Tech mogul Mike Lynch and daughter among six missing after yacht sinks

Divers scoured the wreck of a luxury yacht off Sicily's coast on Tuesday to find six missing people, including British tech entrepreneur Mike Lynch and his daughter, following an intense storm that sank the vessel on Monday.

The British-flagged Bayesian, a 56-meter-long superyacht, was carrying 22 people and anchored off the port of Porticello when it was hit by the fierce, pre-dawn storm.

Witnesses said the boat disappeared beneath the waves in a matter of minutes, baffling naval experts who said a boat as large as the Bayesian would have been designed to stay afloat for many hours despite taking on water.

Fifteen people escaped before it capsized and the body of one person who died was swiftly recovered. That left six passengers unaccounted for – Lynch and his 18-year-old daughter Hannah; Judy and Jonathan Bloomer, a non-executive chair of Morgan Stanley International; and Clifford Chance lawyer Chris Morvillo and his wife Neda Morvillo.

However, there was little chance of finding more survivors, rescuers said. "The fear is that the bodies got trapped inside the vessel," said Salvatore Cocina, head of civil protection in Sicily.

The boat was lying at a depth of 49 meters, giving divers only eight to 10 minutes at the wreck site before they had to resurface. Entering the boat was also proving difficult, said the fire brigade, which is leading the search operation.

"Inside the sailing ship, the spaces are very confined, and if you hit an obstacle it is very complicated to move forward, just as it is very difficult to find alternative routes," said fire spokesman Luca Cari.

One official, who declined to be named, said the divers had opened one access point, but this did not mean they could easily reach all parts of the submerged vessel.

Fire department diver Marco Tilotta told reporters the boat appeared to be intact and was lying on its right side. Divers had not ascertained whether the 72-meter-long mast had snapped somewhere along its length during the tempest.

Karsten Borner, the skipper of a boat that had been moored alongside the Bayesian, said the yacht flipped on its side soon after the storm hit and sank within two minutes, giving those below deck little time to get to safety.
