Some 270 ships pass each week through the Panama Canal, but one now gives tourists the chance to experience the storied waterway on the Isla Morada, Al Capone’s legendary rum-runner.

The wooden ship, famous for smuggling liquor for the US mobster during the prohibition era, turned 100 this year and has been refurbished for guided tours of the canal’s locks and shoreline wildlife.

For $165 for a full 80-kilometre trip or $115 for a shorter version, visitors get to go through the canal, but are also transported back to a time when the boat supplied an underground world, shipping black market booze back to Capone’s Chicago.

The 94-ton, 96-metre-long Isla Morada began sailing in March 1912 under the name the Santana, and has since earned the distinction of having passed through the canal more than any other as the oldest vessel still on duty.

Capone (1899-1947) spared no expense on the original fittings of his rum-runner, giving it five luxury bedrooms, a lavish mahogany dining room, even a library.

The ship, “was used for smuggling rum and whiskey from the Dominican Republic and Cuba to an island in (Florida’s) Key West,” tourist guide Juan Carlos Villareal said.

After Capone was busted in the early 1930s for tax evasion and shipped off to the notorious Alcatraz prison in San Francisco Bay, the Isla Morada (‘Purple Island’) was requisitioned for use in World War II by the US Navy.

Brought back to Panama in the 1960s to serve as a floating hotel for sport fishing, it was later acquired by present owners Canal and Bay Tours, which run the canal cruises three or four times a week.

“I imagine all the things that happened on this ship,” said 21-year-old passenger Vanesa Lopez. It is thrilling to be “part of a history that a lot of people know from the movies,” she said.
