The Atlantica SuperSplash cars/boats do not turn like normal roller coaster cars. To change directions after climbing the lift hill there are two turntables separated by a small dip. The boats travel backwards through this dip. After a double-dip drop, the boats float and can complete the needed turn back to the station.
The Atlantica SuperSplash has magnetic trim brakes on the first drop which allows some control over the top speed and hence the amount of splash. So the ride can be adjusted depending on the season or weather.
