High Quality Content by WIKIPEDIA articles! A sea kayak or touring kayak is a kayak developed for the sport of paddling on open waters of lakes, bays, and the ocean. Sea kayaks are seaworthy small boats with a covered deck and the ability to incorporate a spraydeck. They trade off the maneuverability of whitewater kayaks for higher cruising speed, cargo capacity, ease of straight-line paddling, and comfort for long journeys.
