[2] Crews or individuals race over 200 m, 500 m, 1000 m, or 5000 m, with the winning boat being the first to cross the finish line.
A K-3 kayak has been developed in South Africa for use in the Fish River Canoe Marathon.
[3] Modern sprint kayaks are generally made of lightweight composite materials such as carbon fiber and fiberglass; wood was previously used on older kayaks along with steel for some sections of the boat (i.e. the rudder).
Due to this, they are not intended to be used in anything other than flat watercourses - they can capsize and/or be dragged underwater in moderate waves.
The beam of a flatwater boat is typically barely wider than the hips of its paddlers and requires the paddler to bend their legs in the boat, allowing for a long and narrow shape to reduce drag.
