A woman driving a motor scooter died Saturday after being struck by a “duck boat” amphibious tour vehicle loaded with passengers on a downtown Boston street, police said.

The woman, 29, was taken to a hospital after the 11:30 a.m. accident and died there a short time later, said officer Rachel McGuire, a spokeswoman for the Boston Police Department. A male passenger on the scooter suffered injuries that were not considered to be life-threatening and was also taken to a hospital, McGuire said.

The duck boat carried about 28 passengers, McGuire said. The vehicles visit sights on the streets of downtown Boston and then take tourists on the Charles River, McGuire said.

The woman’s identity and the cause of the accident were not released because the investigation was still underway, she said.

The vehicle was near the corner of Beacon and Charles streets, McGuire said. The busy intersection is home to the bar depicted in the “Cheers” television show and divides the Beacon Hill neighborhood from the Boston Common and Public Garden.

The fatal crash comes about eight months after four international college students were killed when a duck boat in which they were riding collided with a bus on a Seattle bridge.
