A recreational kayak is a type of kayak that is designed for the casual paddler interested in recreational activities on a lake or flatwater stream; they presently make up the largest segment of kayak sales. Compared to other kayaks, recreational kayaks are characterized by having a larger cockpit opening for easy entry and exit and a wider beam (27–30 inches) for more stability on the water and are generally less than twelve feet in length, which makes them slower than a longer boat would be, but lighter, easier to handle in and out of the water, and less expensive. Due to the wider hull, recreational kayaks will not track (maintain a straight line) as well as longer, narrower models. They generally have limited cargo carrying capacity. Using less expensive materials like rotomoldedpolyethylene and including fewer options helps keep these boats inexpensive.
