I have a gofoil kai, it's 62 x 23cm.
With the wing shape as it is, I'd estimate projected area to be a little less than 62 x 23 x π / 4, so probably around 1000 - 1050cm2, definitely well less than 1200.
I don't know how to measure it accurately.
So the 120, 160 etc don't make sense except maybe relative to each other.
