Paddling straight?
I was out today with a friend who is new to paddling and I saw her
have a problem I've only seen a few times before and can't explain. She was paddling a poly Prijon Seayak and could not get it to track straight to save her life. The rudder was up (control line was broken) but since there was not much wind I figured it wouldn't matter much. We were paddling with the tide the whole way and it was pretty strong at times. It got so bad that at times she was paddling entirely on the right side of her boat and still turning to the right! I watched her stroke thinking maybe she was dragging the paddle at the end and creating a rudder effect like with a J stroke but I didn't see that happening. Her stroke isn't perfect, but I didnt' see anything that would create the situation she was experiencing with great frustration. Finally we found a sandy bank and switched boats with her in my old Perception Sea Lion and me in the Seayak and it didn't help. She still couldn't get the boat to track straight. I found the Seayak a bit more skittish on the water (the wind picked up at times) but didn't have any problem paddling it straight. Now I've seen this happen with at least one person before (in different boats) and we never could figure out what was causing it. We tried changing the paddler's balance, paddle grip, and other variables without success. I keep thinking it must have to do with the strong tidal current that we were paddling with but I'm not sure I can figure out why it would be and why I wouldn't have been similarly affected. At one point when she was in the Sea Lion I had her turn the boat around and paddle against the current and she said it was "better". Can anyone shine the magic light of experience on this for me? Thanks, John |

Perhaps she was sitting off-center in the boat or leaning a bit,
popping the boat on an edge and therefore turning it by the curvature of the craft? I would think that this much lean would have been detectable by you, but maybe not. Tracking can also be affected by the trim of the boat, but unless you had it loaded or your partner had -really- heavy feet (!), I doubt this would be an issue.

I was in a different boat than what I was used to and I was having a like
problem. The reason was that I was tense and was inadvertently pushing one knee up hard and it was throwing my whole balance out. After I stopped fighting with the boat and relaxed all was well. The people I was paddling with said that the boat looked mostly level but I think it was edging up with each stroke. -- "John/Charleston" wrote in message ...

My guess is that the current/wind was having more of an effect than you thought it might. However, the biggest problem that I have seen when people have trouble keeping their kayak going straight is directly related to their paddle stroke. Just out of curiosity, was this person left handed and using a feathered paddle? Typically, if someone is having trouble with the boat always going left (or right) it's because the angle of the paddle blade is not the same on both sides. It occurs most frequently with right handed paddlers and a failure to orient the left paddle blade such that the top of the blade is tilted slightly back. If they're holding the paddle correctly the blade on the control hand side will enter the water such that the top edge of the blade is tilted slightly toward the paddler. If they're not dropping their control hand elbow and bringing their control hand toward their should when placing the non-control hand blade in the water, the top edge will be tilted slightly forward and they'll end up scooping water instead of getting the same amount of power on the non-control hand side. A trick I use with beginners is to have the pause for just a second before putting the paddle blade in on each side and glance at the orientation of the blade to make sure that the angle is the same on both sides. |

My guess is that the current/wind was having more of an effect than you thought it might. Yeah, I've been thinking more about it and I'm thinking it was the current pushing the rear of the boat sideways. It wasn't her leaning as I had her paddle with a pronounced lean in both directions and it didn't help. I'm pretty sure it wasn't the paddle stroke since as I said she could paddle entirely on one side and still turn to that side. But i'm thinking if she wasn't going faster than the current it might have been grabbing the rear of the boat and pushing it in whatever direction it was tending towards already. The boats weren't loaded with much of anything but I'm not sure if that would have helped any. Maybe she just needed to get the boat moving faster? |

Yes, most kayaks are rigid structures....but when you push on one pedal
only, you tend to cause the kayak to lean to one side when the paddle stroke is on the opposite side of the foot pressure. Think about it for a moment and you'll see what I mean. It's a potential explanation for the steering problems, IMHO. I'm new to the sport and don't speak from a lot of experience...but logic tells me that it could be an explanation for steering problems. The other is that the strength of the strokes is uneven. If you paddle hard on one side but not the other, you slowly turn. I use this as a supplement to leaning or using a J stroke to stay on course.

