Water skiing is a surface water sport in which an individual is pulled behind a boat or a cable ski installation over a body of water, skimming the surface on two skis or one ski. The sport requires sufficient area on a smooth stretch of water, one or two skis, a tow boat with tow rope, three people (depending on state boating laws), and a personal flotation device. In addition, the skier must have adequate upper and lower body strength, muscular endurance, and good balance. Skiing is a fun pastime that allows people of all skill levels and ages to enjoy. There is no minimum age necessary to water ski.

There are water ski participants around the world, in Asia and Australia, Europe, Africa, and the Americas.[1] In the United States alone, there are approximately 11 million water skiers and over 900 sanctioned water ski competitions every year.[2] Australia boasts 1.3 million water skiers.[3]

There are many options for recreational or competitive water skiers. These include speed skiing, trick skiing, show skiing, slaloming, jumping, and barefoot skiing. Similar, related sports are wakeboarding, kneeboarding,[4] discing, tubing, and sit-down hydrofoil.

Water skiers rising out of the water

Water skiers can start their ski set in one of two ways: wet is the most common, but dry is possible. Water skiing typically begins with a deep water start. The skier enters the water with their skis on or they jump in without the skis on their feet, have the skis floated to them, and put them on while in the water. Most times it can be easier to put the skis on when they are wet. Once the skier has their skis on they will be thrown a tow rope from the boat, which they position between their skis. In the deep water start, the skier crouches down in the water while holding onto the ski rope; they are in a cannonball position with their legs tucked into their chest, with skis pointing towards the sky and approximately 30 cm (0.98 ft) of the ski out of the water. The skier can also perform a "dry start" by standing on the shore or a pier; however, this type of entry is recommended for professionals only. When the skier is ready (usually acknowledged by them yelling "hit it"), the driver accelerates the boat. As the boat accelerates and takes up the slack on the rope, the skier allows the boat to pull him/her out of the water by applying some muscle strength to get him/her into an upright body position.

By leaning back and keeping the legs slightly bent, the skis will eventually plane out and the skier will start to glide over the water. The skier turns by shifting weight left or right. The skier's body weight should be balanced between the balls of the feet and the heels. While being towed, the skier's arms should be relaxed but still fully extended so as to reduce stress on the arms. The handle can be held vertically or horizontally, depending on whichever position is more comfortable for the skier.

In addition to the driver and the skier, a third person known as the spotter or the observer should be present. The spotter's job is to watch the skier and inform the driver if the skier falls. The spotter usually sits in a chair on the boat facing backwards to see the skier. The skier and the boat's occupants communicate using hand signals (see the Safety section below).

Water skiing can take place on any type of water – such as a river, lake, or ocean – but calmer waters are ideal for recreational skiing. There should be a 60-metre-wide (200 ft) skiing space and the water should be at least 1.5 to 1.8 metres (5 to 6 ft) deep. There must be enough space for the water skier to safely "get up," or successfully be in the upright skiing position. Skiers and their boat drivers must also have sufficient room to avoid hazards.

Several types of water skis and wetsuits

Younger skiers generally start out on children's skis, which consist of two skis tied together at their back and front. These connections mean that less strength is necessary for the child to keep the skis together. Sometimes these skis can come with a handle to help balance the skier as well.[5] Children's skis are short – usually 110–150 centimetres (45–60 in) long[5] – reflecting the skier's smaller size. Once a person is strong enough to hold the skis together themselves there are various options depending upon their skill level and weight.

Water skiers can use two skis (one on each foot, also called "combo skiing"[6]) or one ski (dominant foot in front of the other foot,[7] also called "slalom skiing"[6]). Generally the heavier the person, the bigger the skis will be. Length will also vary based on the type of water skiing being performed; jump skis, for example, are longer than skis used in regular straight-line recreational skiing or competitive slalom and trick skiing. A trick ski is around 40 inches and wider than combo skis. Again the skier rides it with his or her dominant foot in front. It has no fins which allows for spins to be performed.


