In 2019, 30 million travellers are expected to take a cruise, according to the Cruise Lines International Association. To compete for customers, cruise lines are squander billions to outdo each other with outrageous amenities and entertainment, from a high-tech planetarium at sea to an on-board race meeting track. Royal Caribbean alone is spending $200 million on a private island, CocoCay, in the Bahamas for guests, according to Bloomberg, and had a $115 conversion on Navigator of the Seas ship, which has the longest waterslide at sea at 800 feet.

The coaster allows two riders in a “motorcycle-like vehicle” that nations along a track 187 feet above seal level, offering 360-degree views of sea. “Kept at wholly throttle, the ride would take about a minute,” says Aprile. The ride is also quiet, he says.
