Surfing
From Wikipedia, the free encyclopedia
- This article focusses on stand-up surfing. For other uses see Surfing (disambiguation)
Surfing refers to a person or boat riding down a wave and thereby gathering speed from the downward movement. Most commonly, the term is used for a surface water sport in which the person surfing is carried along the face of a breaking ocean wave (the "surf") standing on a surfboard. Surfboards can also be used on rivers on standing waves. Both are sometimes called stand-up surfing, to distinguish it from bodyboarding, in which the individual riding the wave does not stand up on the board and only partly raises his upper body from the board.
Two major subdivisions within contemporary stand-up surfing are reflected by the differences in surfboard design and riding style of longboarding and shortboarding. In tow-in surfing (most often, but not exclusively, associated with big wave surfing), a surfer is towed into the wave by a motorized water vehicle, such as a jetski, generally because standard paddling is often ineffective when trying to match a large wave's higher speed.
Depending on wave size and direction and on wind conditions, also sailboats surf, namely on larger waves on open sailing waters. Unlike "surfers", sailors usually do not surf in beach waves, and they usually do not go out in order to surf; instead, the wave and wind conditions may let them boat surf while during a sailing trip. More recently, the same principle of craft-based surfing has been increasingly used by kayakers, notably in the sport of playboating, which is mostly carried out on rivers (see playspot).
Surfing-related sports such as paddleboarding and sea kayaking do not require waves, and other derivative sports such as kitesurfing and windsurfing rely primarily on wind for power, yet all of these tools may as well be used to ride waves.

[edit] Hydrodynamics
Swell is generated when wind blows consistently over a large area of open water, called the wind's fetch. The size of a swell is determined by the strength of the wind and the length of its fetch and its duration. So, surf tends to be larger and more prevalent on coastlines exposed to large expanses of ocean traversed by intense low pressure systems.
Local wind conditions affect wave quality, since the ridable surface of a wave can become choppy in blustery conditions. Ideal surfing conditions include a light to moderate strength "offshore" wind, since this blows into the front of the wave making it barrel or tube.
The factor which most determines wave shape is the topography of the seabed directly behind and immediately beneath the breaking wave. The contours of the reef or bar front becomes stretched by diffraction; one must be sensitive to each of these factors. Each break is different, since the underwater topography of one place is unlike any other. At beach breaks, even the sandbanks change shape from week to week; therefore, it takes a commitment for surfers to find good waves (a skill dubbed "broceanography" by a few California surfers). That is why enthusiasts have traditionally regarded surfing as more of a lifestyle than merely a sport. Nowadays, however, surf forecasting is aided by advances in information technology, whereby mathematical modeling graphically depicts the size and direction of swells moving around the globe.
The regularity of swell varies across the globe and throughout the year. During winter, heavy swells are generated in the mid-latitudes, when the north and south polar fronts shift toward the Equator. The predominantly westerly winds generate swells that advance eastward. So, waves tend to be largest on west coasts during the winter months. However, an endless train of mid-latitude cyclones causes the isobars to become undulated, redirecting swells at regular intervals toward the tropics.
East coasts also receive heavy winter swells when low-pressure cells form in the sub-tropics, where their movement is inhibited by slow moving highs. These lows produce a shorter fetch than polar fronts, however they can still generate heavy swells, since their slower movement increases the duration of a particular wind direction. After all, the variables of fetch and duration both influence how long the wind acts over a wave as it travels, since a wave reaching the end of a fetch is effectively the same as the wind dying off.
During summer, heavy swells are generated when cyclones form in the tropics. Tropical cyclones form over warm seas, so their occurrence is influenced by El Niño & La Niña cycles. Their movements are unpredictable. They can even move westward, which is unique for a large scale weather system. In 1979, Tropical Cyclone Kerry wandered for three weeks across the Coral Sea and into Queensland before dissipating.
The quest for perfect surf has given rise to a field of tourism based on the surfing adventure. Yacht charters and surf camps offer surfers access to the high quality surf found in remote, tropical locations, where tradewinds ensure offshore conditions. Since winter swells are generated by mid-latitude cyclones, their regularity coincides with the passage of these lows. So, the swells arrive in pulses, each lasting for a couple of days, with a couple of days between each swell. Since bigger waves break in a different configuration, a rising swell is yet another variable to consider when assessing how to approach a break.