Competition skiing uses specifically designed towboats. Most towboats have a very small hull and a flat bottom to minimize wake. A true tournament ski boat will have a direct drive motor shaft that centers the weight in the boat for an optimal wake shape. However, some recreational ski boats will have the motor placed in the back of the boat (v-drive), which creates a bigger wake. Permitted towboats used for tournament water skiing are the Mastercraft ProStar 197, MasterCraft ProStar 190, Nautique 200, Malibu Response TXi, and Centurion Carbon Pro.[8] These boats have ability to pull skiers for trick skiing, jumping, and slalom.[9]

Recreational boats can serve as water skiing platforms as well as other purposes such as cruising and fishing. Popular boat types include bowriders, deckboats, cuddy cabins, and jetboats.[10]

The towboat must be capable of maintaining the proper speed. Speeds vary with the skier's weight, experience level, comfort level, and type of skiing.[11] For example, a child on two skis would require speeds of 21–26 km/h (13–16 mph), whereas an adult on one ski might require as high as 58 km/h (36 mph). Barefoot skiing requires speeds of approximately 72 km/h (45 mph; 39 kn). Competition speeds have a wide range: as slow as 22 km/h (14 mph; 12 kn) up to 58 km/h (36 mph; 31 kn) for slalom water skiing, and approaching 190 km/h (120 mph; 100 kn) in water ski racing.[12]

The boat must be equipped with a ski rope and handle. The tow rope must be sufficiently long for maneuvering, with a recommended length of 23 metres (75 ft)[13] (within tolerance[14]) although length varies widely depending on the type of water skiing and the skier's skill level. Competition requirements on rope construction have changed over the years, from "quarter-inch polypropylene rope" in 1992[15] to the 2003 flexibility as long as the same specification is used "for the entire event."[16] The rope and handle are anchored to the boat and played out at the stern. This anchor point on a recreation boat is commonly a tow ring or cleat, mounted on the boat's stern.[citation needed] For more dedicated skiers, a metal ski pylon is placed in the center of the boat in front of the engine to connect the skier. This pylon is mounted securely, since a skilled slalom skier can put a considerable amount of tension in the ski rope and the pylon.

Safety measures[]

As water skiing is a potentially dangerous sport, safety is important.

There should be a 200 feet (61 m) wide skiing space and the water should be at least 5 to 6 feet (1.5 to 1.8 m) deep. The towboat should stay at least 100 feet (30 m) from docks, swim areas, and the shore, and other boats should steer clear of skiers by at least 100 feet (30 m).[13] Without proper space and visibility skiing can be extremely dangerous.

The skier should know how to swim, but he or she should wear a life jacket regardless of swimming ability.[11] Specially-designed life jackets or ski vests allow movement needed for the sport while still providing floation for a downed or injured skier.[17] The most common water ski injuries involve the lower legs, such as the knee, because a fall at high speed can create irregular angles of collision between the skier's body and the water surface. Another common cause of injury is colliding with objects on or near the water, like docks.[11]

The tow boat must contain at least two people.[11] The driver maintains a steady course, free of obstacles to the skier. The observer continually observes the skier, relays the condition of the skier to the boat driver, and if necessary, raises the "skier down" warning flag, as required, when a skier is in the water, returning to the boat, or in some localities, the entire time the skier is out of the boat.[18][19] The skier and observer should agree on a set of standard hand-signals for easy communication: stop, speed up, turn, I'm OK, skier in the water, etc.[11][20]



A water skier on one ski (slalom style)

Water skiing was invented in 1922 when Ralph Samuelson used a pair of boards as skis and a clothesline as a towrope on Lake Pepin in Lake City, Minnesota. Samuelson experimented with different positions on the skis for several days until 2 July 1922. Samuelson discovered that leaning backwards in the water with ski tips up and poking out of the water at the tip was the optimal method. His brother Ben towed him and they reached a speed of 32 kilometres per hour (20 mph).[21] Samuelson spent 15 years performing shows and teaching water skiing to people in the United States.

