The paddle used is usually a 'wing paddle' (although standard asymmetrical paddles can also be used) – wing paddles have blades which are shaped to resemble a wing or spoon, creating lift and increasing the power and stability of the stroke. There are many variations of wing paddles, ranging from longer and narrower options for more stability ...
The paddling technique is different from the European style paddle though the same motion is how the Greenland paddle works with its narrow blade. It is most often used in racing, but also sees some limited use in recreational paddling such as touring. A set of wing paddles
Wingtip vortices are circular patterns of rotating air left behind a wing as it generates lift. [1]: 5.14 The name is a misnomer because the cores of the vortices are slightly inboard of the wing tips. [2]: 369 Wingtip vortices are sometimes named trailing or lift-induced vortices because they also occur at points other than at the wing tips.
Following the end of World War II, Dr. Sighard F. Hoerner was a pioneer researcher in the field, having written a technical paper published in 1952 [7] that called for drooped wingtips whose pointed rear tips focused the resulting wingtip vortex away from the upper wing surface. Drooped wingtips are often called "Hoerner tips" in his honor.
The Sweep Roll represents one of the earliest techniques employed in kayaking. In this maneuver, the paddler initiates an arc motion with the paddle, starting at the bow of the kayak. This technique facilitates the paddler's proximity to the water's surface, providing a tactical advantage in aerated water conditions.
Wing warping was an early system for lateral (roll) control of a fixed-wing aircraft or kite. The technique, used and patented by the Wright brothers , consisted of a system of pulleys and cables to twist the trailing edges of the wings in opposite directions.
The paddling stroke is similar to that of most other racing canoe paddling strokes, involving primarily core and lat strength. Generally, each paddler paddles on the opposite side from the paddler in directly front (for example, in an OC6, paddlers in seats 1, 3, and 5 paddle on one side, while paddlers in seats 2 and 4 paddle on the other side).
The wing is designed so that the angle of incidence is greater at the wing roots and decreases across the span, becoming lowest at the wing tip. This is usually to ensure that at stall speed the wing root stalls before the wing tips , providing the aircraft with continued aileron control and some resistance to spinning .
