The "Category 6" water park on Royal Caribbean's Icon of the Seas features six record-breaking slides with specific safety requirements. For the most intense slides, Frightening Bolt (the tallest drop slide at sea) and Pressure Drop (the first open freefall slide at sea), riders must be at least 48 inches (122 cm) tall. The mat-racing slides, Storm Chasers, and the family raft slides, Hurricane Hunter and Storm Surge, have a slightly more accessible height requirement of 42 inches (107 cm). In addition to height, there are weight restrictions; individual slides typically accommodate riders up to 300 lbs, while the family raft slides have a combined weight limit of around 550 lbs. Children under 14 years old generally require adult supervision within the water park area, regardless of whether they meet the height requirements. These rules are strictly enforced by onboard lifeguards to ensure the safety of passengers during high-speed maneuvers.
