these points are not enough to define the correct shape...

If you will not find more refined coordinates you then can do the following:

You can load coordinates you have to x-foil or XFLR5 and refine the shape (I think in x-foil you can increase number of points up to 130 and up to 250 in XFLR5).

I'm sorry, I have the same problem, I haven't dabbled with Xfoil, can you explain more on how to obtain more point?

And, can anyone share a more accurate S809 coordinates file other than the 60+ points on NREL website?

Thank you so much.
