The Norwegian Edge is mostly focused on an “extensive” ship refurbishment of nine of the ships in the fleet, a process which began in October 2015 with a refresh of Norwegian Epic including many of its restaurants.

This was followed by Norwegian Gem and now a further seven ships are being lined up for a dry-docking with both guest-facing and technical enhancements scheduled.

Norwegian’s fleet has also updated its culinary offering while specialty menus are also being introduced.

The cruise line is also implementing plans to improve its privately-owned destinations including the development of a resort-style port of call Harvest Caye, Belize, and private Bahamian island Great Stirrup Cay.

 Norwegian Cruise Line president and chief operating officer Andy Stuart said: “Norwegian has a long history of investing in its fleet to offer guests the latest and greatest innovations, but the investment to raise our ships to The Norwegian Edge standard of excellence takes it to new levels.

“The new standards of The Norwegian Edge programme will entice our guests to return again and again to ships that will look and feel as if they were just delivered, with all new menus and new dining experiences, visiting incredible exclusive destinations that reflect the quality finishes, amenities and outstanding service found across the Norwegian fleet.”
