The FOX article mentions the Hot Springs accident (very bottom) you mentioned and so does WIKI.
It must be one of the worst ones involving one of these Duck Boats.
Also it seems these Duck Boats accidents are not confined to just on water.
According to WIKI:
On May 8, 2015, a Ride the Ducks boat struck and killed a woman crossing the street in Philadelphia, Pennsylvania's Chinatown section. Witnesses at the scene say that the woman was distracted by her handheld tablet device and walked into the street against the red light and was struck while in the boat's front center blind spot. The incident is still being investigated.
On September 24, 2015, a Ride the Ducks vehicle in Seattle, Washington crashed into a charter bus on the Aurora Bridge, killing five passengers on the bus, critically injuring eight, and seriously injuring eight more.
I found an old article about it with photo of the collision:

On April 29, 2016, in Boston, Massachusetts, a 29-year-old woman was killed after the motor scooter she was operating collided with a Duck Boat, as both vehicles turned onto Beacon Street adjacent to the Boston Common.
Also one of the water accidents according to WIKI, if I am already not getting on a converted bus to boat, I definitely will not get on a Ford F-350 converted to a boat:
On June 23, 2002, the Lady Duck, a custom-built vehicle converted from a Ford F-350 pickup truck, sank while on a cruise on the Ottawa River in Ontario, Canada. Six passengers, the driver, and the tour guide escaped, but four passengers were trapped under the sunken vehicle's canopy and drowned. A review found problems with regulating such vehicles and defects in the makeshift design and the emergency procedures.
