wouter, you're not hijacking someone else's thread are you?

we all occasionally do it but try not to take it over and then poison it

You are right.

I'll shut up now.

Since there's agreement that a cat under 12 ft is not viable at all, a compromise is possible with a single platform and two sail plans:

a) School - kids under 12, single handed.

b) Standard - kids over 12, singlehanded and kids under 12, doublehanded.

An oversized sail plan for adults is also possible. It could require structural reinforcements adding some weight and longevity, which is probably an acceptable compromise as well.

I believe this is already compatible with the F12 project. What about the Blade 12? Can it be done?

"It appeared as though the tiller arms were longer, and the tiller crossbar simply was in front of the traveler tack with the tiller extension attached."
That's how the SolCat 18 is set up.
I like the way it works except it has to miss the rear stays, the crew, controll lines and hiking straps. I got used to it pretty quick.
It looks like a lot of these challenges would be irrelevent on this configuration.
