What should you do before letting someone else operate on your PWC?

Before allowing someone else to operate your personal watercraft (PWC), ensure they are familiar with its controls and safety features. Review the local laws and regulations regarding PWC operation with them, as well as any specific rules for your craft. Additionally, verify that they possess the necessary skills and experience to handle the PWC safely and responsibly. Finally, remind them of safety practices, such as wearing a life jacket and being aware of their surroundings.
