The overall plan and profile views actually came out fairly close to the DS12 without any reverse engineering. It does have slightly less rocker which may be a result of the sectional "fullness" compared with the DS12.

I'm still designing/thinking of the F12 as a kids cat trainer class similar to the purpose of the Optimist. Adults can make their own fun. Every so often my local club holds "regattas" with adults in optis...it's a funny sight.
