From catsailingnews a pre-production proto-not clear on whether they'll use uptip or z foils:
Viper F16 Foiler

Not an F16-my mistake-its a "Goodall Designed Viper Foiler" according to http://www.catsailingnews.com/

A nice Xmas gift for the foiling community, Thanks to Goodall Design
But for the community it raises one question:
This F16 Foiler is probably fiberglass/foam/vinylester built with some carbon reinforcement, maybe epoxy??
This F16 has aluminium cross-beam, with bolts& nuts.
All these construction technics have been replaced by much more expensive technologies for the A-Class
......to achieve a stiffer plateform in order to foil properly.
In addition on this F16, there are extra loads from the jib/front sails to address, and from the much higher righting moment
But at first glance this F16 foiler is foiling properly....isn't she?
This observation raises one question Do you see which one?

Bench,
We don't really know what this boat is constructed in. Their are carbon F16's out there, as their class rules don't (at least didn't) ban carbon in the hulls. The A-cat has minimum weight requirements that drive the use of carbon everything, more so than the whole platform stiffness argument-and I will contend that on the water, even my 05' Boyer Flyer with loose tramp and bolted beams (carbon) is stiffer than a 2012 F18, and will be just fine for foiling.
I'll also add that the choice of hull foam matters just as much as the choice between glass and carbon; Rohacell is about on par with Nomex Honeycomb and is still a foam, PMI so not legal in the F18 class which specified PVC but it isn't banned in the F16 class IIRC. I doubt Goodall are building in anything other than glass/foam/vinylester, as that is what they are setup for, but perhaps they went more exoctic. It will be interesting to see how this and the Phantom Essential hold up compared with the all carbon Flying Phantom, Nacra 20FCS, Nacra 17 Mk. 2 and to some extent the A's...strength and quality err on the side of carbon/epoxy/nomex

Standard Viper with L foils added being trialed buy a couple of Victorian F18 sailors. Broken quite a few boards where they exit the hull. Still work in progress however Goodall will be looking at 4 point foiling with Z boards, moving the cases forward if they were to build one.

The point is a foam/epoxy or vinylester technology boat, with bolted beams, can foil properly.
And it could be an interesting observation for the futur of A-Cat technology.
Soon we could see A-Cat, with similar technology, being upgraded successfully for foiling.
It seems very encouraging, for the A-Cat
Cheers

That's a bolted beam boat if I'm not mistaken, its a bit hard to tell exactly what it is, though I'm seriously tempted since all the hard work has been done...
