The yacht was undergoing maintenance works in a dry dock, which is managed by Ente Bacini, when the incident occurred at around 3pm local time on September 10. The yard said the yacht listed during the "pumping out phase of dry docking" as the yacht was being relaunched. Amico & Co said this was "for reasons that are yet to be ascertained."
Emergency services attended the scene, including the coastguard, fire services, Ente Bacini and Amico & Co emergency responders which, the yard said, "intervened immediately."
A total of six crew members sustained "slight injuries" in the incident, which saw five of them taken to hospital for further treatment. All five were later released during the evening, the yard said.
Amico & Co said the yacht "is now in a stable condition and inspections and operations to secure it are ongoing."
It comes after the yacht's management company, Döhle Yachts, also gave a statement on the incident. "Nero did not contact the dock wall and appears to have suffered only minimal damage," it said. It is expected that the yacht will be back in the water and ready to charter soon.
Surveys and inspections assessing the extent of the damage are still ongoing. The cause of the accident is also under investigation.
Delivered in 2008, Nero is a popular charter yacht and was designed by Neil Taylor with naval architecture by Imt Marine Consultants. The yacht was inspired by J.P Morgan's Corsair IV and commissioned by Taylor. He originally set out to restore a true classic, but when an acceptable donor couldn't be found he decided to build a replica.
In 2016, Nero underwent an extensive eight-month refit at MB92 after a change in ownership, which included a full repaint and brand new interiors by Italian designer Laura Pomponi. It became one of the largest superyacht refits the yard had ever undertaken. Today, the yacht still captures the spirit and elegance of the roaring 1920s but with state-of-the-art technology and a much more contemporary - and charter friendly - interior.
Accommodation on board is for a total of 12 guests in five cabins plus a spectacular owner's duplex suite with a separate lounge, study, and his and hers bathrooms. Other highlights include a dedicated spa with an onboard masseuse, beautician and fitness instructor, and a 5.7 metre resistance pool on the foredeck. Further accommodation can sleep up to 20 crewmembers.
