Not sure what you mean here but "lift" in the fluid dynamics sense does not always work in a vertical direction. Lift can act in any direction. I have always considered "lift" a poor choice of words to describe the phenomenon. I like "magic" better. :-) Interestingly enough almost any paddle can create lift so the Greenland style paddle does not have a monopoly on lift. If I misunderstood your comment just ignore this post. ;-) Cheers John Winters *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
