There is -plenty of water out there...let Wouter do his thing with the teens and interested Adults. You do your thing with the 7-12 year olds. Build whatever you want, no one is stopping you... if the bickering keeps up, by the time you come to some sort of agreement (if ever) the current 7 year olds will be too old (big) for the platform that is being arguing for.

Here the best way to settle this…let all interested parties go out on their own, design and build their ideal F-12…then get them out on the water and see which ones perform…Not to be offensive but this “put up or shut up” approach could be much more productive than just arguing back and forth with “I Think” “You Think”

Those that do not have the expertise to design and build a proto type would do best to leave the decisions as to length/beam/weight/sail area etc. to the ones that are willing to put their money where their mouth is…either way, once they are on the water the fact will be quickly separated from opinion.

Best Regards,
