Today is National Roller Coaster Day and Carnival Cruise Line is getting its second BOLT: Ultimate Sea Coaster on Carnival Celebration ready for thrill seekers. A new video clip from the shipyard shows the roller coaster’s newly installed car on its track in preparation for test runs set to happen this week.

Carnival Celebration’s construction is being completed at Meyer Turku in Finland and will introduce Carnival’s hometown homeport of Miami to yet another modern maritime marvel when it brings BOLT, and many other stunning Excel-class innovations, to PortMiami in the fall. The first BOLT, which carries the distinction of also being the first-ever roller coaster at sea, is already thrilling guests every day on sister ship Mardi Gras.

BOLT is an all-electric coaster featuring a two-person car traveling at speeds of up to 40 miles per hour on an 800-foot track full of drops, twists and turns 187 feet above the water line. Among other awards, the coaster was recognized by Popular Science with its “Best of What’s New” engineering award last year.

“The recognition this incredible attraction has received since its debut on our flagship last year highlights the tremendous work that went into making it a reality, but the most important thing about BOLT is, simply, it’s fun. It embodies the great lengths we’ll go to for our guests’ good time, and I’m eager to see this next coaster in service when Carnival Celebration begins sailing,” said Christine Duffy, Carnival’s president.

Technicians have conducted shoreside test runs of the new BOLT, which was first assembled at Maurer Rides in Munich, Germany for initial testing and then reassembled atop Carnival Celebration in Finland over the past several weeks.

“At Maurer, we build and deliver excitement and we will deliver just that when BOLT debuts on Carnival Celebration. We can’t wait to present this breathtaking ride to Carnival’s guests,” said Marco Hartwig, project manager at Maurer Rides.

Carnival Celebration will offer year-round, seven-day Caribbean sailings beginning with its inaugural cruise on Nov. 21 after debuting from the redesigned Terminal F at PortMiami. Carnival Celebration will join sister Mardi Gras as the second Carnival ship in the fleet powered by a Liquefied Natural Gas (LNG) propulsion system, part of Carnival Corporation’s pioneering green cruising platform.
