Jake:
I am anxious to see the first hull come out of the mold. I was going to make a US One Meter mold that clamped together. With the hull materials in place bolt the mold together and inflate a balloon inside to press the material against the mold. This way there would be no halves that need to be carefully glued and finished.
Another thought that was not mine is access to the inside. Make a round **** that is exactly the same shape as a coffee can. The lid would be easy to find, seal and replace, if neccessary.
I would like to know if you are designing the rigging to be transportable? I have seen many people take out fully rigged boats from their vehicles. Some of use do now have autos that are capable of that. To be able to take the mast off for transport would be very nice.
Later,
Dan
