Yes, it may be possible to pop to a plane in 6 kts but if you wanÃ‚Â´t to do something else than breaking the low-end record, you need wind and that starts at 7-8 kts. Another thing, nobody, I say nobody can say that itÃ‚Â´s 7 kts or 8 kts, since the wind varies all the time depending on where you are, measuring height etc etc. So, you might measure 5 kts on shore, get out there and get even airtime and then you come back stating " 2 m jumps in 5 kts wind", despite the fact that you have no clue whether the wind was 5kts or 9kts when you were running out there. It might have been 11 kts at 15-20 m height where your kite is pulling the power. The correct way of measuring kiting wind would therefore be (?) putting an instrument 15 m up the flying lines of a kite, have it standing still in zenith and take the reading. In these very low wind speed, it is close to impossible to compare different situations since layering of the air causes sometimes great differences in wind speeds. Specially when the water & air temperatures may vary from each other by as much as by 15 C.
As stated before, the real low end of kite hasnÃ‚Â´t and will not move downwards since anything below 7-8 kts is not wind, itÃ‚Â´s very careful movement of air. Also, the laws of physics with itÃ‚Â´s square roots etc etc. takes care of the fact that real kiting allways has and allways will start at around 7-8 kts.
Why worry about the kts or m/s. You will anyway take a look at the water adn the trees and then decide whether to get out there or not.
Well said !
But it seems, that the number 8-9 knots appear on most postings, with all the different rider weights.
One thing that the postings dont say, which influences the number, is HOW is the wind measured ?
8-9 knots, is that measured on a hand held meter, or a weather station ? (in DK standard height of wind measurements is 9 meter above water).
Many kiters are aware of the wind effects (slowing down) towards shore, so they might know how to measure the wind okay.
The difference might be 1-2 knots in strength (see phpbb/viewtopic.php?t=5159&start=0
There could be wind layer effects - but when most postings say the same, and many are so experienced that they of course dont post based on a single day (which could have had "odd" wind levels) - I think it seem right to state:
The low end of the biggest kites with a fairly big board (but not a Mega big board no...), where you can stay/go upwind , is about 8-10 knots for the average rider (75-80kg).
This is also my experiences with the biggest kites we see around.
