The kayaker's talent and level of experience have a direct bearing on the speed. A kayaker with more excellent expertise can paddle at a pace of up to six miles per hour, whereas a novice can only manage approximately two and a half miles per hour (or two knots). A sit-on-top kayak more than 10 feet in length is considered a speedier option. The Perception Tribe and the Sundolphin Bali are two examples of sit-on-top kayaks that are among the quickest in their class.
