A kayak a small, narrow watercraft which is typically
propelled by means of a double-bladed paddle. The word kayak originates
from the Greenlandic word qajaq.
The traditional kayak has a covered deck and one or more cockpits, each
seating one paddler. The cockpit is sometimes covered by a spray deck
that prevents the entry of water from waves or spray, differentiating
the craft from a canoe. The spray deck makes it possible for suitably
skilled kayakers to roll the kayak: that is, to capsize and right it
without it filling with water or ejecting the paddler.
The kayak was first used by the indigenous
Aleut, Inuit,
Yupik, and possibly
Ainu hunters in subarctic regions of the
world.
