Whitewater kayaks are generally made out of rigid, high impact plastic; usually polyethylene. They are shorter than other types of kayaks, ranging from 5.5 to 10 feet (2 to 3 metres) long. Modern design has moved toward shorter boats, which make them very maneuverable but slow. However, whitewater boats do not need inherent speed, because they move downriver with current. In "freestyle" competition ("kayak rodeo"), whitewater kayakers use features of rapids to do tricks, typically while remaining in one place on the river.

Ultra-low-volume kayaks that are designed to be paddled both on and below the surface of the water are used in Squirt Boating.
