Riverboarding

A riverboarder floats down the Kern River at about 4,000 cfs

Riverboarding is the North American name for a boardsport in which the participant is prone on the board with fins on his/her feet for propulsion and steering. This sport is also known as hydrospeed in Europe and white-water sledging in New Zealand. Riverboarding includes recreational and the swiftwater rescue practice of using a high-flotation riverboard, designed for buoyancy in highly aerated water.

Origins

Riverboarding is believed to have originated in the late 1970s. It is claimed to have originated in France, when raft guides stuffed a burlap mail sack with life vests and went down rapids. Soon, riders adapted a personal submarine shell for their molds and the plastic version of the riverboard was born. Sometime in the late 1980s, Carlson began running rivers in California using an ocean bodyboard and ended up making his own board that was bigger, thicker and handles.
