Norwegian Cruise Line has announced plans for the world’s first at-sea tweetup for cruise-loving social media enthusiasts.

The SeaTweetup will be a three-night cruise around the Bahamas and is billed by the organizers as the world’s meeting for Twitter users at sea.

The cruise, departing Miami on November 18, will be hosted by Norwegian Cruise Line’s 2,002-passenger Norwegian Sky and is organized by, among others, social media TV show SocialBuzzTV and digital media consultants Social Esquire.

Norwegian Cruise Line (NCL) has revealed the new cabin designs to be used on its new ships set to come into service over the next three years.

The cabins, unveiled June 21, are described as “modern boutique hotel meets the sea” and are built on the experience of Norwegian over the past ten years — during which time it has launched ten new ships.

The two new vessels, currently codenamed Project Breakaway, are scheduled for delivery in April 2013 and April 2014, and can carry around 4,000 passengers.

The travel agency, which specializes in organizing large events at sea ranging from business meetings to theme cruises and reunions, picked ships with between 56 and 2,700 cabins, including the enormous Allure of the Seas.