Samuelson went through several iterations of equipment in his quest to ski on water. His first equipment consisted of barrel staves for skis.[21] He later tried snow skis,[21] but finally fabricated his own design out of lumber with bindings made of strips of leather. The ski rope was made from a long window sash cord.[21] Samuelson never patented any of his ski equipment.

The first patent for water skis was issued to Fred Waller, of Huntington, NY, on 27 October 1925, for skis he developed independently and marketed as "Dolphin Akwa-Skees." Waller's skis were constructed of kiln-dried mahogany, as were some boats at that time. Jack Andresen patented the first trick ski, a shorter, fin-less water ski, in 1940.

In 1928 Don Ibsen developed his own water skis on the West Coast, never having heard of Samuelson or Waller. In 1941 Don Ibsen founded The Olympic Water Ski Club in Seattle, WA. It was the first such club in America. Ibsen, a showman and entrepreneur, was one of the earliest manufacturers of water skis and was a leading enthusiast and promoter of the sport. In 1983 he was inducted into the Water Ski Hall of Fame in Winterhaven, FL.

The sport of water skiing remained an obscure activity for several years after 1922, until Samuelson performed water ski shows from Michigan to Florida. The American Water Ski Association formally acknowledged Samuelson in 1966 as the first recorded water skier in history. Samuelson was also the first ski racer, slalom skier, and the first organizer of a water ski show.[22]

Water skiing gained international attention in the hands of famed promoter, Dick Pope, Sr., often referred to as the "Father of American Water Skiing" and founder of Cypress Gardens in Winter Haven, Florida. Pope cultivated a distinct image for his theme-park, which included countless photographs of the water skiers featured at the park. These photographs began appearing in magazines worldwide in the 1940s and 1950s, helping to bring international attention to the sport for the first time.[23] He was also the first person to complete a jump on water skis, jumping over a wooden ramp in 1928, for a distance of 25 feet.[24] His son, Dick Pope, Jr., is the inventor of bare-foot skiing. Both men are in the Water Ski Hall of Fame. Today, Winter Haven, Florida, with its famous Chain of Lakes, remains an important city for water skiing, with several major ski schools operating there.

Water skiing has developed over time. Water skiing tournaments and water skiing competitions have been organized. As an exhibition sport, water skiing was included in the 1972 Olympics. The first National Show Ski Tournament was held in 1974, and the first ever National Intercollegiate Water Ski Championships were held in 1979. The Home CARE US National Water Ski Challenge, the first competition for people with disabilities, was organized ten years later.

The first patented design of a water ski which included carbon fiber was that of Hani Audah at SPORT labs in 2001. Its first inclusion in tournament slalom skiing was in 2003.[25]


3-event tournament water skiing[]

In the United States, there are over 900 sanctioned water ski competitions each summer.[2] Competitive water skiing consists of three events: slalom, jump, and trick.[2][26]


File:Slalom Good Pic.jpg

In an attempt to become as agile as possible, slalom water skiers use only one ski with feet oriented forward, one in front of the other. Slalom skis are narrow and long, at 57–70 inches (145–178 cm) depending on the height and weight of the skier. The two forward-facing bindings vary: they can be made of rubber or thick plastic, and they can be designed more like a snow ski binding or more like a roller blade boot.

Slalom skiing involves a multi-buoy course that the skier must go around in order to complete the pass. A complete slalom water ski course consists of 26 buoys. There are entrance gates at the beginning and end of the course that the skier must go between, and there are 6 turn buoys that the skier must navigate around in a zigzag pattern. The remainder of the buoys are for the driver to ensure the boat goes straight down the center of the course. For a tournament to be sanctioned as 'record capable' by the International Waterski & Wakeboard Federation (IWWF), the entire course must be surveyed prior to competition by a land surveyor to ensure its accuracy. The drivers boat path must be verified as well to ensure that all skiers are getting a fair pull.

