A personal watercraft, also called Jet Ski or water scooter, is a primarily recreational watercraft that is designed to hold only a small number of occupants, who sit or stand on top of the craft, not within the craft as in a boat. From Wikipedia
A recreational jetski outing near Wiesbaden led to a multi-agency search after a husband mistakenly reported his wife missing, only for her to be found safe at their destination.
