<p>The future of NCL Corporation's (NCL) 150,000 gross ton F3 innovative new-build due out in early 2010, seems to be hanging in the balance, Cruise Critic.com reports. </p><p>Just two days after reports surfaced suggesting significant contractual disputes between NCL and Aker France, the yard responsible for F3's construction, talks seem to have broken down further. Seatrade Insider, an industry publication, is reporting that Aker is actually shopping the project. </p><p>According to the report, Carnival Corp &amp; PLC and Royal Caribbean Cruises Ltd and MSC Cruises, have all been contacted. The NCL-Aker fallout is said to stem from disagreements over the cost of altering certain specs on the vessel, which has been under construction for months (keel was laid back in April). </p><p>The chance of another line picking up the project seems highly unlikely, given the unusual nature of the F3 design -- structurally unique curved wave cabins, no main dining room, no main theater -- which represents a dramatic shift away from more traditionally designed ships. Seatrade's source notes that if another line agreed to take on the project, a lot of changes would need to be made. </p><p>Aker Yards won an order for two similar vessels from NCL in September 2006. NCL later decided not take up an option for the third ship.</p>
