The offer for travel agents and the Venetian Society (Silversea’s loyalty programme) is available until 6 January 2022.
Silver Nova, with a planned summer 2023 launch, will reportedly be the first low-emissions luxury cruise ship with "advanced" hybrid technology, such as fuel cells.
The inaugural season for Silver Nova will commence on 15 July 2023 and include sailings ranging from seven to 23 days.
The ship’s 10-day maiden voyage from Southampton to Lisbon will call in Saint Malo, Bordeaux, Bilbao and Lisbon.
During its inaugural season, Silver Nova is scheduled to offer a total of 20 journeys in the Mediterranean, Caribbean and South America, as well as a transoceanic crossing.
Roberto Martinoli, president and chief executive of Silversea Cruises, said: "We are thrilled to offer our guests a new way to travel with this evolution of luxury and sustainability.
"Silver Nova represents more than a new luxury ship; its launch advances responsible cruising and new leadership and innovation in the cruise industry."
