Steering If you have a boat with a rudder, it is a very good idea to learn how to handle your boat without using it. Certainly a rudder is invaluable in a following sea, but like any mechanical system, it can fail. Again, it goes beyond the scope of this web page to describe the many techniques for steering, but you will be well served to develop a large repertoire of steering maneuvers. In most sea kayaking situations, the forward sweep stroke will serve the purpose. The forward sweep stroke is simply a forward paddling stroke where you extend the paddle in a broad arc on the side opposite to the direction of the turn.
Sea kayaks turn much easier when tilted slighty.
In general, other techniques for turning generally will slow your boat down. The canoe-style rudder stroke is not recommended since it doesn't offer much stability and slows you down. However if you use a high or low brace as a rudder combined with a strong lean into the turn, you can effect a very quick and stable turn, though it will also slow you down. There are many other strokes for turning and moving your boat. The worst that can happen is you get wet.
