I got no VMG records, but by feel and just normal gps recording I would assume that the wind speed / VMG ratio is getting more extreme the lighter the wind.
As foiling speed does not change as much.
Makes sense?

Me too. In anything over 10 kts of wind, my speeds are about the same. My downwind angle does get better as wind speed increases though.Frank Rosin wrote: ↑Wed Apr 12, 2017 10:58 amI got no VMG records, but by feel and just normal gps recording I would assume that the wind speed / VMG ratio is getting more extreme the lighter the wind.

But readings like that are sadly very rare.
