As good neutral source I can tell you that these discussions (I think I´ve read fully all threads regarding F16 weight) are just the best promotion the class can have (after removing all personal attacks).
Macca is giving his Pro sailor view on the class, so don´t feel attacked, he always promote interesting discussions that benefit your class.

Too many times I just don´t sail and miss perfect conditions because of the hassle to rig and launch my F18 through the ramp on my own when no crew is available.
So a peformance light boat like the F16 is for sure an appeal for many Worldwide.

For sure you have Macca´s described risks in the future and you should take account on those.
But the intention of this class in my view right now is not becoming more popular than the all mighty F18, you just want a light boat to sail and with the creation of a class/rules provide a platform to race.

Keep up the good work.
Cheers,
