Nine people were rescued from a sinking boat near Broad Causeway on Sunday afternoon, Miami-Dade Fire Rescue officials said.
A man who authorities said had a “cardiac episode” after arriving at Haulover Marina was taken to an area hospital by a ground rescue unit.
It’s unclear what caused the boat to start sinking.
The boaters were wearing life vests, officials said.
A dog was also on the boat at the time of the incident.
