Great post, Craig -- found your blossoming love affair with a wing very intriguing. If it gets you another half a knot with the same effort, I'm interested. Small quibble, however: water _is_ compressible ... just not as highly compressible as air. And, you can definitely generate a high pressure within it ... or, a lower one. The Bernoulli effect is live and well in water, and so is the "airfoil" effect. Ostensibly, a wind paddle generates "lift," albeit not in a vertical direction, but along the longitudinal axis of the kayak ... and it does it using the effects of an airfoil. Sounds like the wing is working for you. -- Dave Kruger Astoria, OR *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
