And Good Morning to You, Gabriel!  Regarding your statement above, I can
only say "Yep!"   ;-)

Right again, I think.  General guidelines, combined with considerations for
special circumstances, and the ability to adapt when Murphy shows up, will
do much to reduce risks and increase safety.

Thank you for understanding what I was trying to say.  As for the specs,
I'll leave that up to you guys.  Mine is only about 1.25 tons; less than 40
cubic feet.  That's unusually small as PSUBS go, I think;  (it only ended up
that way due to design limitations imposed by replicating the Disney
NAUTILUS), and so I doubt my boat is a good example to base a "model for
safety" on.  But hows this: why not take a look at the subs in the Picture
Gallery; try to determine an average size and displacement, and work from
there?  That might provide a general guideline for experimental homebuilts.
Then again, you might want to do a seperate scenario on established designs
like the K-subs, since many people have them, and their  dimensions are well
defined.  Just a thought.....

Have a good day!
