In pictures: This is what the first roller coaster on a cruise ship will look like

Carnival Cruises announced late last year that it would build the world's first roller coaster at sea.

This week, the cruise line released exciting new images of the new attraction and fresh details on how it will all work.

This all-electric thrill ride, called Bolt, puts you in the driver's seat of motorcycle-style vehicles on the track — how fast you go is in your hands.

Passengers will ride the 800-foot track up 187 feet above sea level to get the best views from the ship. An additional charge to board the coaster will apply.

You won't get the kind of speed or drops you might expect from the world's top theme parks. The top speed of the Bolt Ultimate Sea Coaster is just over 60 km per hour. For context, the world's fastest roller coaster goes at 240 km per hour.

Parents and tall people take note: passengers need to be at least 3"5 tall to ride — and shorter than 6"3.

If you're too tall or too short, don't despair, the Mardi Gras will also feature "Family Feud Live," where families can play the famous game show format.

The ship will be the largest in the Carnival Cruises fleet, with 20 decks and 5,200 rooms onboard.
