Navigator of the seas will soon have the largest waterslide onboard.

You may have heard about the biggest rollercoaster at sea? Well, now Royal Caribbean has just announced that they will be installing the worlds longest waterslide on their newly renovated cruise ship, Navigator of the sea.

The waterslide will allow a two-person raft through more than 800 feet of hills, drops and straightaways including a section that extends over the side of the ship for a unique thrill ride.
