Re: [PSUBS-MAILIST] OSS Pressure hull basic layout.
OK. First, the swamping thing...You're right, it wouldn't be too cute to be swamped
from the hatch...I wasn't trying to convey any dimensional info with the model, only
the general perspective...Which is why I chose 3D. Here's the reason I would want two
hatches: This is a two man sub. Do I really want two hatches? You've got to be kidding
me! Heck no! But I also have never been a big fan of slithering like a snake. Not my
style. If the hull diameter was greater then I would advocate a single hatch. Gosh this
weight constraint makes things exciting! It wouldn't be that difficult at all if this
was a one man, but two...Whoa. What about a large conning tower with both passengers
back-to-back? It's not like the view behind the sub would be any less exciting for the
passenger...Well, let's see if we can bang out something...
