Firefighters battled two boat fires in Biscayne Bay on Wednesday afternoon.
The boats were docked in the 1900 block of Brickell Avenue.
Black smoke rose into downtown Miami as firefighters hosed down the flames.
The owner of one of the boats was replacing a piece of the engine when the fire started, said Miami Fire Rescue Capt. Alex Fernandez.
No one was injured.
It's unclear what started the fires.