[edit] Artificial reefs
The value of good surf has even prompted the construction of artificial reefs and sand bars to attract surf tourism. Of course, there is always the risk that one's holiday coincides with a "flat spell." Wave pools aim to solve that problem, by controlling all the elements that go into creating perfect surf, however there are only a handful of wave pools that can simulate good surfing waves, owing primarily to construction and operation costs and potential liability.
The availability of free model data from the NOAA has allowed the creation of several surf forecasting websites.
[edit] Surfers and surf culture
Surfers represent a diverse culture based on riding the naturally occurring process of ocean waves. Some people practice surfing as a recreational activity while others demonstrate extreme devotion to the sport by making it the central focus of their lives. Within the United States, surfing culture is most dominant in California, Florida and Hawaii. Some historical markers of the culture included the woodie, the station wagon used to carry surfers' boards, as well as boardshorts, the long swim suits typically worn while surfing.
The sport of surfing has become so popular that it now represents a multi-billion dollar industry specially in clothing and fashion markets. Some people make a career out of surfing by receiving corporate sponsorships.
[edit] Maneuvers
Surfing begins when the surfer finds a ridable wave on the horizon and then attempts to match its speed (by paddling or sometimes, by tow-in). Once the wave has started to carry the surfer forward, the surfer jumps to his feet and proceeds to ride down the face of the wave, generally staying just ahead of the breaking part (white water) of the wave (in a place often referred to as "the pocket" or "the curl"). A common problem for beginners is being unable to catch the wave in the first place, and one sign of a good surfer is the ability to catch a difficult wave that other surfers cannot.
Surfers' skills are tested not only in their ability to control their board in challenging conditions and/or catch and ride challenging waves, but by their ability to execute various maneuvers such as turning and carving. Some of the common turns have become recognizable tricks such as the "cutback" (turning back toward the breaking part of the wave), the "floater" (riding on the top of the breaking curl of the wave), and "off the lip" (banking off the top of the wave). A newer addition to surfing has been the progression of the "air" where a surfer is able to propel oneself off the wave and re-enter. Some of these maneuvers are now executed to extreme degrees, as with off-the-lips where a surfer over-rotates his turn and re-enters backward, or airs done in the same fashion, recovering either with re-rotation or continuing the over-rotation to come out with his nose forward again.
"Tube riding" is when a surfer maneuvers into a position where the wave curls over the top of him or her, forming a "tube" (or "barrel"), with the rider inside the hollow cylindrical portion of the wave. This difficult and sometimes dangerous procedure is arguably the most coveted and sought after goal in surfing.
"Hanging Ten" and "Hanging Five" are moves usually specific to longboarding. Hanging Ten refers to having both feet on the front end of the board with all of the surfer's toes off the edge, also known as noseriding. Hanging Five is having just one foot near the front, toes off the edge. Hanging Ten was first made famous by James (rip) Carman from the early Californian surfing beaches.

[edit] Learning to surf
Many popular surfing destinations, such as Hawaii, California, Australia and Costa Rica, have surf schools that offer surfing lessons and surf camps. Surf camps for beginners and intermediates are multi-day lessons that focus on the basic fundamentals of surfing. They are designed to take new surfers and help them become proficient riders. All-inclusive surf camps are surf camps which offer typically overnight accommodations, meals, surfing lessons and surfboards.[citation needed]
Typical surfing instruction is best performed in a one-on-one lesson format, but can also be done in a group setting. Popular surf locations such as Hawaii and Costa Rica offer perfect surfing conditions for beginner surfers, as well as, more challenging conditions for advanced surfers. Surf spots more conducive to instruction typically display a different criteria of conditions suitable for learning. Of these, sand bars or sandy bottom breaks with consistent waves are of the utmost importance. Also, having plenty of room to practice is a big plus.
