The crash happened on 87th Avenue near Lake Pleasant on Sunday.
Authorities say the boat was being hauled on a trailer with seven people inside. As the vehicle and boat turned a corner, the boat flipped and rolled over.
One person was rushed to the hospital with non life threatening injuries. Six others were being evaluated by paramedics but appear to have minor injuries.
"Don't ride in the back of the boat.. let them load the boat up to the trailer and hook it up and then you can get back into your vehicle. Don't even get on the trailer boat," said Captain Hector Mendez of the Peoria Fire Department.
It's not clear what caused the crash at this time.
