How Fast Can Jet Skis Go? What the Ride Feels Like in Miami

When you search this question you will see a lot of numbers, and most of them trace back to one piece of history. A Powersports Business article from December 2006 describes a gentlemen's agreement between personal watercraft makers and the U.S. Coast Guard. It was set out in a November 1999 letter from the Coast Guard's boating safety chief at the time, and it capped new stock watercraft at 65 mph, with up to 2 mph more allowed for production variances. If speed is what makes you nervous, our guide to whether jet skis are dangerous covers the risks and the rules on our ride.

The same article says that agreement was voluntary, and that no official version was ever signed by every manufacturer. It also describes how the Coast Guard tested one supercharged model: two runs averaged, a standard 200-pound rider, full fuel. That test found the ski ran no better than 63 mph, even though magazine tests had reported it going faster.

Manufacturers today tend to sell on horsepower and handling. Sea-Doo's current RXP-X page, for example, leads with a 350 hp supercharged engine and race-inspired handling, and talks about carving buoys. The page we read lists no top speed in miles per hour.

There is also an engineering standard for measuring this. SAE International publishes a recommended practice called Maximum Velocity of Personal Watercraft (J2882), issued in its current form in September 2022, which sets a uniform test procedure for finding a personal watercraft's top speed.

Two people on the same model of ski, on the same morning, can come back with very different stories about how fast it felt. These are the things that make the difference.

Weight on the ski. The Coast Guard test in the background section used a standard 200-pound rider for a reason: load changes how a watercraft performs. On our skis the limits are fixed. A 1-seater carries one rider up to 250 lb. A 2-seater carries two riders up to 350 lb combined. A ski near its limit will feel heavier out of a turn than one carrying a single light rider.

One seat or two. On a 2-seater the driver is also carrying a passenger who has to hold on. Our FAQ says child passengers must be able to hold on independently. A good driver eases into speed with someone behind them.

The water. Flat water lets a ski run smoothly. Chop makes the hull bounce, and the same throttle feels faster and rougher. Kawasaki's owner's manual, as quoted on Wikipedia, tells riders to slow down before crossing waves and warns that high speed operation in choppy or rough water may cause back injuries.

Your eye level. You sit close to the water with spray coming off the hull and wind in your face. Speeds that feel calm in a car feel lively on a jet ski, which is why most riders find the open stretches plenty fast.

Traffic in the zone. Our FAQ explains that stopping to swim is not recommended during the ride because of the high traffic of other riders in the zone. More skis nearby means more spacing and more attention, and the guide sets the pace with that in mind.

These are typical groups that book the standard hour. The rules in each one come from our jet ski page, policies and FAQ; the feel of the ride is how the setup plays out on the water.

A couple sharing a 2-seater. One of you drives, the other rides behind. Your combined weight has to be 350 lb or less. The driver should expect a little more caution from the guide in the first minutes, because a passenger is aboard. Once you are steady, the open water is where you will feel the ski run. If both of you want to drive, book two 1-seaters instead, since you cannot swap mid-ride.

A parent and a 9-year-old. The parent drives a 2-seater (18 or older, photo ID) and the child rides passenger, which our pages allow from age 6, as long as the child can hold on independently. A parent or guardian signs the waiver for the minor. Plan on a smooth, steady pace. Hard bursts and sharp turns are harder on a small passenger holding the grab handles.

Three friends who all want speed. Each takes a 1-seater, each driver is 18 or older with ID, and anyone born after January 1, 1988 passes the short online state boating exam before the ride. Weight per rider is capped at 250 lb on a 1-seater. Expect the guide to watch spacing between your skis. Riders who stay predictable and keep their gaps get the most freedom on the throttle.

A solo first-timer. One 1-seater, ID, the exam if your birth date calls for it. Our FAQ says the guides give thorough instructions before your ride, even if it is your first time. Your first ten minutes will feel quick even at modest speed. That is normal, and it settles.

A family of four with two kids. Two 2-seaters, one parent driving each, one child as passenger on each. Both kids must be 6 or older and able to hold on. Check each pair against the 350 lb combined limit before you book.

Weather is the single biggest reason one ride feels faster and smoother than another. Our jet ski page is clear about where the line sits: light rain is normal and we ride; lightning, never.

On a rainy day the ride still goes, and the spray and drops on your face make even moderate speed feel quick. On a breezy afternoon the chop can make the guide hold the group to a gentler pace, for the reason Kawasaki gives in its manual: high speed in choppy or rough water can hurt your back. On a flat morning the water is at its most forgiving, and that is usually when riders feel the ski run cleanly.

Our policies say certified staff monitor the weather using radar apps and industry-standard judgment, and that the crew can reschedule based on weather. When conditions stop the ride, you get a credit voucher valid for 2 years, usable toward any activity we offer. Our jet ski page adds that you can reschedule to any future date or take that credit, with no fee.

Our post on how weather affects your Miami jet ski ride goes further into wind, rain and the bay.

At speed you get wet, and anything loose can end up in the bay. Pack light and pack for spray.

A few notes from our policies. There are no private changing rooms or lockers, so arrive dressed for the water. A group locker dock box is available for shoes and bags, though the crew is not responsible for lost, stolen or damaged items. Only cell phones may be brought on activities, and waterproof phone cases are for sale at check-in. The company is not responsible for lost or damaged phones, case or no case.

If you want to film your run, our post on capturing footage while jet skiing in Miami has ideas, and our jet ski rental requirements post lists every rule about ID, the exam and weight in one place.

To recap the speed question one last time: jet skis as machines are fast, and the 65 mph voluntary cap from 1999 is the number most often quoted as background. On our ride, the guide sets a safe and appropriate pace for the water and for you, inside a marked zone on Biscayne Bay. Our pages publish no top speed for our skis.

A few booking details from our pages. A refundable damage deposit is taken by card only, and it comes back unless there is a crash, damage or a policy violation; refunds can take up to 3 days for your bank to process. Fuel is included, and tax and the marina fee are added at check-in. For the current rate and what it includes, check the live price box on the booking page. If you want a second activity the same day, our combos pair the jet ski with parasailing, flyboard or the speed boat at the same marina, with one waiver and one parking spot.

Pick your ski, your date and your boarding window, and come ready to ride. Book a Miami jet ski rental at Dinner Key Marina and feel the speed for yourself.
