Rafting or whitewater rafting is a challenging recreational activity utilizing a
raftto navigate a riveror other bodies of water. This is usually done on whitewateror different degrees of rough water, in order to thrill and excite the raft passengers. The development of this activity as a leisure sport has become popular since the mid 1970s.
Rafting is one of the earliest means of transportation, used as a means for shipping people, hunting, and transferring food.
In 1842, Lieutenant John Fremont of the U.S. Army first journalized his rafting expedition on the
Platte River. Horace H. Day designed the equipment he used in rafting. Day’s rafts were constructed from four independent rubber cloth tubes and wrap-around floor. [ [http://www.abc-of-rafting.com/info/rafting-history.asp History of Rafting] ]
In 1960s, rafting was then recognized and paths like
Grand Canyonwere routed and whitewater rafting companies were established.
In 1970s, rafting marked its major development as a leisure sport when it was then included in the Munich Olympic Games.
In 1980s, as rafting continued to gain its popularity, many rivers were opened for rafting activities including rivers in South America and Africa.
In 1990s, rafting was included in major game events like the Barcelona Games in 1992, Atlanta Games in 1996, and the whitewater events of the Summer Olympic Games hosted by Ocoee River in Tennessee Valley. In addition, the International Federation of Rafting was instituted in 1997 and in 1999 the first Official International Championship was held.
Currently, river rafting is still gaining popularity among extreme water sports in order to thrill and excite the raft passengers.Fact|date=June 2007
Rafts were originally the simplest form of man’s transportation in water and were then made of several logs, planks or reeds which were fastened together. Nowadays,
inflatable boatwere used as rafts which were later adopted by the military for beach assaults. It consists of very durable, multi-layered rubberized or vinyl fabrics with several independent air chambers. Its length varies between 3.5 m (11 ft) and 6 m (20 ft), the width between 1.8 m (6 ft) and 2.5 m (8 ft). The exception to this size rule is usually the packraft, which is designed as a portable single-person raft and may be as small as 1.5m long and weigh as little as 4 lbs.
Rafts come in a few different forms. In Europe the most common is the symmetrical raft steered with a paddle at the stern. Other types are the asymmetrical, rudder-controlled raft and the symmetrical raft with central helm (
oars). Rafts are usually propelled with ordinary paddles and typically hold 4 to 12 persons. In Russia rafts are often hand made and are often a catamaran style with two inflatable tubes attached to a frame. Pairs of paddlers navigate these rafts. Catamaranstyle rafts have become popular in the western United States as well, but are typically rowed instead of paddled.
Rivers with high current are used for White water rafting. Specially, White Water Rafting is popular in
Nepaldue to high current of water falling through hills and rocky mountains.
Classes of Whitewater
Class 1: Very small rough areas, requires no maneuvering. (Skill Level: None)
Class 2: Some rough water, maybe some rocks, might require maneuvering.(Skill Level: Basic Paddling Skill)
Class 3: Whitewater, small waves, maybe a small drop, but no considerable danger. May require significant maneuvering.(Skill Level: Experienced paddling skills)
Class 4: Whitewater, medium waves, maybe rocks, maybe a considerable drop, sharp maneuvers may be needed. (Skill Level: Whitewater Experience)
Class 5: Whitewater, large waves, possibility of large rocks and hazards, possibility of a large drop, requires precise maneuvering (Skill Level: Advanced Whitewater Experience)
Class 6: Class 6 rapids are considered to be so dangerous as to be effectively unnavigable on a reliably safe basis. Rafters can expect to encounter substantial whitewater, huge waves, huge rocks and hazards, and/or substantial drops that will impart severe impacts beyond the structural capacities and impact ratings of most all rafting equipment. Traversing a Class 6 rapid has a dramatically increased likelihood of ending in serious injury or death compared to lesser classes. (Skill Level: Successful completion of a Class 6 rapid without serious injury or death is widely considered to be a matter of luck or extreme skill)
Whitewater rafting can be a dangerous sport, especially if basic safety precautions are not observed. Both commercial and private trips have seen their share of injuries and fatalities, though private travel has typically been associated with greater risk. Depending on the area, legislated safety measures may exist for rafting operators. These range from certification of outfitters, rafts, and raft leaders, to more stringent regulations about equipment and procedures. It is generally advisable to discuss safety measures with a rafting operator before signing on for a trip. The equipment used and the qualifications of the company and raft guides are essential information to be considered.
Like most outdoor sports, rafting in general has become safer over the years. Expertise in the sport has increased, and equipment has become more specialized and increased in quality. As a result the difficulty rating of most river runs has changed. A classic example would be the
Colorado Riverin the Grand Canyon, which has swallowed whole expeditions in the past, leaving only fragments of boats but is now run safely by commercial outfitters hundreds of times each year, with relatively untrained passengers.

Risks in whitewater rafting stem from both environmental dangers and from improper behavior. Certain features on rivers are inherently unsafe and have remained consistently so despite the passage of time. These would include "keeper hydraulics", "strainers" (e.g. fallen trees), dams (especially low-head dams, which tend to produce river-wide keeper hydraulics), undercut rocks, and of course dangerously high waterfalls. Rafting with experienced guides is the safest way to avoid such features. Even in safe areas, however, moving water can always present risks -- such as when a swimmer attempts to stand up on a rocky riverbed in strong current, risking foot entrapment. Irresponsible behavior related to rafting while intoxicated has also contributed to many accidents.
To combat the illusion that rafting is akin to an amusement park ride, and to underscore the personal responsibility each rafter faces on a trip, rafting outfitters generally require customers to sign waiver forms indicating understanding and acceptance of potential serious risks. Rafting trips often begin with safety presentations to educate customers about problems that may arise.
Due to this the overall risk level on a rafting trip with experienced guides using proper precautions is low.Fact|date=June 2007 Thousands of people safely enjoy raft trips every year.
Issues with rafting
Like all wilderness sports, rafting has to balance the conflict between nature protection and nature use. Because of frequent problems in the past, some rivers now have regulations restricting or specifying the annual and daily operating times.
Conflicts have also arisen with environmentalists when rafting operators, often in co-operation with municipalities and tourism associations, alter the riverbed by dredging and/or blasting in order to eliminate safety risks or create more interesting whitewater features in the river. Incongruously these measures usually are only temporary, since a riverbed is subject to permanent changes.
On the other hand, rafting contributes to the economy of many alpine regions which in turn may contribute to the protection of rivers from
hydroelectric powergeneration and other development. Additionally, white water rafting trips can promote environmentalism. By experiencing first hand the beauty of a given river, individuals who would otherwise be indifferent to the environmental concerns of an area may gain a strong desire to protect and preserve that area because of a positive outdoors experience.
