It's not just a boat ride - it's a theme-park style heart pounding adventure. The New Zealand-style boats can zip across just four inches of water at speeds up to 55 mph, and can perform thrilling maneuvers and 360-degree turns. For a calmer experience, try the Sea Spis – personal, jet ski sized glass bottom boats, or experience the Key West yacht club with all its perks and amenities. White Knuckle can provide transportation to all the water fun. The more people you pack onto these thrill rides, the more fun you'll have (the weight helps to push the water around).
