spread his work beyond San Francisco. He traveled worldwide, helping communities save their own sea treasures.

His know-how helped rescue the Falls of Clyde in Honolulu, the Great Britain in Bristol, and the Wavertree in New York. Kortum called it “sprinkling maritime museums all over the globe.”

His work created a worldwide network of people who shared knowledge and methods.

The Man Who Preserved Our Seafaring Past

Karl Kortum earned recognition as “the leader of the historic ships movement worldwide” before his death in 1996. His work transformed how we preserve maritime history.

From that first $1 lease of an empty bathhouse, he created a model for saving historic vessels that continues today.

Dozens of ships that would have otherwise been lost now serve as floating museums thanks to his pioneering efforts.

The bathhouse where it all started remains the heart of San Francisco’s maritime district, a testament to one sailor’s vision.

Visiting Aquatic Park, California

You can explore Karl Kortum’s maritime legacy at Aquatic Park’s free Maritime Museum, housed in a 1936 WPA bathhouse at 900 Beach Street.

The museum showcases Hilaire Hiler’s original murals and mosaics while telling the story of Kortum’s ship preservation work. Visit the Visitor Center at 499 Jefferson Street for Pacific maritime exhibits.

The museum opens daily 10 AM to 4 PM, though historic ships like the Balclutha are temporarily relocated during pier renovations through 2025.
