Hi George;

(No offense) Euler/Navier-Stoke equations are generally applied to non-compressible fluids (i.e. water). As I recall, the most recent application had to do with 'singularies' in those non-compressible fluids - Steven Hawkings type stuff, in the bowels of black holes.

Your website offers one small, fuzzy picture of the same distant kayak as your total engineering solution. No specs, no performance standards, no hint as to whether you are cabable of even building a kayak, let alone building a good one.

Other posters on this board have demonstrated that they are capable of design, innovation, craftsmanship, in short, they SHOW US that they are doing it. Near as I can tell, you only TELL US that you can do it, but when asked how, you get in a snit.

Predicated on the information you have provided, if in need of an engineering solution I would trust Nick, Ross, Shawn, Mike, Kent, mick, , Joe, Vaclav, Hank, Dale, etc., etc., before I would you - - They produce, and you talk without any supporting evidence.

How about answering Vaclav's basic questions and demonstrating your engineering competence . . .

Best Regards, Spidey
