Thirdly, what do you mean by "camber?" Although I have heard this word before, I am not 100% clear on its meaning.
Camber is the curvature of the profile along the chord. Some poster said above that apparent wind kites are higher cambered, but its quite the opposite. High camber (deep profile) means power at low speeds, but way too much drag preventing the attainment of higher speeds.
Higher cambered kites dont have more drag - they actually have lower drag, at the same high lift coefficients
Of course they also got power at low speeds, because of the higher max lift coefficient.
And if these kites are high AR (needed, otherwise they WILL have a huge amount of drag at high L.C.), they will generate an enourmous amount of power when apparent wind strikes - that being when ridden fast or flown in sinus
An example is the North Dyno.
High Camber - High AR.
This kite is a pure power machine, when you ride it fast, and the apparent wind kicks ass on such a kite - GREAT !!!
Whereas a low cambered wavekite, low AR - will not gain much if flown fast, compared
This is the whole idea of a wavekite though - that it should never have powerspikes at all, like the apparent wind kites has
I think some are confused about the fact that low cambered kites (with no power), NEED to be flown faster, in order to GET any power, for the same size.
But this is just an unfortunate mishap, and not something wanted - unless you ride waves.
If you exaggerate the camber, you might get even more low end at low speeds, but not max L/D and not very efficient.
When you reach this point, yes, the apparent wind will not have the same beneficial effect as maxed L/D kites will, that is true.
But IMO most kites are far from that camber - because we need way more range and depower in general in kitesurfing.
A low cambered kite has a huge amount more wind range than a high cambered one - but of course its lowend is much worse.
Because the high cambered kite will still pull and have drag even with fully slack lines - whereas a totally flat kite (no camber at all and a thin LE) could almost be held in infinite high winds (and still be able to lift somewhat, believe it or not)
