How Old Do You Have to Be to Rent a Jet Ski in Florida?

To rent a jet ski in Florida you have to be at least 18 years old, because the rental agreement is a legal contract and state livery law bars facilities from leasing a personal watercraft to anyone younger.¹ Driving one is a separate question with a lower floor: a 14-year-old can legally operate a jet ski if they meet Florida’s boating safety requirements, but they still can’t be the person who rents it.² That split is what trips families up at the dock, so here is how each piece actually works.

Why the Rental Age Is 18

Florida calls rental shops “liveries,” and state law requires them to collect a written rental agreement from you. The agreement has to include your name, address, date of birth, how many people will be on the watercraft, a return time, and an emergency contact.¹ Signing it is the problem for anyone under 18. No shop in Florida can hand over a jet ski to a minor as the renter, and parental consent or a signed waiver does not change that. The facility keeps your signed agreement on file for at least a year, and law enforcement can inspect it.

Bring a valid government-issued photo ID that shows your date of birth. A driver’s license or passport is standard.

Can Someone Under 18 Ride?

Yes, with limits. Anyone 14 or older can operate a jet ski in Florida as long as they meet the state’s boating safety education requirement.² In practice that means a parent or another adult signs the rental agreement and takes legal responsibility, and the teenager drives.

Children under 14 cannot operate a jet ski in Florida at all. There is no supervision exception and no parental-permission workaround. Florida law also makes it illegal for an owner or renter to knowingly let a child under 14 drive one.²

The Boating Safety Card

Anyone born on or after January 1, 1988, must complete an approved boating safety course before operating any motorized vessel in Florida, jet skis included.³ If you were born before that date you are exempt from the course, though every other rule on the water still applies to you.

Pass the course and the Florida Fish and Wildlife Conservation Commission (FWC) issues you a Boating Safety Education Identification Card. You have to carry it along with a photo ID while riding, and hand both over if law enforcement asks.³ Out-of-state visitors can use a card from their home state if that state’s course meets or exceeds Florida’s standards.⁴

Operating without valid credentials when required is a noncriminal infraction. If you get cited but can show a valid card at or before your court hearing, the court can dismiss the case and charge a dismissal fee of up to $10.⁵

Permanent Card vs. Temporary Certificate

For the permanent card, finish an FWC-approved course that meets the National Association of State Boating Law Administrators (NASBLA) minimums.⁶ Most providers offer it online, it takes a few hours, and the card is good for life.⁴

If you’re a visitor or just want to try jet skiing once, Florida sells a temporary certificate instead. It’s valid for 90 days. You take a 25-question exam, need 19 correct to pass, and the fee is typically under $10.⁷ Some liveries and marinas are authorized to give the exam themselves, so a rental shop may be able to certify you on the spot.⁴

Supervised Operator Exemption

One narrow exemption exists. A person who would otherwise need the card can skip it if they’re accompanied by someone at least 18 years old who holds a valid card (or is personally exempt) and is actively supervising the operation.⁴ The supervisor is on the hook for any violations. On a jet ski this realistically means the supervisor rides as a passenger, since most machines only seat two or three people.

What the Rental Shop Owes You

Florida regulates liveries more heavily than most renters realize. Every rental facility must hold an FWC permit, carry valid insurance, and keep enough Coast Guard-approved life jackets on site to cover the capacity of every vessel in its fleet.¹

Before handing you the keys, the shop is required by law to give you pre-ride instruction covering:

How the specific jet ski works, including throttle, steering, and braking characteristics.
Safe operation and the basic navigation and right-of-way rules on Florida waterways.
Local hazards such as shallow areas, restricted zones, and heavy boat traffic where you’ll be riding.
Emergency procedures if you capsize, fall off, take on water, or hit another vessel.

You sign a written statement confirming you received each part of that instruction, and the facility keeps the form on file for at least 90 days.¹ A shop that skips the safety briefing is breaking state law.

The Rules You’re Agreeing To Follow

Once you sign, the on-water rules are on you. A few matter more than the rest.

Every person riding on or being towed behind a jet ski has to wear a Coast Guard-approved life jacket the entire time. Unlike on larger boats, stowing one within reach isn’t enough on a personal watercraft, and inflatable PFDs don’t count — only traditional foam-style jackets are legal.²⁸

If the jet ski has a factory-installed engine cutoff switch, and virtually all modern ones do, you must clip the attached lanyard to yourself, your clothing, or your life jacket while riding.² Federal law reinforces it: any operator of a motorized recreational vessel under 26 feet must use the cutoff link when the boat is on plane or above displacement speed.⁹

Florida also bans jet ski operation between a half hour after sunset and a half hour before sunrise, with no recreational exceptions.² Jet skis don’t carry navigation lights, which is why the law keeps them off the water after dark.

Boating under the influence applies to jet skis the same way it applies to any other vessel. The legal blood-alcohol limit is 0.08, the same as for driving a car. A first conviction carries a fine between $500 and $1,000 and up to six months in jail, with steeper penalties if your BAC is 0.15 or higher or a minor is aboard.¹⁰ Vacation mindset is where this one bites people. Open-water drinking rules are not looser than road rules.
