Slalom

From KayakWiki

Slalom kayaking is a competitive type of kayaking, in which one attempts to navigate a slalom course in the fastest time possible. The slalom course consists of a set of gates arranged on a stretch of whitewater including obstacles such as rocks. The gates are pairs of coloured poles, suspended vertically above the water, between which the competitor must pass without touching. The gates must be navigated in sequence and may be required to pass through either downstream or upstream - at one time it was required that some gates be passed through in reverse.

In proper slalom competitions, only slalom kayaks are allowed.
