Looking at Navigator on Royal Caribbean's website it now says "Are you bold enough to chase the most exhilarating duo of The Perfect Storm℠ waterslides yet? Pair up to take on The Blaster℠ aqua coaster and come face to face with adventure on the Riptide℠ headfirst mat racer." Does anyone know more details about these new type of slides, the aqua coaster and mat racer?