[edit] Equipment
Surfing can be done on various pieces of equipment, including surfboards, bodyboards, wave skis, kneeboards and surf mat. Surfboards were originally made of solid wood and were generally quite large and heavy (often up to 12 feet (3.7 m) long and 100 pounds / 45 kg). Lighter balsa wood surfboards (first made in the late 1940s and early 1950s) were a significant improvement, not only in portability, but also in increasing maneuverability on the wave.
Most modern surfboards are made of polyurethane foam (with one or more wooden strips or "stringers"), fiberglass cloth, and polyester resin. An emerging surf technology is an epoxy surfboard, which are stronger and lighter than traditional fiberglass. Even newer surfboard designs incorporate materials such as carbon fiber and springy 'firewire'.
Equipment used in surfing includes a leash (to stop a surfer's board from washing to shore after a "wipeout", and to prevent it from hitting other surfers), surf wax and/or traction pads (to keep a surfer's feet from slipping off the deck of the board), and "fins" (also known as "skegs") which can either be permanently attached ("glassed-on") or interchangeable. In warmer climates swimsuits, surf trunks or boardshorts are worn, and occasionally rash guards; in cold water surfers can opt to wear wetsuits, boots, hoods, and gloves to protect them against lower water temperatures.
There are many different surfboard sizes, shapes, and designs in use today. Modern longboards, generally 9 to 10 feet (3.0 m) in length, are reminiscent of the earliest surfboards, but now benefit from all the modern innovations of surfboard shaping and fin design.
The modern shortboard began its life in the late 1960s evolving up to today's common "thruster" style shortboard, a three fin design, usually around 6 to 7 feet (2.1 m) in length.
Midsize boards, often called funboards, provide more maneuverability than a longboard, with more floatation than a shortboard. While many surfers find that funboards live up to their name, providing the best of both surfing modes, others are critical. "It is the happy medium of mediocrity," writes Steven Kotler. "Funboard riders either have nothing left to prove or lack the skills to prove anything."[1]
There are also various niche styles, such as the "Egg", a longboard-style short board, the "Fish", a short and wide board with a split tail and two or four fins, and the "Gun", a long and pointed board specifically designed for big waves.
[edit] Dangers
[edit] Drowning
Surfing, like all water sports, carries the inherent danger of drowning. Although a surfboard may assist a surfer in staying buoyant, it cannot be relied on for floatation, as it can be separated from the user.[2] The use of a leash, which is attached at the ankle or knee, keeps the surfer connected to the board for convenience but should not be used as a safeguard to prevent drowning. The established rule is that if the surfer cannot handle the water conditions without his or her board then he or she should not go in. Drownings have occurred as a result of leashes becoming caught on reefs holding the surfer underwater. In very large waves such as Waimea or Mavericks being attached to the board may be undesirable as it can be pulled for long distances in the whitewater, holding the surfer underneath the wave. Surfers will often surf in pairs or groups as a safeguard.
[edit] Collisions
Anything that a surfer's body can come in contact with may be dangerous. This includes sand bars, rocks, reefs, surfboards, and other surfers.[3] Collisions with these objects may cause unconsciousness or even death.
Many surfers jump off bridges, buildings, wharves and other structures to reach the surf. If the timing is wrong they can either hurt themselves or their equipment.[4]
A large number of injuries, up to 66%,[5] are caused by impact of either a surfboard nose or fins with the surfer's body. Surfboard fins can cause deep lacerations and cuts as well as bruising due to their shape. While these injuries can be minor, they can open the skin to infection from the sea; groups like SAS campaign for cleaner waters to reduce this risk.
[edit] Sea life
Various types of sea life can cause injuries and even fatalities. Depending on the location of the surfing activity, animals such as sharks, stingrays, seals and jellyfish may be a danger to surfers.[6]
[edit] Local surfers
Local surfers can be violent when it comes to protecting their surf break from tourists or outside surfers. This is called "localism." Some surfers have been known to form gangs that surf in a certain break or beach and fiercely protect their "territory" from outsiders. These surfers are often referred to as "surf punks" or "surf nazis." The local surfer gangs in Malibu and in Hawaii, known as Da hui, have been known to threaten tourists with physical violence for invading their territory.
