a kayak is a narrow watercraft where you use 2 bladed paddles

Kayak
A kayak is 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
(British English) – small boat, pointed at both ends, propelled by paddlers who kneel or sit on a raised seat and use paddles which usually have a blade at one end only. A touring canoe is normally used by two people. A canoe is usually open on top, but can be decked over (i.e. covered, similar to a kayak). A canoe is typically human-powered, though it may also be powered by sails or a small electric or gas motor. Paddles may be single-bladed
