| - | Below are stroke tips picked up from fellow paddlers, blogs, videos, etc. This is an attempt at detailing the ideal stroke. Given the differences in paddling philosophies, bodies and abilities this is not meant to be how we should all paddle. It's a framework to think about the stroke as we all find what works best for each of us. For more expert advice, visit the resources and video sections below and/or seek out acknowledged experts for lessons. And maybe keep in mind that there has been a fair amount of variety in the stroke technique of the very best and most successful surfski open ocean racers. | + | **Below are stroke tips** picked up from fellow paddlers, blogs, videos, etc. This is an attempt at detailing the ideal stroke.

Note also that a good part of the advice below is** coming from sprint kayak instructors**. Their emphasis on effective power can be helpful in general in terms of good technique, but keep in mind that while your technique may be basically the same, if may only be natural to scale back how much power you apply at the catch and early part of your stroke when you are **going for much greater distances** than sprint kayakers typically race. |

| - | Along the way you will probably notice that many paddlers have strokes that do not necessarily look much like what is described below, but their strokes are effective, they can catch waves, and they have a lot of fun. For most of us that is the bottom line! If you are not young and an aspiring Olympian, you probably don't need to get excessively enmeshed in a search for perfect technique (if you want to, then fine, but please keep in mind what will best keep paddling enjoyable and a lifelong recreation for you).

| - | * Pause at the front of the stroke. Feel the run of the boat. (This is not really a complete stop in movement, but rather a short moment between when the powering blade comes out of the water and the front blade starts to descend toward the water. This "pause" seems to be the dominant technique as of 2020, but some paddlers instead adopt a more continuous cycle without what looks like a short moment with the front hand kept at the same height as the recovery hand is coming up) | + | * "Pause" at the front of the stroke?

This is how Ivan Lawler likes to describe the power phase. We suspect it is more accurate to describe it as a combination of down and back. Your legs are in front of you, not under you, and your rotation is automatically feeding into backward motion. You can generate downward force as long as your paddle blade has not reached perpendicular. Lawler may be focusing on this first force part of the stroke/catch as downward because that is where the blade should be most positively angled and the most downward force can be applied. |
| * The catch arm should be almost straight. (some bend is okay - see what we say below in the Drive section about arm bend. The catch arm may be straight or close to straight at the end of setup, but as the blade reaches submersion there can be/should be some arm bend as soon as Drive is beginning) | * The catch arm should be almost straight.

| - | * Put weight down on the paddle, not pulling back. To offset the weight transfer down slightly shift your upper body weight to the non-stroke side. This is subtle, but it will keep your boat flat and allow for a much greater transfer of power. Think about a door with the hinge being along the paddle shaft and the door swinging wide over the non-stroke side of the boat. (//If you watch videos of good sprint kayakers the shift to keep the boat balanced is not necessarily that subtle - you will see their non-stroke side bow out and their torso shift to the non-stroke side pretty significantly - but keep in mind that this may be augmented for sprinting as opposed to what is adequate for a longer distance surfski stroke.)// | + | * Put weight down on the paddle, not pulling back.

| - | * <del>Keep lower arm straight or almost straight. Imagine you are pivoting around the spot with the blade stationary in the water; boat moves past the blade, not vice a versa.</del> This advice is a bit off… You do not want to be bending your power side arm excessively or arm paddling (trying to use your biceps instead of rotating), but as soon as power starts to be applied for most paddlers there is a slight bit of bend in the arm. Max power from the legs and rotation cannot be fully applied by most paddlers with an arm that stays completely straight. Also you want the wing to follow its natural drift outward while staying perpendicular to your boat. If you force a completely straight arm throughout your power phase, are you still letting your blade follow its most efficient path? And how smoothly can you make a rapid transition between completely straight and the fairly bent recovery position? The explanation and visual from Ivan Lawler's video ([[https://youtu.be/CL_h6lLaNMM|Day Six Lower Arm]]) is better than we can explain with text. He calls this slight arm bend "somewhere between straight and (//what he calls//) broken". This arm bend can be a little hard to see in paddler videos between the catch and exit, but if you slow down technique videos (e.g. with youtube playback speed settings) you should be able to see it more easily and how quickly the transition occurs between this very slight bend (where Mr. Lawler says you are basically "holding on" with the lower arm) during power application and when the lower arm rapidly bends during recovery. | + | * <del>Keep lower arm straight or almost straight.

