Norwegian Cruise Line Holdings has revealed further details of its upcoming newbuilds.

Coming from the Fincantieri shipyard, the new vessels are part of an eight-ship order placed earlier this year.

Set to be delivered between 2030 and 2036, the new vessels for Norwegian Cruise Line will have a new design and have grown in size since the initial announcement.

According to information shared during the company’s second quarter earnings presentatino, instead of 200,000 tons, the four vessels will have approximately 225,000 tons, with a capacity for roughly 5,100 guests each.

The new ships will be approximately 38 percent larger than the company’s largest vessel, the 2019-built Norwegian Encore.

With numbers similar to Royal Caribbean’s Oasis-class, which range from 220,000 to 231,000 tons, Norwegian’s new ships will also be among the largest in the world in terms of tonnage.

In addition to the new class, Norwegian Cruise Line’s orderbook also includes four additional Prima-class ships.

Part of a previous six-ship order, the lineup includes the Norwegian Aqua, which is set to enter service in 2025.

Slightly larger than its 143,000-ton two sister ships, the Norwegian Prima and the Norwegian Viva, the 156,000-ton vessel will be able to accommodate up to 3,550 guests.

After a sister ship to the Aqua, Norwegian is taking delivery of two methanol-ready Prima vessels in 2027 and 2028.

The green vessels will see further size and capacity growth.

In its second quarter earnings call, Norwegian Cruise Line Holdings also confirmed numbers for the new vessels being built for Oceania Cruises and Regent Seven Seas Cruises.

Following the 68,000-ton Allura, which is set to enter service in 2025, Oceania is set to take delivery of two 86,000-ton ships.

With a capacity for 1,450 guests, the newbuilds will be the largest in the fleet for the upper-premium cruise brand.

Also planning a new ship class, Regent is set to take delivery of the 77,000-ton Seven Seas Prestige in 2026. The 850-guest vessel will be followed by a yet-unnamed sister ship in 2029.
