7 m2 LEI needed in 10 knots.
1100 or 1200 cm2 wing
26-27 m lines
Not possible on smallest board though, need my medium board.
And underpowered so would choose a 9 m2 in 10 knots.
In this wind there is not much wind down at the surface when you loop the kite down...
With a 5 m2 LEI i need 12 knots to ride, but too small for fun usually.
Assume you ask about the smallest size possible to waterstart and foil, and not what we choose?
