Singer Marc Anthony's Luxury Yacht Engulfed In Flames In Miami Marina

MIAMI (CBSMiami) – A luxury yacht belonging to singer Marc Anthony has been destroyed by fire in Miami.

A spokeswoman for Anthony told CBS4'S Peter D'Oench that he was "out of the country and not commenting" about the fire. She said everyone on board got off the yacht safely and "that is all that matters."

The 120-foot yacht caught fire Wednesday night near the MacArthur Causeway just off the west end of Watson Island.

"When crews arrived there was heavy smoke, a lot of flames on this yacht," said Miami Fire Rescue Capt. Ignatius Carroll Jr. He said there were 7 crew members onboard the yacht and no one was injured.

In a new interview at the site Thursday afternoon, Carroll said, "As crews first approached the marina they noticed the amount of fire and heavy black smoke and they knew it was going to be a significant challenge for their land crews and so fire boats responded."

He said Miami Fire Rescue deployed 50 firefighters and they received help from Miami-Dade Fire Rescue and Miami Beach Fire Rescue. Both of those agencies deployed boats.

Carroll said it took at least 3 hours to bring the blaze under control.

He told D'Oench "I think one of the biggest challenges was maneuvering around boats to keep them from being damaged. You have a marina with some very expensive yachts that are parked there."

Byron Chenaly, A deckhand who was on board another yacht just 40 feet away, said there were some tense moments.

"It was a bit harsh," he said. "At that point, people were trying to get off their yachts. It was quite dangerous for anyone on the yachts."

The flames were clearly visible from Downtown Miami as smoke filled the sky over the Island Gardens Marina.

The relatively new marina is part of the long-delayed development of Watson Island.

With City of Miami and Miami-Dade fireboats deployed, the fire was fought from dockside and from the water.

They kept water on the smoldering 120-foot yacht that was listing to its side.

They worked primarily in a defensive mode, containing the fire while protecting a number of other yachts moored nearby.

It's not known what caused this fire.

"The cause is under investigation right now," said Carroll. There is severe damaged caused by the fire last night and so the boat is three-fourths submerged underwater right now. So the next phase is to get the boat uprighted and dry-docked so investigators can continue their investigation."

Crime scene investigators were seen at the Marina.

Carroll noted that "When you have a fire this significant you want to make sure that all of the bases are covered and that's why the police department is brought in to make sure that this is no more than just a simple fire."

Because it is early in the investigation, Carroll said nothing had been ruled out so far.

TMZ reported the yacht had been for sale earlier this year.

It was reportedly a $7 million yacht, with 5 cabins with sleeping room for 12 people. It also had a barbecue area with a jacuzzi and docking stations for jet skis and satellite TV and had been the site of several gatherings and parties.

As seen in videos it was also a place where the singer had celebrated his passion for music. Those videos showed happier moments, with Anthony dancing with friends.
