Water skiing also waterskiing or 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 , Used Small Center Console Boats For Sale With 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, two or three people depending on local boating laws , [1] and a personal flotation device.
In addition, the skier must have adequate upper and lower body strength, muscular endurance, and good balance. There are water ski participants around the world, in Asia and Australia , Europe , Africa , and the Americas. There are many options for recreational or competitive water skiers. These include speed skiing, trick skiing, show skiing, slaloming, jumping, barefoot skiing and wakeski. Similar, related sports are wakeboarding , kneeboarding , [5] discing , tubing , 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 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.
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 them out of the water by applying some muscle strength to get 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 metre-wide ft skiing space and the water should be at least 1. 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. 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. 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" [7] or one ski dominant foot in front of the other foot, [8] also called "slalom skiing" [7]. 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 long 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.
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. 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. 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 [14] within tolerance [15] 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 [16] to the flexibility as long as the same specification is used "for the entire event. This anchor point on a recreation boat is commonly a tow ring or cleat, mounted on the boat's stern. This pylon must be mounted securely, since a skilled slalom skier can put a considerable amount of tension on the ski rope and the pylon.
There should be a feet 61 m wide skiing space and the water should be at least 5 to 6 feet 1. The towboat should stay at least feet 30 m from docks, swim areas, and the shore, and other boats should steer clear of skiers by at least feet 30 m.
Another common cause of injury is colliding with objects on or near the water, like docks. The tow boat must contain at least two people: a driver and an observer. 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.
Water skiing was invented in when Ralph Samuelson used a pair of boards as skis and a clothesline as a towrope on Lake Pepin in Lake City, Minnesota. 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. Samuelson went through several iterations of equipment in his quest to ski on water.
His first equipment consisted of barrel staves for skis. The ski rope was made from a long window sash cord. The first patent for water skis was issued to Fred Waller , of Huntington, NY, on 27 October , for skis he developed independently and marketed as "Dolphin Akwa-Skees.
Jack Andresen patented the first trick ski, a shorter, fin-less water ski, in In , Don Ibsen developed his own water skis out in Bellevue, Washington, never having heard of Samuelson or Waller. 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. The sport of water skiing remained an obscure activity for several years after , until Samuelson performed water ski shows from Michigan to Florida.
The American Water Ski Association formally acknowledged Samuelson in 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.
A demonstrating behind a motorboat was made to the Swedish public at the th anniversary of the Royal Swedish Yacht Club in Sandhamn outside Stockholm in Water skiing gained international attention in the hands of famed promoter, Dick Pope, Sr.
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 s and s, helping to bring international attention to the sport for the first time. 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 Olympics. Its first inclusion in tournament slalom skiing was in In the United States, there are over sanctioned water ski competitions each summer. 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 � 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 Small Boats Perth Usa 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. The drivers boat path must be verified as well to ensure that all skiers are getting a fair pull. Every consecutive [31] 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 Small Boats With Sails Journal shortens until the skier fails to complete the slalom course by falling or not getting around a buoy. 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 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.
