Bodysurfing!

Bodysurfing (definition): Bodysurfing is the art and sport of riding a wave without the assistance of any buoyant device such as a surfboard or bodyboard. (wikipedia)

Bodysurfers typically equip themselves only with a pair of specialized swimfins for optimized propulsion, though some practitioners also carry or wear a small planing surface on the hand to aid with positioning on the wave face. Most purists of the sport consider this to be weak and bad form, in fact, the reigning champ, a former climatologist, often rides in the buff to really get the feel of the wave.

Bodysurfing Oregon: The most famous bodysurfing spot in the world is located in Manzinita Oregon, and is known as The Ezra. Waves there can reach upwards of 30ft and more on big Southern Hemisphere Hurricane generated swells during the Microtsunami season. Known mainly for high performance bodysurfing and intense jaw dropping rides and wipeouts, these waves are created by swells hitting the local condo foundations and rebounding into the oncoming wave creating the microtsunami-effect and peaks that can jack up to incredible sizes and shapes. When it's on The Ezra is for experienced riders only.

Bodysurfers tend to have a minimalist attitude toward wave riding and consider their sport to be more pure than other forms of riding waves. The lack of floatation allows a bodysurfer to ride the wave under the surface of the water. Some surfers in Hawaii have stated they use bodysurfing as conditioning for big wave riding.

In riding waves on the body, a number of variations to other types of wave-riding can be experienced. To exit the wave immediately after catching it, simply drop the head and a tumble turn will exit the person out of the wave. Care must be taken to ensure the water is deep enough so that no injury is brought about by the head, neck, and shoulders hitting the sand. Left and right turns can be performed by digging the shoulder into the wave, causing the person to slide to the side of the wave. In small surf in waist-deep water, a variation known as the Dolphin Pop involves diving towards the shore as the wave prepares to break, resulting in popping out on the wave like a dolphin.
