The Ultimate Abyss dry slide on the new Royal Caribbean ship Utopia of the Seas is officially the longest dry slide at sea. It is a whole 259 feet (79m) longer than the one on Wonder of the Seas (which previously held the record for being the longest dry slide at sea) and has a really scary long drop. This video shows what the whole ride on this slide is like from start to finish and includes me being ABSOLUTELY TERRIFIED. I was shaking with terror by the end and felt very dizzy and had trembling hands for a good few minutes afterwards! Would you be brave enough to ride it? This video includes POV footage of me riding the longest dry slide at sea
