[PSUBS-MAILIST] Non developable surfaces

[hank pronk]

I have to agree with Alec, it is rare to take a sub out without needing touch up paint.  I also think a sub should not have a front mbt.  The MBT's should be on top and on the sides.  The sides is best because of surface stability to enter the sub, unless it is barge or ship launched.  Emile nailed it.

Hmmm. If it were that brittle I would expect trouble in aeronautical 
uses. Might be a not-properly-annealed-after-forming problem.

Besides, how difficult would it be to provide a buffer that doesn't 
block too much of the view? That would take care of dock and support 
vessel bumps, and it seems to me that reasonably competent handling 
should obviate contact with rocks on the bottom?
