The U.S. Coast Guard pulled three people from the burning Bliss, an 80-foot motor yacht, off of Miami Beach Saturday morning.
The Bliss caught fire at sea about 10 a.m., Petty Officer Sabrina Elgammal said.
Three people were on board, Elgammal said, but were rescued by the Coast Guard before suffering any injuries.
Elgammal said the cause of the fire remains under investigation.
The billowing smoke was visible from the shore of Miami Beach.
The yacht was capsizing late Saturday morning. Commercial salvage crews were expected to haul the charred remains from the ocean.
