Rockin' Tug is a flat tugboat ride manufactured by Zamperla.
The difference is that the Rockin' Tug has a friction wheel, while the Disk'O is powered driven.
Twenty four riders are loaded into a tugboat shaped gondola, in six rows of four.
The traveling version of the ride racks onto a single 28 foot trailer.
The most common one is a tug boat, but other versions include a longboat, a pirate ship, and a skateboard.
