What is the importance of a "leash" when using a personal watercraft?

The importance of a "leash" when using a personal watercraft lies in its crucial role in safety and control. When a rider uses a personal watercraft, the leash typically attaches to the rider's wrist or life jacket and connects to the craft. If the rider falls off or is thrown from the vessel, the leash ensures that the craft remains tethered to them. This prevents the personal watercraft from continuing on its course without the operator, which could lead to dangerous situations, such as the craft colliding with other vessels or obstacles, or becoming a hazard to others on the water. By maintaining control over the craft, the rider improves their safety while also enhancing the safety of others near the waterway.
