Tube Meaning in Surfing

A tube occurs when the crest of a wave arches over the surfer. This hollow space creates a tunnel of water around the rider and board. Surfers consider riding inside this space the ultimate goal of the sport. The rider must match the speed of the falling lip to stay inside. Small adjustments in weight determine whether the surfer exits or gets caught. Vision becomes limited to the circular opening at the end of the tunnel. A surfer disappears inside a hollow wave at a famous reef break. Dragging a hand in the water helps slow the board down for positioning. Maintaining a low crouch ensures the head does not hit the ceiling of water.
