A new cruise ship, the Norwegian Bliss, will have its own open-air electric kart track, where passengers can race against each other in front of ever-changing scenery.
Scheduled to go into service in 2018, the Norwegian Bliss is 325m-long, weighs 168,800 tonnes and when full will be a floating holiday resort for 4,250 passengers, along with 2,100 crew.
As well as the usual cruise ship luxuries like an aqua park, spa, restaurants and daily entertainment, the Norwegian Bliss' party trick is a 1,000ft go-kart track on the top deck.
The electric karts are claimed to race at up to 30 miles per hour, plus a "turbo boost" on each 30-second lap. Passengers are able to compete on novice, intermediate and advanced levels to ensure everyone gets a fair and close race.
Embedded below is a 360-degree video demonstrating what a lap of the circuit will look like.
Another high-tech exclusive aboard the ship is an open-air laser tag arena, designed to look like an abandoned space ship.
Finally, an aqua park includes two multi-storey waterslides and a tandem slide where passengers can race each other through tubes over 360 feet long, each with translucent sections offering a view of the ocean below.
Norwegian Bliss goes into service in April 2018. It will offer weekly cruises around Alaska in the summer, before heading to the Caribbean for the winter.
