'Carnival' debuts world's first cruise ship roller coaster

If cruise ships don’t make you seasick enough, maybe Carnival’s latest gimmick will. 

It's just finished building the world’s first cruise ship roller coaster. 

It’s called ‘the Bolt’: it has an 800-foot-long track, goes more than 60-kilometres-per-hour at 180 feet above sea level. 

Two riders straddle it ‘motorcycle-style’ while it whips around the ship's smokestack.

See it in action (ride begins at 2:29).
