My mate and I have been building a foiling moth design of his over the holidays. Flat-pack cnc-ed carbon and foam sandwich panels put together in a female mdf jig, with the inside joins taped and frames and bulkheads installed in about 3 hours. Started a week ago and he is fairing the external hull join tapes today, with plenty of mountain biking, missed days and sleeping-in breaking up the build. I estimate about 40 man hours of build time.

Only items left to install are the wand push-rod guide tube and foredeck, should be water-tight and maybe launched by the end of the week, assuming some small parts have been ordered. All other parts are complete from another boat.

The hull build is extremely quick with this method and produces so little dust and fumes. Will definitely consider it, or a modification of this method, for future builds. Maybe flat panel sides and frames with a moulded bottom. There are some big boats being done this way.

Glass or carbon versions of your hull could be popular.
