Paracanoe competitions are contested in either a va'a (V), an outrigger canoe (which includes a second pontoon) with a single-blade paddle, or in a kayak (K), a closed canoe with a double-bladed paddle. All international competitions are held over 200 metres in single-man boats, with three event classes in both types of vessel for men and women depending on the level of an athlete's impairment. The lower the classification number, the more severe the impairment is - for example, VL1 is a va'a competition for those with particularly severe impairments.[3]
