The ship, tentatively named Silver Moon, will accommodate 596 passengers and is due for delivery on 2020.
The new build will be the sister ship of Silversea’s latest vessel, Silver Muse. It will take the line’s fleet to 10 ships and will have mechanisms in place to prevent air and water pollution and measure noise levels.
Manfredi Lefebvre d’Ovidio, chairman of Silversea, said: “Based on the high praise Silver Muse has earned with our guests, we are eager to build on our flagship’s success and move forward with a sister ship, which will bring us closer to fulfilling my father’s dream of a 12-ship fleet.
“We pride ourselves on delivering an outstanding luxury cruise experience, and are delighted to partner once again with expert luxury shipbuilder Fincantieri as we continue to grow and evolve our fleet.”