How do you figure that? Being essentially a rigid structure, the boat won't respond any differently to pressure on one foot pedal than the other. Except when used to control a rudder, all the foot pedals do is provide support so the paddler can resist the force of the paddle stroke. The commonly repeated notion that one can steer a kayak by pushing on the foot pedals is nonsense. Steering is controlled by the paddle strokes and/or edging/leaning. |

It's just that I don't think it would make more than a trivial impact on the direction of the kayak. As I wrote, I've done an exercise in which we paddled forward pressing with the same foot as the paddle stroke, and then tried it pressing the opposite foot. I didn't notice any tendancy for the boat to go off course when I was pressing with the opposite foot and the instructor for the course that was suggesting the exercise is one of the most accomplished expedition kayakers in the world today.

If you paddle hard on one side but not the other, you slowly turn. It might seem that way but the strength of the stroke usually doesn't affect the direction of the kayak. Once you get up a bit of speed, unless you're trying to maintain a sprint pace, you don't to continue to paddle hard to keep up a decent hull speed. The difference in arm strength certainly wouldn't make much difference since the amount of effort required from your weakest arm is more than sufficient to keep up a good pace. What will affect the direction to a much greater degree is the synchronicity of your stroke. The strength of the stroke is only one aspect in achieving identical strokes on the left and right side. There is also the length of the stroke. For the strokes to be equal you need to put the blade in the water the same distance from the bow on both sides and exit at the distance as well. I'm betting that if you try paddling harder on one side that your very likely keeping the paddle in the water longer on that side as well. Secondly, there is the distance of the paddle away from the hull. If you've practice a sweep stroke you'll find that it's much more effective if paddle "draws a C" in the water so that the blade is a few feet from the boat when it is perpendicular with the cockpit than if the blade stays close to the boat throughout the stroke. It would seem obvious then, that if the stroke on the right side of the boat is further away from the hull than the stroke on the left side that you'll generate more turning motion from the stroke on the right side. If you experiment with a sweep stroke a bit you'll find that trying to turn the boat by pulling harder on the paddle doesn't accomplish much and that a slow but complete sweep will turn the boat quite nicely. Finally, the orientation of the blade will significantly impact the power generated by the stroke and if the angle is not the same you'll generate a much greater turning motion on one side. Typically this happens when using a feathered paddle and failing to turn the top edge of the blade toward you on the non-control hand side. When that happens the blade tends to slice down and scoop water rather that push water toward the stern. That would also tend to tilt the kayak to that side as you're bringing the paddle the paddle out (try putting a paddle blade in the water perpendicular to the boat and pulling it straight up and watch what happens). Instead of trying to control the boat with brute force try slowing down the stroke so that you can feel the effect of the length of the stroke, the distance of the paddle from the boat, and the angle of the paddle blades. With practice it won't take long before you can keep your strokes synchronous and only change them intentionally when you want to effect the direction of the boat. For example, make a normal stroke on one side, but do a sweep on the other. I use this as a supplement to leaning or using a J stroke to stay on course. Using a J stroke in a kayak is very inefficient. |

I think there was an earlier post suggesting that the current or Wind were
bigger factors and I played with this on the weekend. With a tail current I found that if I didn't keep straight in line with it, it would turn me toward which ever side it was presented. Based on this I eased off and made my effort in keeping down the current and presto less effort and true running. I would imagine that weather- cocking with the wind would be the same effect but above the water. To ensure I wasn't situating the experiment, I tried it with a much longer boat that tracks well and found that I didn't have the same experience, therefore my humbel deduction is that it probably applies to all boats but boats(Kayaks) that tend to turn more readily are more affected by current and wind. A bold supposition but thats what I discovered. Hope this wasn't motherhood. Craig Cotter "John Fereira" wrote in message .. .
