Morgan Stanley International Chairman Jonathan Bloomer and his wife; and Clifford Chance lawyer Chris Morvillo and his wife, are also missing.
Officials confirmed Monday that at least one person, the ship’s cook, had died.
Rescuers said Tuesday that there might be people trapped inside the cabins, especially considering the timing of the storm, but that they had so far been unable to check through the ship’s portholes.
“The operations are long and complex,” Italy’s national fire department, whose diving teams have been participating in the search, said on X.
Italy’s coast guard also said Tuesday divers were also using a remotely-operated underwater vehicle to aid in the search.
The Bayesian is owned by a firm linked to Lynch’s wife, Angela Bacares, who was one of the 15 people rescued Monday after it capsized near Sicily’s main city of Palermo in what Italian officials called a “violent storm.”
Built by Italian shipbuilder Perini Navi in 2008, the U.K.-registered Bayesian could carry 12 guests and a crew of up to 10, according to online specialist yacht sites. Its nearly 250-foot mast is the tallest aluminum sailing mast in the world, according to CharterWorld Luxury Yacht Charters.
Lynch, who was regularly described in U.K. media as “Britain’s Bill Gates,” was acquitted by a San Francisco jury of fraud charges stemming from the 2011 sale of his software company Autonomy to Hewlett-Packard for $11 billion.
