I am not ready to concede that a "good" paddle design will never flutter, however others have used the same model paddle and had no problem. So, either the manufacturer has changed the paddle, the individual paddle is defective, or the paddler is doing something different. It is certainly not out of the question that the manufacturer made changes, but it would have to be fairly dramatic changes such as changing the shape which usually would be labeled as a different model. Any physical defects in the paddle itself should be evident to inspection, i.e. the blade is loosely glued to the shaft or something else that effects the flex of the paddle. More likely the paddler is doing something different. The subtleties of paddling technique leave a lot of room for variation, some of which will make flutter more likely. All it takes is a slight change in blade angle to completely eliminate the flutter. Just a degree or so will often do the trick. This will have virtually no effect on the drag of the paddle when drawn straight back if that is your preferred technique. However, a simple straight back stroke will take a single mass of water and accelerate it until you end the stroke. You can increase you efficiency slightly if the blade is always pushing against almost still water. This is part of the principle behind the efficiency of a wing paddle where the stroke angles out to the side slightly. -- Nick Schade Guillemot Kayaks 824 Thompson St Glastonbury, CT 06033 (860) 659-8847 *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
