This isn't exactly new, this build was done about 4 or 5 years ago. The regulars on here have probably seen it before, but we seem to have quite a few new people on board with the class recently, so I thought it was worth posting this link as a resource for anybody in the UK contemplating something similar.
The following link is to the French Breton skiff forum. It describes the amateur build of Cherub 3205 "Evey Hammond" using a plywood and carbon construction. My understanding of French is pretty hopeless, but if you just follow the series of photos through the thread from the beginning it gives a pretty good idea of how they did it.
As well as the construction technique, the other unusual thing about Evey Hammond was her hull design. They originally built her with a couple of steps in the bottom panel, the idea being that this might break the surface tension of the water under the hull and suck in some air to reduce resistance. I believe powerboats do something like this, some even having the exhaust blowing into the step to further reduce the density of the water under the hull. It appears the experiment wasn't particularly successful on Evey Hammond, so they later rebuilt the bottom panel into a conventional smooth surface.
Here it is:
