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; these being A (use of arms only), TA (use of trunk and arms), and LTA (use of legs, trunk, and arms).[2]
