Tom,
In the video clip
[color=#000000]Tom,
In the video clip I watched, the sub was not underway. It was sitting still and then submerged on ballast. That's a static submergence, not a dynamic dive. So the nose down effect was not induced by hydrodynamics, it is occuring under static conditions, and is therefore a factor of weight and balance.
Actually, the CG of most NAUTILUS replicas I've seen (mine included) is slightly forward of the salon windows; yours is the only one I've seen where it's aft. Probably due to variables in the systems, weight and buoyancy distribution, etc. Whatever works, eh?
And I tend to agree]
