Of course, that goes without saying.
My references are for average weights, when no weight given.
If you are bigger/heavier, larger gear is used, just like with kites.
But you don't move the low end down.
And opposite, if light most typically stop at 5 max 6 m2.
But the relative low end, meaning wingfoil versus kitefoil can still be compared.
Sorry, the post I was answering is no longer present, so maybe an odd reply
