jusavina said..With an 7.8 and a medium wing, you can't race under 10 knts and probably 12 knts for the heavier guys) with the RS:X convertible.
I wonder who they call "experts"

Experts probably are the promoters of the RSX Convertible.
The point you raise is interesting.
As a result do you think that below 10 knots will races be called off on the RSX Convertible ?
With the earlier Olympic classes Windglider, Lechner, IMCO MOD and RSX racing could take place at 3 knots plus.
Would the RSX Convertible need a modification ie a special light wind wing to be able to race at the low windspeed often found at Olympic venues ?
Will other "foiling board candidates" for the Olympics have these issues ?
