That pentagonal sections idea reminds me of
building an igloo and also of the keystone and construction in a Roman arch.
Interesting.

I've wondered about doing
that for an entire hull. Not in acrylic, necessarily, but in whatever
material is desired. The hull becomes a structure made of pentagonal
pieces. If I could figure out how large each pentagon has to be to
result in a hull of the proper size, I'd be able to think about this more
clearly. The math eludes me so
far.
