American luxury cruise line Seabourn has held a keel-laying ceremony for its new purpose-built expedition vessel at the T Mariotti shipyard in San Giorgio di Nogaro, Italy.

Named Seabourn Venture, the new cruise ship is expected to enter service in June 2021.

Seabourn president Richard Meadows said: “This milestone is always an exciting moment, as it represents another step forward in a new chapter of expedition cruising for Seabourn and our guests.

“I am incredibly proud of the way our fleet has continued to evolve and deliver over more than three decades of the finest cruise experience on the seas. As Seabourn Venture continues to take shape, we look forward to revealing more details and highlights of her progress over the months to come.”

Another company’s cruise ship is expected to start service in May 2022.

Both ships will be able to operate in various weather conditions and will comply with PC6 Polar Class standards.

Featuring modern hardware and technology, each ship will have two custom-built submarines on board.

The submarines will provide passengers with a view of the surroundings under the ocean’s surface.

The cruise line hired hospitality designer Adam Tihany for the public areas and all categories of the ship’s 132 oceanfront veranda suites.

Mariotti managing director Marco Ghiglione said: “T Mariotti’s commitment and dedication to the construction of the first ultra-luxury expedition vessel for Seabourn is high and for this, I would like to thank all those who have long been working on this ambitious project.

“After an intense design phase, this marks a new step forward in the process of building the ship, marking the result of a well-established collaboration with a major partner like Seabourn.”

The cruise line manages a fleet of five ultra-luxury ships. It is also part of World’s Leading Cruise Lines that includes Holland America Line, Princess Cruises, Carnival Cruise Lines, Cunard Line, Costa Cruises, AIDA and P&O Cruises UK.
