Third pass of the morning, rope shortened, boat at full speed. The skier leans into the 4 ball, the tip catches, and she cartwheels across the course. The safety boat is there in seconds, a hand goes up, and the dock exhales. Water skiing mixes speed, a rope, a boat and an engine, and a handful of injuries keep showing up in the research. Here they are, with what lowers the risk and when to get help, for every level: kids on combo skis, weekend crews, college teams, tournament, show and barefoot skiers.

General information, not medical advice. If you’re hurt, see a sports medicine doctor, physical therapist (PT) or certified athletic trainer (AT); in an emergency, call 911. For the big picture, start at our water skiing hub.

What the research shows

A study of US emergency departments from 2001 to 2003 estimated about 23,000 water skiing injuries treated in those three years. Sprains and strains were the most common type (36%), and more than half of those were in the legs. Head injuries were only about 4%, far fewer than in wakeboarding. A newer review of that database (2012 to 2022, 898 cases) listed the head (20%), face (10%) and knee (8%) as the most common injured areas, and its authors called for more protective gear, especially headgear.

Competitive skiers show a similar pattern. Among 96 college water skiers surveyed at US tournaments, the ankle and foot (27%), knee (17%) and head and neck (16%) were the most injured areas, and twisting (33%) and sudden stops (27%) were the most common causes.

Knees and ankles

Your feet are locked into bindings and the ski can stop dead when a tip catches, so the knee and ankle take the twist. The American Academy of Orthopaedic Surgeons (AAOS) lists the classic signs of an ACL (anterior cruciate ligament) tear: a pop, the knee giving way, and swelling within 24 hours. A suspected ACL tear always needs a doctor. For ankles, the National Athletic Trainers’ Association (NATA) says the most consistent risk factor for a sprain is a previous sprain, and recommends at least three months of balance training after one.

• Bindings that fit and release. Check them before every session; a torn or loose binding is a reason to stop, not to “make it work”.
• Build strength and balance on land. In team sports, programs with strength, landing and balance work cut ACL injuries by about half in a large review; our training page adapts them for skiers.
• Stop when your legs are cooked. Advanced college skiers were hurt mostly by losing control, and tired legs lose control.

After a knee injury, some skiers like a supportive sleeve such as the Bauerfeind GenuTrain for comfort in land training; it doesn’t replace rehab with a PT. See our best knee sleeves guide.

Hamstrings: the water skier’s pull

AAOS names water skiing among the sports where hamstring injuries are common. The hamstring is stretched hardest when the hip bends deeply with the knee straight, which is the position a skier ends up in when a ski shoots forward during a start or the body folds over the skis in a fall. In the most severe cases the tendon tears completely off the bone (an avulsion), sometimes taking a piece of bone with it. Warning signs: sudden sharp pain in the back of the thigh or buttock, swelling, bruising down the back of the leg over the next days, and weakness. Sports medicine surgeons list a complete tear of the hamstring at the hip among the injuries that need prompt treatment, so a big pop plus bruising and weakness means seeing a doctor within days, not “waiting to see”.

The back and the jump

Jumpers hit a ramp at speed and land far down the course. A British review of tournament skiing found that high-speed impacts cause most slalom and jump trauma, and “a surprisingly high incidence” of lower-back injuries in the jump event. Its authors suggest the spine may be damaged by overuse, especially before the skeleton is mature, which matters for young jumpers. Low-back pain is common even without a crash: 43% of the college skiers in the US survey reported chronic trunk pain, and the researchers recommended a systematic core-strength program. Build up jump speed and distance with a coach, and get back pain with leg numbness, or pain that lasts, checked.

Shoulders, arms and the rope

A deep-water start loads the arms with roughly one and a half times body weight, according to a study that measured takeoff forces in water skiers. Slalom turns load them again on every buoy. Case reports describe tears of the large back and shoulder muscles (latissimus dorsi and teres major) in water skiers, and shoulders can dislocate in falls when the handle yanks an arm overhead.

• Let go when a fall starts. Hanging on is how arms get pulled overhead.
• Never wrap the rope around a hand, wrist or arm, and keep it away from legs in the water. A loose rope coiling around a body part and then pulling tight can cause serious injury.
• Ease into the start: knees bent, arms straight; let the boat pull you up.

Head injuries and concussion

Water feels hard at 30-plus miles per hour, and so do skis and ramps. USA Water Ski & Wake Sports tournament rules make protective headgear mandatory in the jump event, and many recreational skiers now wear a water sports helmet too.

Concussion: recognize it and sit out. The CDC’s HEADS UP program says to remove anyone who may have a concussion from activity: “When in doubt, sit them out”, for the rest of the day and until a health care provider clears them. Signs include looking dazed, confusion, slow answers, clumsiness and mood changes; skiers may report headache, dizziness, nausea, blurry vision or feeling foggy. Call 911 for the danger signs: one pupil larger than the other, a headache that gets worse, slurred speech, weakness or numbness, repeated vomiting, seizures, growing confusion or drowsiness, or loss of consciousness.

