European Personal Watercraft Championship in Crikvenica
Jet Ski is the brand name of a personal watercraft manufactured by Kawasaki. It was the "first commercially successful" personal watercraft in America, having been released in 1972. The term is sometimes used to refer to any type of personal watercraft.
Though the proper noun "Jet Ski" is a registered trademark of Kawasaki, the common noun "jet ski" refers to small recreational watercraft. The Oxford English Dictionary records the term in use in 1961 to describe the aquatic motorbike, and in 1948 to designate a jet-propelled aircraft equipped with skis.
