Carnival Mardi Gras will be a 5,200-passenger ship, and the largest vessel in the Carnival Cruise Line fleet when it debuts in August 2020. It will also be the cruise line's first ship to run on liquefied natural gas (LNG), a form of fuel that produces almost zero emissions.
The name of the ship is a throwback to Carnival Cruise Line's first-ever ship, which retired in 1993.
In another innovation for the line (and the cruise industry), Carnival Mardi Gras will feature the first roller coaster at sea. Dubbed "BOLT: Ultimate Sea Coaster", the ride will offer nearly 800 feet of twists, turns and drops with riders reaching speeds of nearly 40 miles per hour. (More timid riders need not worry, you'll be able to control the speed at which you go.) The track, located about 187 feet above sea level, will run around the perimeter of Carnival Mardi Gras' top deck and include a loop around the ship's funnel. The line plans to offer the attraction to cruisers for free, but said it might need to levy a surcharge if demand is too great.
Carnival Mardi Gras will also differ from the rest of the fleet in its exterior look; it will sport a classic navy blue hull with red and white accent stripes.
Mardi Gras will be based in Port Canaveral (Orlando) at a brand-new cruise terminal.
