Karsten Borner, captain of a nearby boat, said after the storm had passed, the crew noticed the yacht that had been behind them had disappeared.
“We saw a red flare, so my first mate and I went to the position, and we found this life raft drifting,” he told Reuters.
His crew took on board some survivors, including three who were seriously injured.
Sounds like it might have flipped pretty quickly, rather than being a slow sinking:
Witnesses told Italian news agency Ansa that the Bayesian’s anchor was down when the storm struck, causing the 72m (236ft) aluminium mast to break in half and the ship to lose its balance and sink.
The ship’s unusually tall mast may have contributed to its sinking, according to Matthew Schanck, chair of the Maritime Search and Rescue Council.
He told BBC Radio 4’s Today programme that the mast acted almost like a sail in the strong wind “especially with it being so high”.
The extreme winds could have caught the mast and pushed the yacht over, he said.
One of the survivors, British tourist Charlotte Golunski, told Italian newspaper La Repubblica how she held up her one-year-old daughter Sofia to stop her from drowning.
She said the two of them and her partner James survived only because they were up on deck when the yacht sank.
