Hi FF
I have added some additional pics of the rear wing profile. It has a fine aero profile on the upper surface and a more pronounced aero profile on the lower surface. Forgot to mention the angle of attack of the front wing is approx 17 degrees which I have tried to show in the pics. Let me know if you want any more info?
The foil seems to work well. It is still early days for me but have had some great boat sessions and am now starting to prone foil. Coming from a regular surfing background I still have some work to do with sup foiling. Here is a link to one of the recent foil sessions showing the foil in action.
