Surfing Huge Waves

Other equipment includes a leash (to stop the board from drifting away after a wipeout, and to prevent it from hitting other surfers), surf wax, traction pads (to keep a surfer's feet from slipping f the deck the board), and fins (also known as skegs) which can either be permanently attached (glassed-on) or interchangeable.
Sportswear designed or particularly suitable for surfing may be sold as boardwear (the term is also used in snowboarding). 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. A newer introduction is a rash vest with a thin layer titanium to provide maximum warmth without compromising mobility.
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 the earliest surfboards, but now benefit from modern innovations in surfboard shaping and fin design. Competitive longboard surfers need to be competent at traditional walking maneuvers, as well as the short-radius turns normally associated with shortboard surfing.
The modern shortboard began life in the late 1960s and has evolved into today's common thruster style, defined by its three fins, usually around 6 to 7 feet (1.8 to 2.1 m) in length. The thruster was invented by Australian shaper Simon Anderson.
