****e load of parts to rig up down the beach, but hey if it works for then why not. !
Looks good for land but I reckon you'll need at least a second set of floaties if you have to water start it.
It'll be a beautiful / fantastic amount of design and calcs for all the levers and cams to rotate to get the foil on the other side with the rig flip.
Not sure where they got their lift /drag curves from on the Pdf
There is not that much difference between single and double surfaces . Extra lift is due to the Fx 13% camber vs the eppler 9% the penalty for this is 2.5 times more backhand pressure (Cm , coefficient of momentum). drag not much different.
