I was wondering if their are any moldless composite designed
amphibians? I am definitely not an aeronautical engineer and don't
want to try to design something. Some examples of this type of
construction a Long-EZ, Cozy, Quickie, Q-200, Vari-Eze, Velocity

I know their are some drawbacks to this type of construction: mainly
that the strength to weight is less compared to molded parts, the
surface finish needs a lot of work and it must be stored out of the
sun.
