In calm conditions,
a sweep stroke is usually sufficient to turn a kayak, but when
the wind blows, turning a kayak may require something more. Depending
on the relative direction of the wind and the direction you want
to turn, some strokes will work more effectively than others.
In choosing which strokes to use, it’s helpful to understand
how the forces imparted by the wind and the water affect the directional
control of a kayak. You don’t have to struggle in the wind
if you use strokes that let the wind do some of the work for
you.

As
the kayak moves forward through the water, the bow and stern
encounter different forces. The bow moves forward into undisturbed
water and pushes it aside. At the stern, the water moves back
in to fill the void created by the passage of the middle of the
kayak, leaving turbulent water in the kayak’s path. In calm air, these forces are balanced on both sides of the kayak. But if the wind is blowing against the side of the kayak and pushing it sideways (and here we’ll
be considering the behavior of kayaks without rudders or skegs
or with those devices retracted), the bow meets more resistance
in the undisturbed water than the stern meets in the turbulent
water.
Because the stern of a forward-moving kayak has lower lateral
resistance than the bow, it is more readily pushed downwind.
The net result is that the kayak changes its heading, a phenomenon
referred to as weathercocking. From the paddler’s perspective,
the bow seems to be pulled up into the wind. As the paddling
speed increases, difference in lateral resistance between bow
and stern grows and the kayak veers more forcefully upwind.
Choosing your strokes to work in concert with the forces imparted
by the wind on the kayak will improve your performance and reduce
the effort required to manage your kayak. Turning the kayak in
the wind begins with good forward speed and by using the paddle
effectively on both sides of the boat. For turning in wind, you’ll
need good basic skills with the sweep stroke and bow and stern
rudders.
The forward sweep stroke is the fundamental stroke for turning
a sea kayak. The sweep is a modified forward stroke that adds to
forward momentum and causes the kayak to turn. Consider a turn
to the right—the
stroke is preceded by an initial upper torso twist clockwise and
then the left paddle blade is planted well forward on the left side
of the kayak. During the stroke, you unwind the lower torso to turn
the kayak against the resistance of the paddle. At the end of the
sweep, you’ll have to withdraw the paddle blade from the
water quickly or it will reduce the momentum of your turn.
The sweep stroke uses only one paddle blade, but you can use both
blades to turn. For more turning power, combine two strokes into
a smooth sequence, and follow the sweep stroke on one side with a
bow rudder or a stern rudder on the opposite side.
Rudder strokes are performed by placing the blade either forward
or aft of your hips and holding it in a static position. The power
face of the paddle is the side normally facing you (usually the
concave face bearing the manufacturer’s label) and the back
face is the side normally facing away from you. For a bow rudder
in the wind, the paddle shaft is held in a nearly vertical orientation,
and the blade is placed in the water at a forward position near
or beyond your knees. The power face of the blade is toward the
kayak, with the leading edge of the blade rotated slightly outward,
creating an angle of attack that pulls the bow into the turn.
A stern rudder works in a very similar way but has the paddle shaft
in a more horizontal orientation, with the blade placed well aft
of your hip. The blade is in a nearly vertical plane and the power
face is toward the kayak. The paddle shaft is positioned to create
an angle of attack so that the water pushes against the back side
of the blade, which then pushes the stern to the outside of the turn.
Effective bow and stern rudder strokes require subtle adjustments
of blade position and angle of attack.
