The milestone marks the arrival of the first ship in NCL’s Prima-class which will see six new ships delivered through 2027.
Present at the event was Frank Del Rio, president and chief executive officer of Norwegian Cruise Line Holdings; Harry Sommer, president and chief executive officer of Norwegian Cruise Line and Luigi Matarazzo, general manager of the Merchant Ships Division of Fincantieri.
Sommer said: "Today we usher in a thrilling new era in cruising as we celebrate the delivery of Norwegian Prima, the long-anticipated first ship in our extraordinary new Prima-class.
"She is a true testament to our guest first philosophy as well as our commitment to deliver unforgettable experiences that exceed expectations."
The vessel features the Ocean Boulevard, which wraps around the entire deck – and measures more than 44,000 square feet – as well as the Infinity Beach, which offers two infinity pools positioned close to water-level, while the Oceanwalk sees two glass bridges make guests feel as though they are "walking on air" over the water.
Launching this August, Prima will be the first major cruise ship christened in Iceland, commencing its eight-day inaugural voyage in the Icelandic capital of Reykjavik on 27 August sailing to Amsterdam.
Global popstar Katy Perry, who serves as Prima’s Godmother, will fulfil the longstanding maritime tradition of blessing and officially naming the ship, as well as performing during the christening ceremony.
Following its inaugural voyage, Prima will sail a series of eight-day voyages from Amsterdam and Copenhagen offering guests the opportunity to explore Northern Europe and the Norwegian Fjords.
