When choosing between a skeg or rudder or neither, it comes down to personal preference. Using a skeg will help you stay on track, which is great if you’re not great at paddling and waiting in a straight line. A rudder is also an excellent addition, especially if you plan to fish while kayaking. It will allow you to change direction without using your hand.  If you’re an experienced kayaker, you might want to go with neither as you have the skills to handle the job.
