What to Know
Duck boats are repurposed military vehicles. The same ones in the water today date back to World War II.

The "boats" are amphibious vehicles made by modifying military trucks. The ones in use today were built for use in World War II and were named with the acronym DUKW, which led to the nickname "duck boats."
Duck boats were used during the Normandy invasion on D-Day to bring troops ashore, and some were used again in Korea.
In recent years some businesses have re-purposed those same, decades-old vehicles into sightseeing attractions that drive from land into rivers and lakes.
The boats sit low in the water, with waves lapping just outside the boats' windows.
In 1999, 13 people drowned while riding a duck boat in Hot Springs, Arkansas. That boat sank so quickly that no one aboard had time to put on a life jacket, the NTSB reported; its investigation found the boat had been inadequately maintained.

But a lawyer who represented the Philadelphia water crash victims said Friday that's not good enough.
The vehicles are "deathtraps operating on land and in the water," Robert Mongeluzzi said, reiterating his call for a national ban on duck boats.
“After this tragedy, we again ask, What does it take for tour operators to realize that they cannot value profit more than human life and public safety?" Mongeluzzi said in a statement.