| - | **"Ventilation** is what you call it when the paddle sucks air down the back of the blade. Many people call it cavitation, but that is when a propellor spins so fast that it creates a vacuum behind the blade (//Ed. Note: And when imperfections in a blade contribute to vacuum formation//). Neither is any good, but what your average kayaker creates is ventilation. The reason it is no good is you are moving air instead of water. Air weighs a lot less than water and if there is air behind your paddle instead of water the mass of water you are moving is decreased and thus creating the same momentum requires you expend more energy. | + | **"Ventilation** is what you call it when the paddle sucks air down the back of the blade.

| - | There are two ways of creating ventilation. One is by bringing the air down with the blade as you insert it into the water. The other is to pull air down the back of the paddle as you apply power. Both can be avoided by being sure your blade is fully submerged before applying power. A clean entry will not bring down much air and the small area near the top of the blade is less likely to ventilate." | + | There are two ways of creating ventilation.

| ==== Bracing ==== | ==== Bracing ==== | ||
| - | * **Low Brace **- typically putting the non-power side of one blade (occasionally low braces are done with the blade's power side in canoes) more or less flat on the water surface at a 45 degree angle behind you. Your wing paddle(([[:paddles|]])) will generally be as close to horizontal as practical given that it has to angle over your boat. Both hands are kept low vertically. Sometimes people rest the paddle on their legs or lap. (one of Oscar Chalupsky's energy saving tips and how Boyan Zlatarev teaches it) . Boyan teaches a slight lean to the side that you brace on. You can lean more to the brace side if you need to apply more weight on the brace, but the point is to keep your boat upright - generally you do not lean a lot and you just apply very light pressure to maintain contact to sense the available support while minimizing drag and speed loss. This is the kind of brace used by surfskiers (OC's also use a low brace with their single blade paddles). You need to practice and get **completely** comfortable with both sides (if you feather((See [[:terminology#feather|Feather]])) your blade angles, bracing on one side will likely seem more awkward at first). This brace is also often used for support on the side you are turning toward if you are on a wave. With more pressure it can act more like a rudder assisting sidewise turning but also reducing speed more. | + | * **Low Brace **- typically putting the non-power side of one blade (occasionally low braces are done with the blade's power side in canoes) more or less flat on the water surface at a 45 degree angle behind you.

| + | * **Exceptions: **As with many things, there can be exceptions to the brace position just described. If you are in very choppy water and/or in waves that are coming from one or both sides behind you, when you brace you may want to keep your blade farther forward rather than behind you at a 45 degree angle, so your paddle is less likely to get submerged/surprised by side/backside waves which would otherwise cause you to pull yourself into the water when you try to recover your bracing blade. Similarly in such conditions it is also a good idea to concentrate on keeping your forward stroke blade recovery no later than beside your body (or earlier) to reduce the likelihood of the finish of your stroke coinciding with a wave landing on top of and trapping your recovering blade. | ||
| * **High Brace **- recovery support and sharp turn stroke (high brace turn) on one side with higher (vertically) hand positions using the power side of blade. Commonly used by sea and white water kayakers - proper technique is critical (take care about not letting your hands get too high or too far away from your body - watch video immediately below) because it can put significant stress on your shoulders. | * **High Brace **- recovery support and sharp turn stroke (high brace turn) on one side with higher (vertically) hand positions using the power side of blade.
