Donut usually takes place on a large body of water such as a sea, lake or river. One or more banana and donut riders tether their tubes to a powered watercraft such as a motor boat or a personal watercraft. The riders are then towed through the water by the watercraft. The speed and manner in which this occurs is usually dictated by the riders. Children are generally given a slow, tame ride while thrill-seeking teenagers will usually opt to be towed faster, even seeking to be pulled through choppy water or across wakes.
