Four people were reportedly injured when a superyacht owned by Irish media mogul Denis O’Brien listed while being relaunched from a dry dock in Italy.

According to Boat International, the 90-metre Nero was in the process of being moved out of the dock at Amico & Co in Genoa yesterday (Tuesday 10 September) when a support panel apparently gave way, causing the vessel to list dangerously in the dock on its port side.

It’s not yet known what damage has been caused to the popular charter yacht, part of the 1920s-inspired Corsair range, which was purchased by Denis O’Brien in 2014 for around €40 million and underwent a significant refit in Barcelona in 2016.

A statement from Döhle Yachts, which manages Nero, says the yacht listed at a 30-degree angle but "did not contact the dock wall and appears to have suffered only minimal damage".

The statement added that there was no risk to the environment and "no serious injuries" were sustained, with all crew safely disembarking after the incident, which is under investigation.
