From what I am seeing in the press releases, NCL has laid the first piece of steel for their first F3 Class ship (Unnamed)-at the Aker shipyard in France. She will weigh in at 150,000 tons (4500 passengers) and shall be the largest freestyle cruise ship. No announcements as to what her special features shall be were made.
Edit: Please continue in this earlier thread on the topic. Thank you. RF
