I thought for super cavitating you needed thinner and shorter cord?The only way I can see that you even begin to get close to a super-cavitating foil within the rules is to use the rotation of the flap. So if the axis of rotation were a long way below the foil then when the red flap is "rotated" it would move from the left hand picture to the right. I think the rules on flexure would allow for the green to be those "flexures" (some of which are declared as part of the wing, and some part of the flap).
That would allow you to make the whole wing thicker at low speed and thinner at high speed, and also potentially bleed water from below to above the foil at the "joint". Whether this would work I doubt highly, and more importantly it would give very poor control.

seagull flaps, the only real video reality?Seagull flaps or morphing foil flaps?
You need thinner - which is what that was trying to do. I think it can be longer cord (that lowers the pressure difference after all). But I don't claim to be an expert on super-cavitation so could be wrong.I thought for super cavitating you needed thinner and shorter cord?
In the "morphing foil" thread I suggest a way to do that with oil pressure.

That could be fun and interesting for speculation too.Hull morphing nanotechnology. Serious, a year or so ago, I posted an IEEE article about nanotubes that can be used to change the shape of carbon structures electronically. I'll look for that post...
It looks to me that all the teams with new hulls (LR, NZ and Ineos) have really improved on that compromise anyway. Their end plating (above and below deck) is much smoother, and are all getting less impacted by touching than they did next cycle. I'm sure the others will too when they launch new boatsThat could be fun and interesting for speculation too.
At a much more 'basic level,' if there is a compromise in your hull's lower shape between preventing windflow bleeding to lee (Iike what a deck seeping main does) by creating an endplate effect, versus the hull shape best for when you encounter swell (to improve its ability to skim or cut) then maybe that lower part of the hull could be slightly 'flexible.'
