A kayak is a small human-powered boat that traditionally has a covered deck, and one or more cockpits, each seating one paddler who strokes a double-bladed paddle. In a kayak the paddler faces forward, legs in front.
The three types of Canoe sprint kayaks (sometimes termed 'sprint boats') are K-1 (single paddler), K-2 (two paddlers) and K-4 (four paddlers).
A flatwater racing K1's maximum length governed by the ICF is 17 feet (5.2 m). These boats are raced at the Olympic level by men and women over courses of 200, 500 and 1000 meters. Women compete on 1000 meters since 1997.
