The cruise ship water slide on Royal Caribbean’s Icon of the Seas made headlines this week following a dramatic incident that left one passenger injured. On August 7, 2025, while sailing in the Caribbean, a glass panel on the ship’s Frightening Bolt water slide unexpectedly shattered as a guest was riding through it, releasing torrents of water and causing panic among nearby passengers. The injured passenger received immediate medical attention from the cruise staff and is currently being treated for their injuries. In response, Royal Caribbean has closed the water slide for the remainder of the voyage as they conduct a thorough investigation into the cause of the malfunction.
The Icon of the Seas holds the distinction of being the world’s largest cruise ship and boasts the largest waterpark at sea, Category 6. This waterpark features six thrill-packed water slides, including the Frightening Bolt—the tallest drop slide at sea—and several other innovative rides such as the Pressure Drop, the first open free-fall water slide at sea, along with mat racing slides called Storm Chasers. All these slides are included in the cruise fare, allowing guests unlimited access during their trip.
This recent accident has not only caused concern among passengers but also highlights the importance of rigorous safety protocols for thrill attractions on cruise ships. The rapid response by Royal Caribbean’s medical team reassured guests, and the ship is scheduled to return to its home port in Miami on August 9 after completing its Caribbean itinerary.
Apart from the Icon of the Seas, other cruise lines are also intensifying their water slide offerings with new and exciting projects. For instance, Norwegian Cruise Line is planning a vast new waterpark called Great Tides, set to open in summer 2026 at their private island Great Stirrup Cay. This new park will feature 19 slides, including racing slides, inner tube rides, and body slides, complemented by conveniences like an inner tube conveyor lift, designed to maximize fun without fatigue.
MSC Cruises continues to innovate too, with multiple ships outfitted with Aqua Parks that integrate virtual reality with traditional slide experiences. These parks boast multiple massive slides and interactive splash zones, enriching the cruise experience with high-tech thrills.
The surge in investing in water parks and water slides aboard cruise ships clearly reflects the growing demand for adrenaline-pumping aquatic adventures on the high seas. However, the recent accident at Icon of the Seas serves as a reminder of the fine balance cruise companies must maintain between innovation, excitement, and passenger safety.
For cruise enthusiasts planning their next vacation, the appeal of water slides at sea remains strong, offering unparalleled fun against the stunning backdrop of the ocean. Whether it’s racing down twin slides at MSC Seaside, testing courage on Icon of the Seas’ Frightening Bolt, or looking forward to Norwegian’s upcoming massive waterpark, these adventurous features deliver a splash of excitement to any cruise itinerary.
