There were 12 guests on board the £30m Bayesian superyacht when it sank off the coast of Sicily after being hit by a freak tornado.
Here the Mail looks at who was on board the ship when the disaster struck:
Mike Lynch: MISSING
The 59-year-old tech mogul has an estimated net worth of £852 million.
Raised in Ilford, east London, by Irish parents, he made millions after setting up software company Autonomy in 1996.
It was the father of two who gathered the group together to celebrate his recent acquittal of charges in the United States over the yacht.
The Cambridge graduate had faced fraud and conspiracy charges after selling Autonomy for £9bn to US giant Hewlett Packard in 2011.
He owns a multi-million-pound ivy-covered house in Chelsea, west London. He has received numerous awards, including an OBE for services to business in 2006.

The teenager received awards for excellence in English, religion and philosophy, as well as a special William C Smith Prize for poetry.
Her friends described her as a “supernova,” kind and gentle, intellectual and a staunch feminist.

The 35-year-old British mother was travelling on the yacht with her partner, James Emsley, 36, and their one-year-old baby, Sofia.
The Oxford graduate is a partner at Dr Lynch’s Invoke Capital and has worked there since 2012.

Domenico Cipolla told Italian media: “She is very bright and communicates with a look. If she were two or three years old she would be at risk of trauma, but I think she will forget about this.”
