It is definitely a good method to be used by armature home builders. Don’t know if you have been checking the sshhh thread there is a little bit more on the building there.
My hulls are a little overweight as I used a heavier cloth than needed, because I had it laying around in my workshop. If I remember right I ended up at something between 13-13,5 kg, it should be possible to make them around 12 kg.
When the jig is setup you can rip the strips, lay them, glass the inside, install transom and frames make the beambox and the fittings for forestay and shrouds in one day about 6-8 hours for one hull half.
The two halves made its not a big deal to join them and glass. In total I made Had the Tabby on the water in five weekends guess 50 hours (not painted).
