A luxury yacht captain is under investigation for manslaughter following the deaths of a British tech mogul and six others.

An investigation is underway by Italian prosecutors into the captain of the superyacht that sank off the coast of Italy last week, resulting in the death of seven people.

An investigation is underway for James Cutfield, a 51-year-old man from New Zealand, on charges of manslaughter and culpable shipwreck, according to Italian media reports on Monday.

Mike Lynch, his daughter Hannah, and five others died in the sinking of the Bayesian, while 15 others survived.

According to Franco Romani, a nautical architect who was part of the team that designed the yacht, the Bayesian was constructed to withstand any weather conditions at sea. He also stated that the yacht could have taken on water through an open side hatch on its left side.

The event was described as "extremely rapid" and could have been a "downburst," a localized, powerful wind that rapidly spreads out upon hitting the ground.

As per U.S. law, being under investigation does not necessarily mean that Cutfield is guilty or will face formal charges.

On Saturday, chief prosecutor Ambrogio Cartosio announced that his team will investigate all possible elements of responsibility, including those of the captain, crew, supervisors, and yacht manufacturer, in addition to confirming an investigation.

The Perini Navi-built luxury yacht, christened "unsinkable" by its manufacturer, was a 184-foot British flagship.

Six passengers were trapped in the hull, but the chef survived.

eSysman SuperYachts' YouTube channel, eSysman, spoke with Planet Chronicle Digital to determine the cause of the vessel's issues.

The host pointed out that while weather is taken into account in any voyage plan, predicting it with 100% accuracy is still not possible. The captain is ultimately responsible for the vessel.
