To push the hulls out to 75kg is no big deal, but it won't fit the majority of the kids then, if you want a larger displacement version, I'll just customize it for you but it probably won't make Wouter happy
I know everybody thinks I'm the reincarnations of the Devil, but I really don't care whether some person widens his F12 for himself. I actually adviced John (flatlander) to do the same last Januari.
It is just that I do believe that the F12 is for kids, it is an entry level cat, and I don't see how you can make it work equally well for 40-65 kg youths and 70-80 kg adults. It will be mediocre in both aspects or very poor in one of these roles. I personally choose to stick to the orginal F12 idea and go for a craft that is well suited to the 40-65 kg target group and refer the 70-80 kg sailors to the Hobie 16's, F14 or F16's.
For some reason people believe this conviction is some irrational opinion on my part. Weird. And then when I turn around there is another guy accusing me of wanting to make an F12 for myself and my own weight (90 kg). How can I be blamed of both at the same time ?!
It is an absurd experience.
Apparently it doesn't really matter what is said as long as everybody can blame dear old Wouter of something. Then everything is alright.
As far as I'm concerned its already a success because my wife who is "NOT" a sailor wants one see attached pics, ... I'm sure Aerynt and his boys will build 2 starting in the next few weeks and a couple of local clubs just approached me about a joint build of 16-18 of them.
This basically means that you are splitting of the main F12 project here. Which is something you can do but would you mind changing the name of your design at the same time. I think the F12 project has to run on this forum a little longer before we have a concensus we can act upon. As this project predates your involvement, it is only fair to reserve the F12 name for this project only.
