Mind you, all the large ocean going (French) tri's use assymmetrical (curved) foils. Many like to point at those as proof of feasibility.

There is a 12ft wide 3 sail M20(has an F20 C carbon mast) in the UK that has just had a special set of asymmetrical curved boards built and fitted.....it will be interesting to see how it performs this coming season...

Also I have just checked on the Nacra Sailing website and there is a trim sheet for the F20 C there that is available for download that describes the different positions to set the boards at depending on wind speed both upwind and downwind. Unfortunately it is took big a file, once converted to PDF, to attach to this thread. So please see Nacra F20 C trimsheet download
