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, a personal flotation device. In addition, the skier must have adequate upper and lower body strength, muscular endurance, good balance. There are water ski participants around the world, in Asia and Australia, Europe and the Americas. In the United States alone, there are 11 million water skiers and over 900 sanctioned water ski competitions every year. Australia boasts 1.3 million water skiers. There are many options for competitive water skiers; these include speed skiing, trick skiing, show skiing, jumping, barefoot skiing and wakeski. Similar, related sports are wakeboarding, discing and sit-down hydrofoil. Water skiers can start their ski set in one of two ways: wet is the most common, but dry is possible.

Water skiing 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, put them on while in the water. Most times it can be easier to put the skis on. 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; the skier can perform a "dry start" by standing on the shore or a pier. When the skier is ready, the driver accelerates the boat; as the boat accelerates and takes up the slack on the rope, the skier allows the boat to pull them out of the water by applying some muscle strength to get them! into an upright body position. By leaning back and keeping the legs bent, the skis will plane out and the skier will start to glide over the water; the skier turns by shifting weight right. The skier's body weight should be balanced between the balls of the heels.

While being towed, the skier's arms should be relaxed but still 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 inform the driver if the skier falls. The spotter sits in a chair on the boat facing backwards to see the skier; the skier and the boat's occupants communicate using hand signals. 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 skiing space and the water should be at least 1.5 to 1.8 metres deep. There must be enough space for the water skier to safely "get up", or be in the upright skiing position. Skiers and their boat drivers must have sufficient room to avoid hazards. Younger skiers start out on children's skis, which consist of two skis tied together at their back and front.

These connections mean. Sometimes these skis can come with a handle to help balance the skier as well. Children's skis are short – 110–150 centimetres long – 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 one ski; the heavier the person, the bigger the skis will be. Length will vary based on the type of water skiing being performed. A trick ski is around 40 inches long and wider than combo skis. Again the skier rides it with her dominant foot in front, it has no fins. Competition skiing uses designed towboats. Most towboats have a 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, 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, Centurion Carbon Pro.

These boats have ability to pull skiers for trick skiing and slalom. Recreational boats can serve as water skiing platforms as well as other purposes such as cruising and fishing. Popular boat types include bowriders, cuddy cabins, jetboats; the towboat must be capable of maintaining the proper speed. Speeds vary with the skier's weight, experience level, comfort level, type of skiing. For example, a child on two skis would require speeds of 21–26 km/h, whereas an adult on one ski might require as high as 58 km/h. Barefoot skiing requires speeds of 72 km/h. Competition spee
