A recreational kayak is designed for the casual use such as fishing, photography, or an easy paddle on a lake or flatwater stream. Recreational kayaks are generally have larger cockpit openings for easy entry and exit and a wider beam for more stability on the water. Many are around twelve feet in length, which makes them slower than a longer boat would, but also much lighter and easier to handle. Most recreational kayaks use less expensive materials like rotomolded polyethylene to help keep these boats inexpensive.
