Foils

[Ricardo Aráoz]

Hi, in page 1 of the Tiki building instructions (A3 booklet) in point #3 it says "plane leading edge of skeg and leading + trailing edge of keel to foil shape (see sheet Nr.1)". 

Now in sheet number 1 it says "keel planed to a foil section before hull is assembled".

And that's it. Haven't found the shape of the foil section anywhere.

Checked the internet and there are various NACA foils, and it seems overly complicated. Is there a proper shape somewhere? Or should I learn about these NACA foils before doing this?

Thanks

Ricardo
