Carnival Cruise Line’s soon-to-launch onboard roller coaster will feature cameras along the track and inside the motorcycle-inspired electric vehicles to capture passengers as they take the 40mph ride.

Bolt, which the US-based line claims is the first roller coaster at sea, is the centrepiece of the open-air recreation area on incoming LNG-powered ship Mardi Gras, due in August 2020.

Each vehicle will also have a digital speedometer display and speakers that produce sound effects on the ride along the 800-foot track.

Although the ride has a top speed of 40 mph, passengers can choose how fast they go.

Cameras will capture passengers on the ride as they take in 360-degree views and race 187-feet above the sea with drops, dips and hairpin turns.

“Combining the most talented designers, technicians and attractions professionals in the industry, we’ve taken fun to a whole new level with this amazing onboard experience.”
