Water-related tragedies can happen in the blink of an eye. Playing it safe will help you return safely to shore. Whether you have your own personal watercraft or you're renting one for the day, the same safety guidelines apply.
Know what you're doing. Take lessons before you head out for the first time, or review the owner's manual periodically.
Wear a life jacket. Life jackets are just as important on personal watercraft as they are on boats and water skis. You may want to wear goggles to protect your eyes as well.
Be courteous on the water. Follow the traffic pattern. Obey no-wake zones. Be careful around swimmers, and keep an eye on other boats. Don't jump wakes or pass close to other boats.
Don't ride alone. Stick with a group of two or three, in case anyone has trouble.
Avoid alcohol. Don't drink alcohol while you're using a personal watercraft.
