Friends of Mike and Hannah Lynch said the father and daughter were part of a “united, vibrant, loving family” – with the teenager remembered as a “diamond in a sea of stars” and the tech mogul as a brilliant storyteller following an accident in Italy. Lynch was the creator of software giant Autonomy and had been cleared in June of carrying out a massive fraud related to its US$11 billion sale to US company Hewlett Packard. His daughter Hannah had recently finished her A-levels and was due to study at Oxford University.

Sasha Murray, chief stewardess of the Bayesian, said: “Those who knew her will know that Hannah was a diamond in a sea of stars. Bright, beautiful and always shining. “What most people may not have seen was the extraordinarily strong, deep and loving relationship she shared with her parents, whom she adored more than anything.

“While swimming with them she often said, if anything ever happened she would save them. “I have no doubt that the Irish, Latina fire that burns in her soul kept that spirited determination alive.” It is understood Murray was rescued after disaster struck the yacht earlier this week.

Susannah Gurdun, a close family friend of the Lynchs from Suffolk, shared a series of heartfelt stories about Lynch and who he was beyond being one of Britain’s biggest tech moguls. She said she first met him at a dinner party and was “daunted” at the prospect of sitting next to “some important big tech corporate alpha male”. “.
