Re: Big sub was [PSUBS-MAILIST] Nekton, Delta

Well.. i was doing the planning.. To do a decent layout.  40ft of 8' dia would be a luxury cruiser.  but every time you loose a foot of hull dia.. you loose something like 1/3 of the useable space.  it's not fun once you try to fit people into a 6' tube when your average human is 5'10 or so.  And even then you have PASSABLE headroom only if you restrict passengers to the middle 1/3 of the hull.  Basicly you are limited to putting every passage on centerline, and having the head at one end, benches for passengers/sleeping space.  And the galley at the other end.  I have several ideas on how to deal with batterys and propultion spaces. Most envolve making a short "hallway" with the mechanicals on either side.  or just placing everything in a cabin at one end or the other of the boat.  preferably behind, or beside the head.  

8' wide and 20-25feet long provides a huge useable space. and this is what my latest work has been based around.  Not as fast as the longer, sleeker, designs.  But a lot more practical. and more stable becasue of the lower location of the ballast.  And I don't need to worry so much about the weight of the conning tower :)  I know it sounds like a luxury, but it's the only way to provide a driving place useable on the surface and underwater.  I find that vital.
