If the objective of Evolution kayaks was to create a lot of discussion around its design it looks as though they will succeed. Matt mentions the wasp waist in conjunction with reducing wave making resistance which, even if the principle does not apply to surface piercing craft operating at subsonic speeds, will still have many believers if Evolution says it does often enough and loudly enough. See http://www.hq.nasa.gov/office/pao/History/SP-468/ch10-4.htm for a discussion of constant cross section in airplanes. As for a kayak that turns like a ski - I was hoping some one would explain it. Nick's comment about semantics with regard to calling the boat a kayak has been made before in other contexts (Nick, did you study Jacque Derrida in university?) and he makes a good point although I still have trouble with it and wonder why people get upset when words have no concrete meanings. In any case I have a new power boat design that should qualify as the fastest kayak ever designed if I can only get Sea Kayaker to test it as a "kayak". One wonders how far a designer can depart from the commonly accepted forms with a design and still have it remain a kayak at least in the eyes of the public.

It would be interesting to see how a kayak that can back-camber will behave. I don't think too many paddlers would feel comfortable in one.

John et al, Personally I wonder if a sit-on-top is a kayak. Should it not be to canoe's as Boston Whaler's are to power boats? Simply a hull with built-in floatation? Can you not paddle a canoe with a double-ended paddle? Here's what "kayak" means to me: Something which gets much of it's stability from placing the center of gravity very low, has a closed deck within which the operator sits for protection from wind and waves, and can be knocked down and the operator can right the craft without leaving the normal position. Can seals be effectively hunted from a sit-on-top?

Ahh, it's just like old times around here: good ascii art from PeterO and the good Professor makes a return! Spring is in the air (north of the equator anyway) and my Tchaika is about to re-demonstrate its lovely stability curve. --allan *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
