A 40-foot luxury yacht has been destroyed at a marina in Sydney's eastern suburbs after it went up in flames on Monday morning.
The cruiser, which appears to have been called Holderness Princess, caught fire just before 6.30am at the marina in Castra Place, Double Bay.
Boat destroyed in Sydney fire
A police investigation is underway after a fire engulfs a luxury boat at Double Bay Marina on Monday morning. Nine News.
"There are diesel tanks on board, so we're putting booms around. We don't want the waterways contaminated. That's the main focus now," NSW Fire and Rescue superintendent Paul Johnstone said.
At least 30 firefighters were on the scene and worked to protect surrounding boats.
"They would be under threat by radiant heat," Superintendent Johnstone said.
The fire was extinguished about 7am. There had been fears the yacht would sink.
The fact the boat was out on the water was also a challenge for firefighters who could not get their trucks close, he said.
"The trucks are at quite a distance from the water. So we have water supply issues."
NSW Fire and Rescue said the escape of diesel fuel from the yacht was of concern.
Resident Chris Sullivan, 48, said he first noticed the boat was on fire when he looked out the window of his house opposite the marina, about 6.30am.
"I saw some black smoke which I thought was a bit strange. I looked a bit further and saw that the cabin was on fire. I rang triple-0 and they already knew about it."
Mr Sullivan said the boat had been unattended and "in one of the moorings" and tied to a buoy for a few weeks.
He said he saw the owner bring the boat back into the marina to wash it about lunchtime on Sunday.
"Don't know who owns the boat but I saw the owner washing that particular boat yesterday. Had been out in one of the moorings for quite a while."
NSW Police said a crime scene had been established.
‘‘No one was injured. Police from Rose Bay are at the scene and are investigating," a police spokeswoman said.
Emergency services have told nearby residents to shut their windows and warned there would be a "very strong smell of smoke" across the eastern suburbs and city area.
