The Disk'O (also known as Skater or Surf's Up) is a type of flat ride manufactured by Zamperla of Italy.
The ride is a larger version of a Rockin' Tug, also manufactured by Zamperla.
On a Skater or a Skater Coaster, riders sit on a rectangular platform with inwards facing seats.
On a Surf's Up, riders stand on a rectangular platform.
The platform moves back and forth along a halfpipe track while spinning.
