Hi
For the Session with the "one Design sail"
i used my biggest Foil with 2400 square centimeter and 110 cm Span
I have build this one for a 72 year old friend who wants to learn Windfoiling He wants a slow Foil with early takeoff
The Design ist similiar to the biggest Wingfoil Foils used in our Lake but with thinner profiles
(Mid Aspekt)

It works quite well for him and he can fly steady over a few 100 m with that thing

If the Wind ist close to 8 knots i use it with my 5,6 Foil freek , exocet Board and AFS Carbon Mast

Balz Mueller showed that ist possible to sail with an old school Triangel sail

Yesterday someone from our Windsurfing club rented me a similiar one and i give it a Go

What a fun in light Wind.

That damn thing has more bottem end power than my 5,6 Foil freek
It kept me going in about 8 knots and was flyinng in about 5 knts
Once a gust was hitting me it was very diffiucult to Control so it blows me from the Foil once in a while
I was surprised that there we're no major changes necessary in mast foot position
Used my standard free ride Foil
Speed ist very slow with about 15 to 16 knots only

But again
On our tiny Lake in Low Wind conditions a Lot of fun

Hast anyone else tried a similiar old sail

Hi
My recommendation
Shim the Back Wing to more angle of Attack

I have done it in several Foil Setups and its very efficient
Ideally measure your actual Angle with a cheap Tool and increase by 1 to 3 degrees
Possible even with washers or a small 3D printed shim