Rare but serious: water-force injuries. Doctors have reported internal injuries, including serious vaginal tears with heavy bleeding, when water is forced into the body in a high-speed fall. They’re uncommon, but any bleeding or severe belly or pelvic pain after a fall needs urgent care.

Propellers and the boat

The most serious injuries in towed sports usually involve the boat. The US Coast Guard counted 169 incidents in 2024 in which at least one person was struck by a propeller, with 30 deaths and 158 injuries; towed water sports overall accounted for 19 deaths and 242 injuries that year. The Coast Guard’s advice: shut off the engine when you approach people in the water, keep them on the driver’s side and in view. On boats under 26 feet, federal law requires the driver to use the engine cut-off switch lanyard while on plane. Tournament rules forbid picking up a ski, skier or rope with the ignition on.

• Engine off, not just neutral, near a skier. California’s boating agency notes a propeller may still turn in neutral, and says never to back the boat up to a skier.
• Have a spotter whose only job is to watch the skier. Some states require one; California, for example, requires an observer at least 12 years old.
• After a fall, be seen. Signal you’re OK and hold a ski up so other boats see you. Our rules and safety page has the hand signals and flag rules.

Carbon monoxide at the back of the boat

Boat engines make carbon monoxide (CO), a gas you can’t see, smell or taste. The Coast Guard warns it can build up around the stern and swim platform at slow speeds, while idling and even after the engine stops, and that early symptoms (irritated eyes, headache, nausea, weakness, dizziness) are easily mistaken for seasickness. Engine off while skiers get on and off, nobody on the swim platform with the engine running, and treat “seasick” as possible CO: fresh air and medical help.

Drowning and life jackets

In 2024, 76% of the people who died in US recreational boating drowned where the cause was known, and 87% of those who drowned weren’t wearing a life jacket. The CDC says life jackets reduce the risk of drowning while boating for people of all ages and swimming abilities.

• Coast Guard approved, made for towed sports. Check the label: the Coast Guard notes some life jackets are not approved for water skiing.
• No inflatables, no ski belts. Inflatable jackets aren’t approved for towed sports in states such as California, and California’s boating agency notes ski belts are not Coast Guard approved. Tournament rules require non-inflatable flotation and say a life belt doesn’t protect the ribs and organs enough.
• Tournament skiers: USA Water Ski & Wake Sports requires a Coast Guard approved Type III vest in slalom and jump, or, at the skier’s own risk, a maker’s competition vest that floats the skier. State law still applies on the lake.
• No alcohol for driver, spotter or skier. It was the leading known factor in fatal boating incidents in the Coast Guard’s 2024 report, and tournament rules bar anyone under the influence.

Water, cold and sun

• Warm freshwater and your nose. Falls force lake water up the nose. Infections from the ameba Naegleria fowleri are rare (fewer than 10 US deaths a year, per the CDC), but the CDC suggests avoiding warm, low water and holding your nose or using a nose clip when you go in.
• Cold water. The Coast Guard describes cold shock in the first minute and loss of muscle control within about 10 minutes; dress for the water, not the air.
• Sun and heat are on our Tournament Day page.

When to get help

• Call 911 now: an unconscious or confused skier, concussion danger signs, a propeller injury or heavy bleeding, trouble breathing after being under water, a suspected neck or back injury (California’s boating agency advises getting in the water to support an injured skier rather than hauling them aboard), or possible CO poisoning.
• See a doctor soon: a knee that popped, gave way or swelled; a hamstring “pop” with bruising and weakness; an ankle you can’t walk on; a shoulder that slipped out; back pain with leg numbness; any suspected concussion.
• See a PT or athletic trainer: pain that keeps coming back, a joint that feels unstable, or a plan to return after an injury.

Next: build the legs, back and grip that protect you on the training page, and get your body back after a big day on the recovery page. Kids: see our youth page. Riding a board instead? See wakeboarding injuries.

Water skiing injuries: FAQs

What is the most common water skiing injury?

Sprains and strains, mostly in the legs, were the most common water skiing injuries in US emergency departments. Among college tournament skiers, the ankle and foot, knee, and head and neck were the most injured areas, usually from twisting or sudden stops.

Why do water skiers tear their hamstrings?

Starts and falls can bend the hip deeply while the knee is straight, which stretches the hamstring hard. AAOS lists water skiing among the sports where hamstring injuries are common. A sudden pop with bruising and weakness needs a doctor soon, because complete tears at the hip are treated best early.

Do I need a helmet for water skiing?

For jumping, yes: USA Water Ski & Wake Sports tournament rules make protective headgear mandatory in the jump event. For slalom and recreational skiing it’s a personal choice, but head and face are among the most common injured areas in national data, and the authors of a recent study recommend headgear.

Can I water ski with an inflatable life jacket or a ski belt?

No. Inflatable life jackets aren’t approved for towed sports in states such as California, ski belts are not Coast Guard approved, and tournament rules call for non-inflatable flotation. Wear a foam, Coast Guard approved vest that fits snugly.
