I'd be concerned about a couple of things
here...
- Even
if you use acrylic domes, with the coning towers that far astern you won't have
visibility forward and down, which happens to be where it's most
needed.
- The
conning tower viewports are different in the two diagrams. Top diagram
version is good, but bottom version is not from a stress concentration
perspective. It would be OK if the window was cylindrical and went the whole way
around the tower, but not if only half way round as shown.
- All
I see for maneuvering is a horizontal and vertical rudders. That means you
cannot maneuver at all unless under way, and probably underway at quite a good
clip. Most of a time in a sub you will find you are almost at zero speed when
submerged.
cheers,
Alec

remember these?
they are up for revision.
using the same ballast sys but only one con tower and mini kota motors for multi
directional controls. also allowing for viewing front and rear. any info on cost
of large acrilic view ports like the dome ones used on conning towers. my plans
have been set back but now have purpose. I have 10-13 for completion. say hello
to the latest creation.
