The next step is to swim back to the PWC's stern and board it again.

When using a personal watercraft (PWC), also known as a water scooter or jet ski, for enjoyment, the rider sits or stands on the craft rather than inside it like they would in a boat. PWCs come in two different design types, the first and most well-known of which is the runabout or "sit down," which is used mostly while the rider is seated and often accommodates two or more people. In the second style, the rider operates the watercraft while standing up. The stand-up designs are designed for a single rider and are more frequently utilized for racing, stunt riding, and competitions.
