As for a rectangular sail being optimal. It might well be for the light
winds those boats sail in and the height restrictions on the mast. They
won't even go out in anything above 18 knots and that's sad. Imagine
that.
Boats costing millions and so unseaworthy a Catalina 25 takes higher
winds
in stride.

The limits for the Vuton cup are 7 - 23 Knots. Since wind pressure
increases as a square of the wind speed a 23 K wind exerts 1.6 times
the pressure of an 18 K wind.

I been saying all along, "Sheesh! Those America's Cup boats sure do have
short masts!" lol

What a Wilburism