Every consecutive[26] pass is harder than the pass before it. When a pass is completed, the boat is sped up by 3 kilometres per hour (2 mph) until the maximum speed has been reached for the division, based on the skier's gender and age (55 kilometres per hour (34 mph) for women and 58 kilometres per hour (36 mph) for men). After the skier has run their maximum speed pass, the rope is shortened at specific increments to make it more difficult to reach the buoy width. In a tournament, the boat speeds up or the rope shortens until the skier fails to complete the slalom course by falling or not getting around a buoy.[26]

A skier's score is based upon the number of successful buoys cleared, the speed of the boat, and the length of the rope. In a tournament, skiers choose the starting boat speed and rope length (with a maximum length of 22.86 metres (75 ft)). Professional water skiers will typically start at the max speed of 58 kilometres per hour (36 mph) with a rope that has already been shortened to 13 metres (43 ft). The skier with the most buoys wins the competition.[26]

The turn buoys are positioned 11.5 metres (38 ft) away from the center of the slalom course so as the rope is shortened beyond that the skiers are required to use the momentum generated through their turns to swing up on the side of the boat and reach out in order to get their ski around the next buoy. At this rope length the skier's body is experiencing intense isometric contractions and extreme upper body torque with loads of up to 600 kg as they begin accelerating after rounding a turn buoy. Their top speeds will generally be more than double the boat's speed, which means that the Pro men can reach speeds in excess of 116 kilometres per hour (72 mph) and each turn will generally generate around 4 g of force. Essentially, slalom water skiers are using their body as a lever, which allows them to withstand loads that would otherwise not be possible for the human body.

Water ski jumpers use two long skis to ride over a water ski jump in an attempt to travel the longest distance. In a tournament, skiers are given three attempts to hit the ramp. The winner is the skier who travels the farthest calculated[16] distance and successfully rides away.[27] There are no style points, simply distance.[26]

Water ski jumps have specific dimensions and the ramp height is adjustable. Skiers may choose their boat speed and ramp height, although there are maximums based the skier's gender and age. Professional ski jumpers have a maximum boat speed of 58 km/h (36 mph; 31 kn). The ramp height must be between 1.5 and 1.8 m (5 and 6 ft). As a professional jumper approaches the ramp they will zigzag behind the boat in a series of cuts[27] to generate speed and angle. When the jumper hits the ramp they will generally be going over 112 kilometres per hour (70 mph) and the load they have generated on the rope can be over 600 kilograms (1,300 lb).

The Trick competition has been described as the most technical of the three classic water skiing events.[26]

Trick skiing uses small, oval-shaped water skis. Beginners generally use two skis while more advanced skiers use one.[26] The shorter, wider Trick ski has a front binding facing forward and a back binding facing at a 45°. It has a smooth bottom that allows it to turn over the surface of the water. According to official 2013 Tournament Rules for 3-event competition in the United States and the Pan-Am Games, skis used in the Tricks event must be a single ski without fins, although molded rails/grooves less than 6.4 mm (14 in) are allowed, as are a foot pad cemented to the ski as a place for the rear foot; in addition, the ski must float with all bindings, fins, etc., installed.[citation needed] The ski's configuration allows the skier to perform both surface and air tricks in quick succession.

In a tournament, skiers are given two 20-second runs during which they perform a series of their chosen tricks. One pass is for hand tricks, which includes surface turns, rotations over the wake, and flips. The second pass is for toe tricks, which are done by doing wake turns and rotations with only a foot attaching them to the handle; the foot is either in the toehold part of the handle or, professionally, attached to the rope.[26] A trick cannot be repeated.[26] Each trick has a point value. A panel of five judges assesses which tricks were completed correctly and assigns that predetermined point value to each successfully completed trick. The skier with the most points wins.[26]

Barefoot water skiing[]

Barefoot skiing on Lake Ozonia in the Adirondacks

Main article: Barefoot skiing

A barefoot water skier should use a wetsuit instead of a life jacket because the wetsuit covers more of the body in case of a fall at high speed. The wetsuit also allows the skier to do starts in the water where they lie on their back. Unlike a normal life jacket, the "barefoot wetsuit" allows the skier to glide on their back on top of the water once they reach a high enough speed. The barefoot wetsuit is generally thicker in the back, rear, and chest for flotation and impact absorption.

