Jay, The mock up was my first experience with molds and fiberglass. The mock up
"squats" a bit out of round from it's own weight but the general dimensions are
close. The hull will be 2 hemispheres and a cylinder. I am working on
strength/stiffener calculations now. I want 800 ft.
The front hull piece (with the dome opening) was already fabricated (salvaged
from the PC-1402) so it has ABS certification. I believe this is the major area
of hull strength issue due to the large opening but my feeling is Perry got it
right.
Now that I have the pressure hull dimensions established I can do all the fun
math.
Thanks,
Steve
