Jet skis are small, personal watercraft designed for one or two riders. They are powered by an engine that propels the craft forward, allowing users to glide across the water's surface. Jet skis are popular for recreational activities such as racing, touring, and exploring lakes, rivers, and coastal areas. These watercraft operate by drawing water into the engine and expelling it through a nozzle, creating thrust. Jet skis are typically lightweight and maneuverable, making them easy to handle. Safety gear, such as life jackets, is essential for riders, and many regions require a boating license to operate them legally.
