With seven new ocean cruise ships launching in 2016, including five of the largest-in-fleet, and four new ship classes, Cruise Critic, the world's leading cruise review site and online cruise community, offers a round up.

"New ships in 2015 included P&O Cruises' Britannia, the largest ship built for the UK market, and Norwegian Escape, the third largest ship in the world," commented Adam Coulter, UK Editor. "The trend of large ship launches continues in 2016, with Royal Caribbean delivering Harmony of the Seas, the world's largest ship, and five lines introducing the largest-in-fleet. These new additions indicate that cruise holidays are growing in popularity, and with the latest in onboard entertainment, activities, and dining options, there is much to capture the imagination of UK travellers, both existing cruisers, and newbies."
