Kayaking is the use of a kayak for moving over water. It is distinguished from canoeing by the sitting position of the paddler and the number of blades on the paddle. A kayak is a low-to-the-water, canoe-like boat in which the paddler sits facing forward, legs in front, using a double-bladed paddle to pull front-to-back on one side and then the other in rotation. Most kayaks have closed decks, although sit-on-top and inflatable kayaks are growing in popularity as well. History Kayaks were created thousands of years ago by the Inuit, formerly known as Eskimos, of the northern Arctic regions. They used driftwood and sometimes the skeleton of whale, to construct the frame of the kayak, and animal skin, particularly seal skin was used to create the body. The main purpose for creating the kayak, which literally translates to "hunter's boat" was for hunting and fishing. The kayak's stealth capabilities allowed for the hunter to sneak up behind animals on the shoreline and successfully catch their prey. In the 1740s, Russian explorers led by the Danish explorer Vitus Bering came in contact with the Aleutians, who had taken the basic kayak concept and developed multiple designs specifically for hunting, transportation, and environmental conditions. They soon recognized the Aleutians were very skillful at hunting sea otters by kayak. Because otters were a popular commodity in Europe and Asia, they would exploit and even kidnap Aleutians and keep them aboard their ships to work and hunt. By the mid-1800s the kayak became increasingly popular and the Europeans became interested. German and French men began kayaking for sport. In 1931, Adolf Anderle was the first person to kayak down the Salzachöfen Gorge, which is believed to be the birthplace of modern-day white-water kayaking. Kayak races were introduced in the Berlin Olympic Games in 1936. In the 1950s, fiberglass kayaks were developed and commonly used, until the 1980s when polyester and polyethylene plastic kayaks were introduced. Kayaking progressed as a fringe sport in the U.S. until the 1970s, when it became a mainstream popular sport. Now, more than 10 white water kayaking events are featured in the Olympics. While kayaking represents a key international watersport, few academic studies have (to date) been conducted on the role kayaking plays in the lives and activities of the public Design Kayaks can also be classified by their design and the materials from which they are made.
