Forward Sweep Stroke:
Making a broad sweeping stroke on one side of the kayak turns the boat in the opposite direction.
Sweep Stroke
In executing the sweep, the angle of your arms is the same as with the low brace, but your control-hand wrist is turned so the power face of the blade addresses the water. Assuming you are right-handed, reach forward and out on that side and stroke through the better part of a half-arc of a circle. The sweep will push you in the opposite direction (that is to the left), while still maintaining momentum.
A variation is the reverse sweep. Actually, it's a double reverse, since it is done in a reverse manner and has the reverse affect: Sweep from stern to bow on the right side, and the kayak turns in that direction. A right-side powerstroke followed by a right side reverse sweep is one way to execute a 90 degree turn to starboard.
The Stern Rudder
The stern rudder is easily learned, but you should use it sparingly as a tool for steering correction.
To rudder; plant the blade to the rear of the cockpit—but remember your hydrodynamics. For the rudder to be effective, the boat must be moving forward against the rudder's resistance.
The disadvantage of the rudder is that it is a drag, literally speaking. The rudder retards forward movement. When possible and comfortable use a forward sweep instead. You get steering control while maintaining momentum. And remember that momentum—movement relative to the water—is the key to stability. An injudicious stern rudder the middle of a set of waves can leave you caught in the trough, with angry white stuff looming over your head and licking its chops in anticipation of chewing on you.
