And what do you know ... !
Take a look at this :
Notice the free standing rig. It is very similar to what we were thinking of doing on the F12.

The boats seems to have good speed (despite it weighting 110 kg = 240 lbs). Figure an F12 at 60 kg !
for its specs scroll down this page
http:/
Length : 3,65 m / 12 ft
Beam : 2,25 m / 7,4 ft
Weight : 110 kg / 242 lb
Draught: 0.59 m /2 ft
Crew : 1 - 2
Boom : 2,50 m
Sail area: from 8,50 m²
Sailing from 3 to 30 knots of wind
The latest version of the F12 had :
Length : 3,70 m / 12.1 ft
Beam : 1.85 m / 6.07 ft
Weight : 60 kg / 132 lb
Draught: 0.50 m /2 ft
Crew : 1 - 2 (max 120 kg)
Boom : 2.00
Sail area: from 7,50 m²

Personally I think the blowkart style **** is a mistake, except when wanting to attact total novices to sailing at resorts. It will add ALOT of weight and make assembling take alot more time.
My main interest in this design was the free standing rig, the looks and the speed this craft still achieves. I see it as a sort of validation conception. Now the F12 must refine the design to a truely outstanding catamaran. In my view this means a normal trampoline setup with two straight beams in combo with a normal rudder setup.

This project is still close to my heart, but sadly it is on hold till I have some
play money
to spend on this project. Will probably take another year or two.
I'm still looking at new ways to do this though. And I think the wishbone rig (as a windsurfer) may have the best cards at this time. Mostly because then there will be no need to have a kicking strap or traveller on the boat, this simplifies the design another step. And with a wishbone rig you can keep the sail tensioned all the time and have the battens pop nice and easy during a tack.

Cheshire cat : 7900 USD
F12 : 3500 USD (or less)

But seriously the F12 is fundamentally different from the Cheshire cat both in target group and concept. The F12 has a design requirement to be fully assembled from its basic parts under 10 minutes (5 if I get the trampoline fixture right), with as added requirement that all parts (except readily available ones like small blocks) must be homebuildable as well.
