A Boston Duck Tours amphibious vehicle churning through the Charles River was evacuated today after the engine began smoking, the State Police said.
Employees aboard the duck boat noticed the smoke at about 12:15 p.m. and suspected a radiator hose might have burst, said Bob Schwartz, director of marketing and sales for Boston Duck Tours.
Schwartz said employees did not see any flames.
No injuries were reported, said State Police spokesman David Procopio.
A State Police boat was on the water near the Museum of Science when it saw the duck boat in distress, Procopio said. Passengers were offloaded onto the State Police boat and brought to shore, he said.
According to US Coast Guard requirements, emergency procedures must be explained before every duck tour, Schwartz said.
Another duck boat towed the disabled vessel to land, where it is currently being inspected, Schwartz said.
“It’s like any other type of vehicle,” Schwartz said. “Sometimes it breaks down.”Globe correspondent Melissa Hanson contributed to this report. Jasper can be reached at email@example.com or on Twitter @Jasper_Craven