Barefoot skiing requires a higher speed because the skier's feet are smaller than skis, providing less lift. A rule of thumb for barefoot water skiing speed in miles per hour is (M/10)+18=S, where M equals the skier's weight in pounds. In other words, a 175 lb (79 kg) person would have to divide 175/10, which is 17.5; then simply add 17.5+18 which equals 35.5 miles per hour (57.1 km/h).

Another tool used in barefoot water skiing is the barefoot boom. It provides a stable aluminum bar on the side of the boat where a short rope can be attached or the skier can grip the bar itself. The skier is within earshot of the people in the boat, providing a good platform for teaching. Once the bare footer is good enough, he/she will go behind the boat with a long rope.

A beginner can wear shoes to decrease the necessary speed, lessen foot injury from choppy water, learn better technique, and master the sport.

Show skiing[]

Show skiing is a type of water skiing where skiers perform tricks somewhat similar to those of gymnasts while being pulled by the boat. Traditional ski show acts include pyramids, ski doubles, freestyle jumping, and swivel skiing. Show skiing is normally performed in water ski shows, with elaborate costumes, choreography, music, and an announcer. Show teams may also compete regionally or nationally. In the USA, each team member must be a member of USA Water Ski to compete.

The first organized show occurred in 1928.[28] The bi-annual World Show Ski Championship was inaugurated in September 2012 in Janesville, Wisconsin.[29][30] Past competition included teams from Australia, Belgium, Canada, China, and the United States.[29]

Freestyle jumping[]

Freestyle jumping is often related to show skiing. The goal is to go off the jump, perform one of many stunts, and successfully land back on the water. The most common freestyle stunts – in order of usual progression – would be a heli (360°), a flip (forwards), a gainer (a back flip), and a möbius (back flip with 360°).

Ski racing in Australia

Ski racing[]

Water ski racing consists of a number of water skiers who race around a set course.

A team consists of a boat driver, an observer, and one to two skiers depending on the race. The driver tows the skier behind a powerboat, varying the speed based on conditions, his or her knowledge of the skier, the observer's ability to read the skier, and the skier's signals.


The marathon event consists of each skier having to ski on all 6 pieces of equipment – Single ski, Double skis, Single, Single finless, Double finless, a freeboard (a ski without bindings), and a fence paling.

World records[]

The most skiers towed behind one boat is 145, set by the Horsehead Water Ski Club in Strahan, Tasmania, Australia, on 27 January 2012. Previously the record had stood at 100 skiers for 24 years before a huge team led by Horsehead broke the record in 2010 with 114 skiers. The skiers used 8 kilometres (5.0 mi) of ski rope and were towed by the 36 m 2,200 kW (3,000 hp) World Heritage Cruises' catamaran Eagle.[31]

On 31 August 1974, David Scott Munro of the Ross-shire Caberfeidh Water Ski Club became the first person to water ski (mono ski) the length of Loch Ness, Scotland. From Lochend to Fort Augustus and back, he covered the 77 km (48 mi) in 77 minutes at an average speed of 60 km/h (37 mph).[32]

The world record (approved) in slalom is 2.5 buoys at 9.75 m or 32 ft (43 ft off) which was set by Nate Smith in September 2013.[33]

World records in ski jump have been tracked since the first World Championships, in 1949.[34] The current world record is held by Freddy Krueger; it was set in 2015 at a distance of 312 ft (95 m).[35]
