Hi,
Some thougths about apparent wind, mainly on hydrofoiling, to discuss with you ... and challenge some frequent assumptions i can read here and here, which I do not fully agree with...
Apparent wind (which as you know is due to rider own speed that adds relative wind upstream the kite), has strange and "whaou" effects on your ride, like tensioning your kite line so much higher that you feel the wind has grown up instantly ! But when you stop in the water.... then be carreful : the real wind is still light, when you need to come back if you lost the planning).
Ok, great feeling that we all love, but what i would like to "challenge" is the commonly used argument that this apparent wind is a major parameter to rider's speed, and that race kite efficiency is based on "using" this apparent wind.
I do not agree fully with this. To be a bit provocative to set my point (but not that much...) i would say that apparent winds does not help at all on your final speed .... you get my point ?
(Ok, do bot beat me on the teeth... we're here to discuss when not riding...
