Whitecap Racer will be a six-slide racing slide complex, featuring two tunnel sections, making them longest racing slides in the world. It's also said to have a timing system featured on many slides of this type, adding a competitive aspect.Breakers Edge Water Coaster:
Breakers Edge will be a water coaster, which I think is of this model
